Beijing issues new regulations: electric bicycle battery pack should sound alarm when it is overheated.

  (Reporter Wang Wei) The Beijing Youth Daily reporter learned from the Municipal Market Supervision Bureau that the Beijing electric bicycle group standard "Technical Specification for Lithium-ion Power Batteries for Electric Bicycles" was recently revised and will be officially implemented on June 19. A total of 19 items were added to the group standard, and 20 related technical requirements were supplemented and improved. The project of mutual recognition and collaborative identification between battery pack and whole vehicle is the first time officially listed in the national standard. By increasing the mutual recognition and cooperation function of the battery pack, the mutual recognition and cooperation identification between the battery pack and the whole vehicle and between the battery pack and the charger can be strengthened, the illegal assembly and modification behavior can be curbed, and the explosion and fire risks caused by the mismatch between the electric bicycle and the battery can be prevented. In addition, the standard requires that when the battery reaches 80℃, an alarm sound should be given within 30 seconds.

  According to reports, the newly revised group standard highlights the safety of products. On the basis of the quality and safety management practice of electric bicycles in Beijing, the requirements of mutual recognition and collaborative identification of battery and whole vehicle, battery (monomer) identification, acupuncture, thermal abuse, overdischarge and external short circuit are put forward for the first time. The group standard takes the lead in applying the mutual recognition and collaborative identification of battery and charging device, the over-temperature alarm function of battery, and increases the safety items such as battery handle strength and salt spray. The group standard also specifically defines the functions of battery management system and refines it.

  Among them, the mutual recognition and collaborative identification of battery pack and vehicle, thermal abuse of battery (monomer) and acupuncture detection items are officially included in the standards for the first time in China. By increasing the mutual recognition and cooperation function of the battery pack, the mutual recognition and cooperation between the battery pack and the whole vehicle, and between the battery pack and the charger are strengthened, the illegal assembly and modification behavior is curbed, and the explosion and fire risks caused by the mismatch between the electric bicycle and the battery are prevented; By increasing the items of battery (monomer) acupuncture and thermal abuse detection, the safety problem of lithium battery caused by high temperature and diaphragm rupture after collision can be effectively solved.

  The over-temperature alarm function of battery pack added in the newly revised group standard requires that when the internal temperature of battery pack or the temperature of a battery reaches 80℃, the vehicle or battery pack should give an alarm sound within 30 seconds, which is of positive significance to the safe use of electric bicycle users. The newly revised group standard also improves the requirements for the stability of batteries (monomers), improves the safety performance index of lithium battery packs, and effectively prevents the risk of fire and explosion accidents of lithium batteries.

  It is reported that Beijing implements a product catalogue system for electric bicycles. The Municipal Market Supervision Bureau said that after the implementation of the newly revised group standards, the original group standards will be abolished at the same time. The over-temperature alarm function of battery management system (BMS), mutual recognition and cooperation function between battery and vehicle, battery (monomer) needling and battery handle strength and other new technical indicators related to safety will be included in the catalogue of electric bicycle products, which will further enhance the safety of selling lithium-ion batteries for electric bicycles in this city.

Wearing white protective clothing, we are like a great white guard for health, and we will definitely protect you from going ashore safely! | Angel Diary

  In the face of the novel coronavirus epidemic, there are such a group of people who are racing against death. They are parents, wives, husbands and children … … But in the face of the epidemic, they are "angels" dressed in white robes. Voice of China’s "Angel Diary", the fourteenth article, records the daily work of the "angels in white" and captures the touch of the frontline of the "war epidemic".

  It was cloudy on February 10th, 2020.

  I am Wu Man, a nurse of endocrinology in Houhu Hospital of central hospital of wuhan. Today is the 17th day of my work in the front line of the "epidemic". On February 8, when I was nursing the patient Mr. Yi Lao, I overheard him say, "Tomorrow is my birthday, and I really want to eat a bowl of longevity noodles." After work, I posted this in the work group, and my colleagues wanted to do something for Mr. Yi Lao. Huang Ruxian, a nurse in gastrointestinal surgery, accepted the task of longevity noodles. Near noon on February 9, Huang Ruxian made a birthday cake with bread at home, inserted some candles, and then made longevity noodles. I, Huang Ruxian and other nurses sent cakes and longevity noodles to Mr. Yi Lao, and played birthday songs, clapping their hands to bless him and cheer him up.

  Mr. Yi Lao said to us: "You have made me spend an unforgettable 76th birthday, and I have regained my confidence in defeating the virus. Although you are wearing protective clothing and masks, you can’t see your faces clearly, but I believe you are all the most beautiful angels in white. "

  On February 10th, 2020, it rained in Wuhan.

  I am Dr. Wei Qi from the Department of Hepatobiliary and Gastrointestinal Surgery of Wuhan Hankou Hospital. Today is the 20th day of my participation in the fight against COVID-19 (rescue work), and now I am mainly responsible for the emergency treatment and management of critical patients in fever clinic. The emergency room has been overloaded for a long time, and we have worn all kinds of protective clothing and n95 masks. It is really different every day, but we can still overcome it.

  My wife is also a nurse in our hospital. Now she is in the isolation ward. The most worrying thing is that she has two babies, who are taken care of by her grandmother alone in the country. She is a very strong person. Every time she calls, she says that her family is fine, so that we can work in the hospital with peace of mind. But I can imagine that a six-year-old and a three-year-old child are naughty, and she may even be in a hurry to cook. Now I hope that the people of the whole country will work together to overcome this epidemic!

  It will be cloudy on February 10th, 2020.

  I am Wang Yanli, a doctor in the Department of Respiratory Medicine of Wuhan Children’s Hospital, which is the only designated hospital for children in novel coronavirus, Wuhan. My sisters and I have been working in the isolation ward for 15 days.

  Two days ago, it was the Lantern Festival. Most of my colleagues forgot this festival, and the careful head nurse Li Wenqing didn’t forget it. Early in the morning, after arranging the affairs of the department, she quickly asked the nurse in the rest area to cook the dumplings, and sent the hot dumplings to each hospitalized patient: "Come, have some sweetness." Although we didn’t eat dumplings or reunite with our families, it was warm to look at their smiling faces. There was something warm on my mind that day. In the afternoon, I went out of the ward and went back to the rest area to prepare for dinner. I found that the nurses and sisters were all busy in the small classroom, and soon the table was filled with all kinds of food we could find, as well as a small cake. I just know that the head nurse’s birthday has passed two days. Everyone made an appointment to make up a new birthday for the head nurse. As soon as the head nurse entered the door, she was moved to cry. Each of us was more than one meter away and sent her blessings one by one. The pistachio of the department said that we will never forget this day.

  It was cloudy on February 10th, 2020.

  I’m Jing Wong, head nurse of the first isolation ward of Xiaogan Central Hospital. Today is the 12th day for me to take part in the fight against the COVID-19 epidemic. These days, I am mainly responsible for ward management, clinical nursing and organization and coordination with Chongqing Aid Hubei Medical Team.

  In addition to basic treatment, we will also give spiritual encouragement to patients every day and strengthen their determination to recover, such as our grandfather in bed 37 — — The 67-year-old critically ill patient was very depressed when he first moved in. Through our daily psychological comfort and chat, he is now obviously relieved compared with before he was hospitalized, and he can even eat by himself. I hope all the patients in the hospital have the same determination and belief in recovery as him. At this moment, if there is a fast-forward button, I hope to go directly to the day when we win the battle!

  It was cloudy in Wuhan on February 10th, 2020.

  I am Ge Shengting, a nurse in Hongqiao Campus of Huashan Hospital affiliated to Fudan University in Shanghai. Today is the seventh day of my work in the front line of the "epidemic".

  After the construction and planning a few days ago, the Wuchang shelter hospital where we are located has gradually entered the right track. Today, it’s my first time to enter the cabin. Seriously, even if I do a good job in psychological construction and stand in front of the gate of the "patient area", my heart beats faster. I pushed the door open and the scene behind it was peaceful. From 8: 00 am to 12: 00 noon, the first "4 hours" I entered the warehouse whizzed past. My uncles and aunts, like my relatives, care about whether I am tired or not. Although my back is soaked, I still don’t want to miss every second of caring for them. Our shelter is like a big ship sailing in the stormy waves, and we in white protective clothing are like a great white guard for health. We will protect you from going ashore safely!

  It was rainy on February 10th, 2020.

  I’m Liu Qihui, a nurse in the ICU of cardiac surgery in Hainan Provincial People’s Hospital. Today is the 14th day of my arrival in Wuhan and the 11th day of my fight against COVID-19. I called my grandparents last night and lied to them. I was busy in the hospital (Hainan Provincial People’s Hospital) and may not have time to call them. As a result, they said they already knew that I was in Hubei. I hope I can call them often to report my safety and pay attention to safety! I stopped for a few seconds to reply. Okay. Grandpa used to be a soldier in the 34th Division of the 12th Army of Nanjing Military Region. He said, "When one side is in trouble, all sides can support it. Now it’s your turn to go to the battlefield. Be sure to pay attention to safety and take care of yourself! " Grandpa, I will definitely come home to see you when the epidemic is over. You from afar, please rest assured that we will return safely!

  It was cloudy in Wuhan on February 10th, 2020.

  I am Zhou Jienan, a member of the National Emergency Medical Rescue Team of the Second Xiangya Hospital of Hunan Central South University. Yesterday was my 29th birthday, and I came to Wuhan from Hunan. Before I left, I went to the hospital staff barber shop to get a haircut as my special birthday present. This inch is the same as mother’s.

  In May 2014, her mother, who was also a nurse in the Second Xiangya Hospital, underwent radical mastectomy on the right side and received four stages of chemotherapy. Before she lost all her hair, she decided to take the initiative to give up, and shaved a monk’s head without stopping. I knew she was afraid that I would look uncomfortable every day. After shaving my head, my mother smiled and asked me: Is it okay?

  After four courses of chemotherapy, black grass quietly emerged from her head. Slowly, my mother made the transition from a buzz cut to a lovely and delicate short perm.

  On February 9, with the same optimism, I cut a cut with the same paragraph as my mother. It not only saves the time of care, but also facilitates the putting on and off of isolation and protection facilities. Taking advantage of my 29th birthday, I would like to say thank you for your hard work, for giving birth to me, for educating me to grow up with me, and for teaching me to fight the disease with the same inch.

  I will come back safely. At that time, we will abandon the masks. I want to tell you something about my trip.

China online celebrity economic observation in the past year: 50 lipsticks can be sold in one second.

  Perspective of online celebrity’s economic fieldManufacturing marketing myth:

  You can sell 30 million yuan of clothes and 15 thousand lipsticks in 5 minutes.

  Shaping the fan economy:

  The data shows that 76.6% of the "post-95/00" will "plant grass" (under the recommendation of others, they will have a desire to buy a certain commodity) and online celebrity will recommend products.

  Faced with regulatory issues:

  In response to related issues, relevant people suggested that in the future, big data technology and information technology should be used to support the law enforcement of online transactions, and a unified supervision system and regulatory agencies for Internet transactions should be established.

  Earlier this month, 2019 Weibo Super Red Man Festival was held in Chengdu. The gathering of online celebrity, MCN organization (content incubation and management organization) and mainstream platforms in the whole field provides an opportunity for observing online celebrity’s economy. Why did online celebrity bring the goods? Who is being planted with grass? Where is the future of online celebrity’s economy? Over the past few days, Chengdu Business Daily-Red Star journalists have talked with practitioners in various links of online celebrity’s economic industrial chain and observed online celebrity’s economy in the past year.

  With the help of Tik Tok’s color test, Li Jiaqi, the "lipstick brother" who captured thousands of girls, sold 15,000 lipsticks in five minutes, setting a myth of carrying goods with a turnover of 3.53 million in five and a half hours of live broadcast … … Online celebrity people with their own traffic have become walking "cargo planes". Under their recommendation, one network explosion after another was born.

  It is not difficult for Zhang Dayi to sell 30 million yuan of clothes in five minutes. Its Taobao shop became the first Taobao shop with sales of "double 11" exceeding 100 million yuan. As a major shareholder, Ruhan Holdings also listed on NASDAQ in April this year, becoming the "first share in online celebrity". Why did online celebrity bring the goods? Who is being planted with grass? What are the feasibility, uncertainty and problems of online celebrity’s economy? How to make it develop more healthily and orderly?

  On August 31st, last year, Zhang Dayi launched Mickey’s 90th anniversary joint venture with Disney, which sold 220,000 pieces that day and exceeded 30 million in five minutes. Just at the 2019 Weibo Super Red Festival held in Chengdu, Zhang Dayi revealed The Secret Behind.

  "Nowadays, young people buy goods not only by looking at the product itself, but also by caring about the label meaning behind the product. Presented with rich content and forms, let brands and users find resonance in label preferences. " On August 3, Zhang Dayi, who appeared in Chengdu, mentioned that for the generation born from 1996 to 2010, label preference is one aspect to please this part of users.

  According to Accenture’s "Global Post-90s Consumer Survey China Insight" report, social media will become the main consumption channel for post-90s consumers in China, and about 70% of the respondents expressed interest in shopping and trading directly through social media. "Social media is just the need of young people. Use social media such as Weibo to empower products, create products with social attributes for users, and make products become social currency." With the fast pace of life and increasingly scarce time, Zhang Dayi believes that users need different experiences more.

  "Same paragraph, joint name, limited edition … … These keywords can reach the high point of contemporary young people. " Zhang Dazhao told reporters that the expression of selling goods should be straightforward. "In the era of rapid expansion of information, it is difficult for everyone to spend a lot of time speculating on the meaning behind the information. It is very important to say that it is understandable and it is also the basis for online celebrity to communicate with users." Zhang Dayi said that live broadcast is the most efficient form of expression at present, and it is dynamic and two-way. Therefore, starting from 2016, she will launch live broadcast every month to help users "plant grass" and "pull grass", and will also use marketing methods such as lottery coupons to enhance the stickiness and interactivity of fans. Zhang Dayi believes that social media is changing the way goods are sold.

  Changes in consumption habits

  Sina Weibo data shows that

  76.6% "after 95/00" will be "planted with grass"

  Behind Zhang Dayi’s marketing myth of "selling 30 million yuan in five minutes", Kiki, a 24-year-old native of Chengdu, is there. Kiki is a new media operator. She was an online shopping enthusiast in college. She followed many online celebrity on Weibo, and Zhang Dayi was one of her earliest bloggers. Outside of work, it has become her daily routine to visit Weibo and "buy in buy buy" with online celebrity. Kiki’s current salary is about six or seven thousand yuan per month. In addition to daily expenses, "the rest of the money is almost entirely contributed to online shopping", and the categories include clothing and cosmetics. Kiki told the Chengdu Business Daily-Red Star journalist that online celebrity’s recommendation almost became the only reference factor in her online shopping choice.

  How much does online celebrity’s economy affect the post-95/00 generation?

  The relevant person in charge of Sina Weibo provided the reporter with a "2018 Weibo E-commerce Industry Survey Questionnaire". Through a survey of 2,153 samples, it was found that 76.6% of the "post-95/00" will "plant grass" products recommended by online celebrity, and 18.8% of them will choose to buy directly after being recommended by a trusted blogger; 73.7% of the post-90s generation will "plant grass" for products recommended by online celebrity, and 18.9% of them will choose to buy directly after being recommended by trusted bloggers. Another "2019 Global online celebrity Marketing Survey" pointed out that two-thirds of consumers said that as long as online celebrity revealed its relationship with a certain brand, they would believe the product recommendation; 88% of consumers said that they had bought a certain product on the recommendation of online celebrity.

  According to Wang Jia, COO of Tastemade China, online celebrity’s economy was sought after after after 95/00 because they expressed their demands.

  “‘ After 95/00 ’ The biggest feature is that the mental structure has just formed, ‘ Self-awakening ’ It is their label. " Wang Jia told Chengdu Business Daily-Red Star News reporter that these people have the impulse to be opinion leaders, and it is thoughtful to try to express their opinions. "The desire to become an opinion leader forces them to pay attention to a lot of content, but this group of people born in the Internet age ‘ New Humans ’ All of them are characterized by fragmentation of information and diversification of choices. "

  Change of strategic location

  "Who controls the key nodes of information dissemination?

  Who will have the opportunity to quickly become popular. "

  According to the data released by Sina Weibo, in the first quarter of this year, there were 465 million monthly users in Weibo, an increase of 54 million year-on-year and 203 million daily users. As of June this year, the overall scale of Weibo’s head authors has reached 780,000, among which the scale of big V users is nearly 60,000.

  "In all fields, future opinion leaders (KOL) are the core strength. Like the brand’s continuous rejuvenation, KOL and the brand are all aimed at reducing decision-making costs." Feng Min, CEO of Hangzhou Ruhan Holding Co., Ltd. told reporters that in such an era, the rapid economic development of online celebrity is a necessary and irreversible process. Ruhan Holdings, the "first share in online celebrity", owns top KOLs such as Zhang Dayi and Daikin, and was listed on NASDAQ in April this year.

  "Only when the aesthetics in a certain field has output to fans and can help fans improve their decision-making ability can they become online celebrity." However, due to the aesthetic diversity of human beings, KOL in more and more subdivided fields has also appeared. Therefore, in Feng Min’s view, whoever controls the key nodes of information dissemination will have the opportunity to quickly become popular in a very short time. "As a KOL or MCN institution, it is even more necessary to improve the efficiency of information transformation. We will choose the most suitable platform for content distribution according to KOL’s own attributes. "

  "There is no Zhang Dayi after Zhang Dayi. The head KOL, like the head players, is unique and limited. We can guarantee that our system will continuously produce players who are qualified to play professional games, but we cannot guarantee that every KOL is Messi. " Feng Min told reporters that becoming a superstar depends on the right time, the right place and the right people. Nevertheless, "other head players can still provide their own strength for the wonderful presentation of the game." Feng Min said.

  Three major problems

  Value-oriented sustainability of consumption experience

  In recent years, the "planting grass" mode of social e-commerce platform has brought huge traffic and benefits, and many video and blog platforms have followed suit. Previously, the removal of the little red book undoubtedly sounded the alarm for the simple and rude "planting grass" model.

  Thinking of responsibility

  Only responsible for promoting, not responsible for after-sales consumer rights. Where to put them?

  In the view of Sun Quan, a marketing professional, online celebrity’s economy has overcome the alienation and intangible falsehood of exquisite advertisements in traditional e-commerce propaganda, flattened product information, and brought more direct use and experience introduction through the use of people themselves, assuming that they are real people from the same consumer perspective. Online celebrity will also give feedback and answers according to the concerns and needs of fans, and recommend them accurately and strongly. For advertisers, integrating online celebrity and doing a combined marketing is more accurate than traditional propaganda, and it has short cycle, quick effect and can be shipped quickly in large quantities.

  On the other hand, Sun Quan thinks that the negative impact of online celebrity’s economy can’t be ignored: a large number of online celebrity started from grass roots, and they don’t have a perfect research and real use cycle when they receive advertisements, only responsible for promotion, not after-sales. If the manufacturer is irresponsible and just wants to make a quick cash deal, then once there is a problem with the product, it will bring a bad consumer experience, "consumers will have a hard time saying."

  Thinking of influence

  How to curb teenagers’ lack of judgment to show off their wealth and keep up with the joneses?

  Zhu Wei, deputy director of the Communication Law Center of China University of Political Science and Law, pointed out that "planting grass posts" are essentially advertisements, because they can be realized directly through content drainage. According to the provisions of the Interim Measures for the Administration of Internet Advertising in 2016, media platform operators, advertising information exchange platform operators and media platform members should take technical and management measures to stop illegal advertisements that they know or should know.

  At the same time, showing off wealth and keeping up with the joneses may have a very negative impact on teenagers. "They lack judgment, are easily biased, and have psychological problems. In serious cases, they will also participate in this comparison through naked loans and other channels ‘ Bubble ’ Medium. " Liu Chengbo, deputy director of the strategy department of the Education Development Research Center of the Ministry of Education, said.

  He Zhicheng, a lawyer of Shanghai Junlan (Wuxi) Law Firm, suggested that in the future, strong big data technology and information technology should be used to support the law enforcement of online transactions, build a unified national Internet transaction supervision system and supervision institutions, and at the same time promote the autonomy of online platforms, and make up for the lack of legal rules with personalized autonomy rules.

  Thinking of mode

  From prosperity to decline, are many marketing really "omnipotent"?

  In fact, there are quite a few cases of "online celebrity" roller coaster from prosperity to decline. How can online celebrity get rid of the fate of being replaced by the next wave of online celebrity? Shen Guolin, an associate professor at Fudan University’s School of Journalism, believes that if you want to bid farewell to the short "fresh-keeping period" and truly become a "century-old brand", what you need is a real word of mouth and a loyal customer base. In other words, stores should practice their internal skills in "invisible places" instead of making an "embroidered pillow".

  Qi Xiaozhai, president of the Shanghai Business Economics Association, also said that when consumers choose "online celebrity", what they value is creativity and face value, which is a matter of opinion. However, "online celebrity" should also have a "core", and it will be "cool" sooner or later if it relies too much on external contrast such as marketing.

  A trend

  "online celebrity’s economy will gradually return to rationality and return to the commodity itself."

  Sun Quan said that the rise of online celebrity’s economy stems from the traffic bonus caused by the Internet explosion. With the normalization of Internet commerce, the strengthening of the state’s supervision over the social influence of Internet celebrities, and the consumers’ pursuit of better consumption quality and experience, online celebrity’s economy has entered the second half of the Internet era.

  "online celebrity’s economic form of bringing goods still has room for continuity, but it will gradually become rational, and the final foothold and the key to promoting the transaction will return to the goods themselves." Sun Quan said.

  Wang Jia also mentioned that the birth of a large-scale incubator base in online celebrity in recent years marked that "online celebrity economy" has embarked on the fast track of development. However, the rapid development of "online celebrity economy" has also exposed shortcomings in content and product quality. Wang Jia believes that there are indeed some content e-commerce platforms with large traffic and strong carrying capacity, but some consumers have a bad experience. In his view, this is due to the entire e-commerce infrastructure rules, consumer protection system and business quality control system. Not yet fully established. "This is just a process. From a long-term perspective, the platform has recognized these problems and started to introduce various policies to guide merchants to improve product quality and service capabilities." (Chengdu Business Daily-Red Star Journalist Peng Xiangping Comprehensive Xinhua News Agency)

Collaborate for innovation and explore new knowledge hand in hand-China has made great achievements in international cooperation in science and technology.

  The neutrino experiment project of Daya Bay nuclear reactor was led by scientists from China, and about 40 institutions from seven countries and regions participated in it. The picture shows the relevant experimental equipment.

  Recently, the experimental device designed by China arrived at the International Space Station with the Falcon 9 rocket. With the help of commercial cooperation mode, Chinese researchers successfully bypassed the "Wolf Clause" and joined hands with their American counterparts to explore space. At the 2017 Global Space Exploration Conference, it was reported that China Chang ‘e IV, which is scheduled to be launched in 2018, will fly to the moon with scientific loads from four countries, including the Netherlands and Germany, for scientific exploration.

  All these show that in the era of "global village" in which globalization is surging, China scientists conform to the development trend, actively participate in and vigorously promote international scientific and technological cooperation, and work together with international scientific and technological counterparts to make their own contributions to promoting their understanding of the world.

  "Big Science" Cooperation as the Guide

  Since you are involved, you should make greater contributions and play a greater role as much as possible. This is the principle that China has always adhered to in international scientific and technological cooperation and exchange. It’s not easy to do this, but scientists in China have found sufficient confidence from their practice in recent years. They have not only completed their own tasks, but also played a leading role in organizing some major international scientific projects.

  In April this year, the international cooperation project on human phenotypic research (one of the major international scientific projects, which is thought to crack the code of human birth, illness and death) entered the final stage before it was fully launched. The project was presided over by China scholars such as Academician of Chinese Academy of Sciences and Professor Jin Li, Vice President of Fudan University, with the participation of hundreds of global scientists. Previously, scientists from China have taken the lead in participating in some major international science projects. For example, the neutrino experiment in Daya Bay nuclear reactor stood out from eight experimental schemes around the world, and formed an international cooperative research team led by Wang Yifang, director of Institute of High Energy Physics of Chinese Academy of Sciences, and composed of 40 institutions from seven countries and regions around the world. In March 2012, the experimental team announced the discovery of a new neutrino oscillation, which won high recognition from the international physics community. Robert mckee Weng, a well-known American scientist, believes that this discovery can be said to be the most important physical (experimental) result from China.

  Known as "Artificial Sun", ITER is the largest international scientific and technological cooperation program in which China participates as an equal and full-fledged partner. Institute of Plasma Physics, Hefei Research Institute, Chinese Academy of Sciences is one of the important units of the China Working Group participating in this project. According to Wu Yu, director of the Applied Superconducting Engineering Technology Research Office of the Institute, most of the projects undertaken by China in this cooperation plan are related to superconductivity and power supply. At present, the large-scale superconducting conductor technology and quality system independently developed by China have passed the evaluation of international organizations, and the delivery of large-scale products has been completed for the first time in ITER plan, with 100% localization and 100% qualification rate. While participating in ITER construction, China scientists have begun to plan and build the future China nuclear fusion engineering experimental reactor. According to reports, the overall design scheme of the experimental reactor has been completed, and the pre-research work is currently being carried out. It can be predicted that China scientists will play a greater role and make more outstanding contributions in the international grand scientific plan of peaceful use of nuclear energy for human controlled nuclear fusion.

  Develop "step by step" in three periods.

  International cooperation and exchange is an inevitable requirement of opening up to the outside world in the field of science and technology. Under the background of globalization, the links between countries are getting closer and closer, and the importance of international cooperation and exchange in science and technology is becoming increasingly prominent. As Xu Guanhua, former Minister of Science and Technology, once pointed out, the motive force of scientific and technological development lies in the collision of different ideas and cultures. Through extensive and in-depth international exchanges and cooperation, fully absorb the wisdom and technological advantages of others, which is in line with the inherent requirements of the development of science and technology itself. In the new historical period, independent innovation should be based on the strategic idea of constantly expanding and strengthening international scientific and technological cooperation and making full use of global scientific and technological resources.

  Based on the analysis of researcher Cheng Ruyan of China Institute of Science and Technology Information, we can generally divide the development of international cooperation and exchange of science and technology in China into three periods since the reform and opening up.

  The first is the recovery period (1978-1985). The National Science Conference held in March, 1978 proposed "strengthening international scientific and technological cooperation and exchange", "inviting foreign scientists and engineering experts to give lectures in China" and "strengthening the scientific and technological research work of our overseas institutions". During this period, China determined the specific policy of international scientific and technological cooperation at this stage, adjusted the centralized management of scientific and technological foreign affairs, established the management system of talent introduction, and strengthened the scientific and technological research of foreign institutions.

  The second is the period of all-round development (1985-2000). 《1986— The Science and Technology Development Plan 2000 puts forward policies and measures to further strengthen international science and technology cooperation and technology introduction, and points out that it is necessary to further organize and formulate unified technology introduction policies and plans. During this period, the international science and technology cooperation policy further strengthened and standardized the technology introduction work; Strengthen the guidance and management of joint research and development institutions; Made a decision to actively join international science and technology organizations; Standardize the protection of intellectual property rights in international scientific and technological cooperation and exchanges.

  The third is the period of great leap (from 2000 to present). China has established the policy of "mutual benefit and win-win" and carried out international scientific and technological cooperation in an all-round, multi-level and wide-ranging way. During this period, the international science and technology cooperation policy showed four characteristics: promoting international science and technology cooperation from the national strategic level; Strengthen international scientific and technological cooperation and set up special funds for international scientific and technological cooperation; Actively participate in and take the lead in organizing the international big science and big project plan; Strengthen technical assistance to developing countries.

  The government and the people set each other off.

  According to Ye Dongbai, director of the Department of International Cooperation of the Ministry of Science and Technology, China’s international cooperation and exchange in science and technology has made great achievements in the past 40 years since the reform and opening up. He listed a series of relevant statistics. Up to now, China has scientific and technological cooperation relations with about 160 countries and regions, has signed more than 110 intergovernmental scientific and technological cooperation agreements, joined more than 200 intergovernmental international scientific and technological cooperation organizations, and sent about 150 scientific and technological diplomats to more than 70 foreign embassies and consulates around the world. China has opened nine innovative dialogue mechanisms with major countries and regions in the world (China-US, Central Europe, China-Germany, China-France, China-Israel, China-Pakistan (West), China-Russia, China-Canada, China and Belgium), and established six scientific and technological partnership programs with developing countries (China Africa, China ASEAN, China South Asia, SCO countries, Latin American countries and Arab countries), which basically achieved global coverage for developing countries.

  Ye Dongbai pointed out that China’s international scientific and technological cooperation and exchanges are unprecedentedly active. On the international stage, we have shown a positive and enterprising spirit and put forward new ideas, initiatives and plans for cooperation and exchanges. Committed to creating a new pattern of paying equal attention to "bringing in" and "going out" in international scientific and technological exchanges. With regard to the related work promoted this year, Ye Dongbai said that China will formulate country-specific cooperation strategies with Britain, Italy, Israel and other countries on the basis of the experience of publishing the German Strategy for Building the Future through Science and Technology Innovation in 2016. According to the plan, China-EU scientific and technological innovation cooperation will usher in several important activities, including the third China-EU innovation cooperation dialogue, the second China-France innovation dialogue, the deep docking between China and German Industry 4.0, and the docking cooperation between China High-tech Zone and Italian industrial clusters.

  While actively exploring and utilizing the traditional international scientific and technological cooperation and exchange platform, China is also building and building a new platform. The "One Belt, One Road" of "openness, tolerance, cooperation, co-construction and sharing" is undoubtedly one of the best platforms to benefit the scientific and technological innovation of countries along the route. At the summit forum on "One Belt, One Road" international cooperation held in mid-May, China announced the launch of the "One Belt, One Road" scientific and technological innovation action plan, and carried out four actions: scientific and technological humanities exchange, joint laboratory construction, cooperation in science and technology parks and technology transfer. It promises to arrange 2,500 young scientists to engage in short-term scientific research in China in the next five years, train 5,000 scientific, technical and managerial personnel, and put 50 joint laboratories into operation. Advocate countries along the route to strengthen cooperation in frontier areas such as digital economy and artificial intelligence, and promote the construction of big data, cloud computing and smart cities.

  Promoting non-governmental scientific and technological cooperation and exchanges between China and foreign countries is an important dimension of China’s scientific and technological opening up. China Association for Science and Technology, as a mass organization of scientific and technical workers in China, has intensified its efforts in recent years to support and help China scientists to participate in international scientific and technological organizations and hold posts, and to support and encourage the Society to hold a series of meetings of high-level international organizations in China. At the level of various enterprises, a large number of Chinese and foreign scientific and technological workers have gone abroad and realized transnational flow, which not only deepened cultural exchanges, but also promoted innovation and entrepreneurship.

Is there any place to accommodate the fitness fever suppressed by the epidemic?

  Xinhua News Agency, Beijing, May 10 th Question: Is there any place to accommodate the fitness fever suppressed by the epidemic?

  — — One of the series of national fitness surveys

  Xinhua news agency reporter

  After more than three months, Cui Ke, who lives in Beijing, finally played a ball.

  "I’m exhausted," said Cui Ke, 42. However, speaking of his own assists, I can feel his pride and satisfaction through the phone. "I still prefer outdoor exercise, but I can’t display it at home, and I am always afraid of disturbing my neighbors."

  The sudden outbreak of COVID-19 has made people retreat from outdoor to indoor. Many people, like Cui Ke, follow the online tutorial to exercise at home every day, but deep down they still miss the comfort and carefree of calling friends and sharing sweat under the sunshine and breeze.

  With the relief of the epidemic, outdoor fitness facilities that have been cold for a long time are gradually becoming more and more lively, and the contradiction between supply and demand of outdoor fitness facilities that was temporarily covered up by the order of staying at home will reappear. This epidemic situation makes people feel the importance of health, fitness and immunity more and more. Obviously, after the epidemic situation, people will put forward higher requirements for the quantity and quality of fitness places. Before and after the epidemic, Xinhua News Agency reporters conducted in-depth research in Shanghai, Tianjin, Suzhou and other places, and also referred to some foreign experiences in developing mass sports, hoping to promote the better development of national fitness.

  Epidemic surprise stimulates home fitness fever

  In the leisure time at home, more and more people put down their mobile phones, take a step and join the army of sweat for health. The 25-year-old Shen Yutao is such a "fitness newcomer" who cultivated exercise habits from scratch after the epidemic.

  "Before, because of the tight work rhythm, long-term sedentary and irregular diet, I gradually felt that my figure was out of shape, and my physique was gradually declining, which made me easy to get sick," said Shen Yutao, who is engaged in consulting industry.

  After working at home during the epidemic period, Shen Yutao started his own fitness plan, taking regular exercise with reference to the tutorials on fitness software, and taking a rest every two days.

  "By persisting in exercise, my physical condition has obviously improved, and persistent completion of the set goals is also an improvement to my personal spiritual level." Shen Yutao said that after the epidemic, he plans to start running and fitness.

  According to the data provided by the fitness software Keep, during the epidemic, the average duration of user exercise was 36.2 minutes each time, nearly doubling compared with 2019. The cumulative coverage of sports live broadcasts launched by Keep in conjunction with many institutions and fitness experts exceeded 56.5 million.

  Li Xinyan, general manager of Keep, said that in the short term, there may be large-scale "fresh air" behavior after the epidemic. Everyone has been at home for a long time and wants to go out and move. People’s demand for home sports will decrease, but the demand for outdoor sports will increase. But in the long run, people’s online exercise habits will continue during the epidemic, and regular exercise will be the norm.

  Zhong Bingshu, president of the Capital Institute of Physical Education, also said that the sudden epidemic has given people a vivid lesson, and the change of health awareness will inevitably bring about an increase in fitness demand. However, he also said that home fitness is a special state that has to be done during the epidemic. On the one hand, the area available for fitness exercise in the home is very limited; On the other hand, participating in fitness activities is also one of the important means of interpersonal communication, which cannot be achieved by home exercise. Therefore, outdoor fitness and gym fitness will remain the mainstream after the epidemic, and home exercise can only be a supplement to people’s fitness methods.

  Docking the "last mile"

  Being at home is a special state during the epidemic. It is also in this special environment that office workers like Shen Yutao get regular fitness conditions. After the epidemic is over, people’s life rhythm will become faster again, and their free time will be reduced. The adherence to fitness habits needs to be supported by convenient venues and facilities.

  At the end of 2019, Xinhua News Agency reporters found in various places that many cities are making use of various "Jinjiao Silver Borders" in the core areas of cities to build fitness facilities, connecting the "last mile" of fitness venues and providing convenience for people’s fitness. This is also emphasized and advocated by many documents of the State Council.

  Suzhou Shishan Hengtang Street Recreation and Sports Badminton Center, which has 14 badminton courts and 5 table tennis courts, was converted from a former factory building. The center is located in the core area of Suzhou High-tech Zone, but the street clearly defines the service purpose of "giving priority to public welfare" to benefit the people. From 7: 00 to 9: 00 in the morning, it is open at the low price of 5 yuan per person, and the opening price at other time periods is also lower than the market price. The street also holds regular table tennis and badminton events based on the venue to increase the sense of participation and gain of the fitness crowd.

  "After the factory is recovered, it will become idle assets. What we have to do is to integrate idle assets and solve the problem of where people go to exercise." Liu Lan, stationmaster of Hengtang Street Cultural and Sports Station in Shishan, said, "The operation effect is still very good. People in the basic nearby areas will come here, and the venue is often full."

  Despite the cold winter, Qujiang Park in Tianjin is still very lively. The ball field is full of fitness people, and the fitness equipment room is also full of laughter.

  Qujiang Park was originally an ordinary city park, but after the transformation in 2018, except for squares, green spaces and trails, all kinds of fitness venues and equipment in the park are already full. According to Lou Yueguang, deputy director of the Sports Bureau of Hexi District, Tianjin, it is difficult to build a fitness center in the community because there are many old residential areas nearby, so transforming the park is the most feasible scheme. When the government invested in the renovation, various sports venues and facilities were added to meet the diverse fitness needs of the surrounding residents.

  Under the viaduct along Fuxing River in Hexi District, the cage basketball court between piers has become a small world for basketball lovers. The basketball court covers a small area, but it is a perfect use of space, which does not hinder traffic and can shelter from rain and snow.

  According to Wang Bing, president of Hebei Yonghuai National Fitness and National Health Development Research Institute, the fitness venues around these people are the best embodiment of the people-centered concept of national fitness work. Wang Bing believes that the construction of fitness facilities should pay attention to demand investigation, and the concept should be changed from "what I want to provide" to "what the people need" according to the principle of "according to the need, time and place".

  Create a fitness online celebrity according to local conditions

  By the Huangpu River, the morning light outlines the city’s skyline. On the riverside trail, in addition to tourists who take pictures, there are runners who try to adjust their breathing. Seizing the opportunity of Shanghai to promote the cross-strait connection of Huangpu River and the transformation of riverside coastline, Shanghai Sports Bureau took the lead in transforming the abandoned factory buildings in Yangpu District into public sports centers. Fitness trails, basketball courts and skateboarding venues & HELIP; … More than 20 sports venues scattered along the river have revitalized the once ruined industrial remains.

  There are light stadiums that can be scanned at any time, fitness stations that provide free direct drinking water and change clothes and storage functions, rest areas equipped with defibrillators and professional emergency personnel, and artistic spaces and landmark landscapes for the transformation of industrial remains. The river breeze blows gently, the lights flash, history and fashion meet, and the fitness venue blends with the scenic spots in online celebrity. In the words of Zhao Guangsheng, deputy director of Shanghai Sports Bureau, "the industrial rust belt of the past has become the life show belt of today".

  Also welcoming the "gorgeous turn" is the old railway around the city in Tianjin. The abandoned railway section in Hexi District has been transformed into a greenway park, and the original rail line has been transformed into a fitness trail nearly 5 kilometers long.

  "There was no place to go (exercise) when there was no trail. Now I come here two or three times a day, once in the morning and once in the afternoon in winter, and I also go out for a walk in the summer evening, "said Uncle Cui, who lives in a nearby neighborhood. Because it is next to a residential area, people come and go on the trail, which is very lively.

  Greenway Park retains the theme style of the railway, and the landscape design of platforms, bus stops and tracks makes people vaguely feel the elegance of the railway around the city in the past, which makes this fitness center reflect some cultural and historical details. Fitness venues and recreational facilities suitable for people of different ages have turned this once freight artery into a new urban landscape that gathers popularity.

  Wang Hong, deputy secretary of the Party Group of Tianjin Sports Bureau, said that the transformation of the ring railway in other areas of Tianjin will continue in the future, and the ultimate goal is to build a fitness greenway circle integrating fitness, leisure and sightseeing functions on the basis of the old railway, making it a "city necklace" of Tianjin.

  Suzhou’s fitness trail around the ancient city river is 16 kilometers long, which is an important part of China’s Grand Canal cultural belt, a world cultural heritage, and also a livelihood project for citizens to relax and exercise and tourists to experience Soviet-style life.

  Along the trail, a physical fitness test and exercise guidance station, a fitness Little Square and a fitness path are set up, so that people born by the water can move according to the water and enjoy being near the water. On the sports culture billboards erected at intervals, you can hear Wu Nong’s nursery rhymes with the theme of sports games as long as you scan the code on your mobile phone, so that pedestrians can appreciate the Millennium culture of Wudi.

  For a long time, the construction of fitness venues in China has lagged behind. Inadequate venue facilities and unreasonable distribution have become a short board that restricts the development of national fitness. However, the practices in Shanghai, Tianjin and Suzhou show that grounded and popular fitness venues can not only be integrated into the blueprint of urban development, but also become a bright color to highlight the cultural features of the city, so that people can enjoy it and make the city beautiful.

Foreign media: North Korea’s Fengxili nuclear test site is showing signs of restarting, and the satellite found traces of cars passing by.

Fengxili nuclear test site

  After North Korea announced a "major" test last weekend, American commercial satellites recently found signs of restarting the Fengxili nuclear test site abandoned by North Korea last year.

  South Korea’s "Central Daily News" quoted the US North Korea website "38 North" as saying on December 11 that "traces of cars and people passing by were found at the Fengxili nuclear test site", saying that "the tunnel area closed by the nuclear test site has not been observed before, but in the photos taken between November 18 and December 7, you can see traces of cars passing by and footprints of people on the snowy road".

  38North said, "It is still impossible to judge the significance of these activities, but at least it can show that North Korea may have left some personnel at the nuclear test base as it did in March this year." The media also said in March this year that "some slight footprints were found around the closed tunnel area, but no reconstruction trend was found at the scene". However, only footprints were found in March this year, but now there are traces of cars passing by. The situation is slightly different.

  The Central Daily News reported that from these slight signs, it is still impossible to judge that North Korea is restarting its nuclear test base. However, the South Korean authorities believe that North Korea can complete the restoration of the nuclear test site within weeks or months.

  In April 2018, North Korea decided that it would suspend its nuclear test and intercontinental ballistic missile launch test from April 21 of the same year, and it would abandon the Fengxili nuclear test site in northern North Korea.

  On May 24, last year, North Korea blasted several tunnels in the test site and dismantled related facilities, officially announcing the abandonment of the nuclear test site. According to Xinhua News Agency, an international press group composed of 10 overseas media reporters from China, Russia, the United States, Britain and South Korea covered the demolition activities at the scene.

  However, since the breakdown of the "Golden Specialist Meeting" in Hanoi in February this year, the denuclearization negotiations between the DPRK and the United States have reached a deadlock. In April this year, Kim Jong-un, the top leader of North Korea, limited himself to the end of the year and asked the US to come up with a new constructive plan in line with the interests of both sides. Otherwise, North Korea will take a new path.

  On December 8, North Korea announced that it had successfully conducted an "extremely significant test" at the Xihai satellite launch site. North Korea did not disclose the specific content of the test, but it is speculated that it may involve intercontinental missile engine technology. The outside world is worried that North Korea may restart intercontinental missile tests and other activities at the end of the year. (Reporter Nan Boyi)

Hot Search: A Great Anti-cyber Violence Movie.

 Author: Hu Jianli

The film "Hot Search" tells the story behind a "girl’s bullying on campus" incident. By launching an online public opinion war, the heroine finally reveals the criminal truth of the real abuser, which not only has ups and downs and many reversals, but also reveals how online public opinion is incited and used.

In the current complex network public opinion environment in China, the release of this film is just the right time, which well reflects the presence and timeliness of film and television works, has a strong social practical significance, and has a warning effect on the majority of netizens. It is a realistic genre film with novel ideas and thought-provoking.

In 2013, Xin Yukun, a 29-year-old young director, won the Best Director Award at the 8th FIRST Youth Film Festival and the Best New Director nomination at the 51st Taiwan Film Golden Horse Award for his blockbuster suspense film Heart Maze. In 2017, the crime suspense film "Burst Silent" directed by him also enjoyed a good reputation, with 8.2 points for Douban and 54.25 million yuan at the box office.

In the above two films, Xin Yukun showed his exquisite multi-line circuitous narrative ability and unique cold realistic image style. Hot Search is the third cinema film directed by him independently, which also has suspense and criminal elements. The difference is that the story takes place in contemporary China metropolis, focusing on hot social topics such as online public opinion, online violence and sexual assault, which is more likely to resonate with young audiences.

This time, Xin Yukun took the initiative to change the theme and background of the story, and adopted a typological narrative technique that was more in line with the aesthetics of ordinary audiences. He told a story that was not very complicated, which was exciting and full of twists and turns, and was quite ornamental and topical, showing his strong narrative ability as always.Compared with the previous two works, Hot Search is a mature commercial film, but the background color of sharp observation of social reality and concern for vulnerable groups has not changed.

At the beginning of the film, Chen Miao, the editor-in-chief of the media played by Zhou Dongyu, published an explosive article on "Girls’ Campus Bullying" on the large-scale operated by his team, and also talked proudly about the skills of inciting online public opinion at the pre-editing meeting: "If netizens want to scold Zhang Xiaosui, we will provide scolding points". Unexpectedly, the girl Zhang Xiaosui committed suicide by jumping off a building after encountering cyber violence. Before jumping off the building, she sent a letter to Chen Miao to explain the hidden feelings. Chen Miaocai knew that she had been accidentally used as a gun. Although she had a desire for traffic and an ambition to become bigger and stronger from the media, she was a media person with conscience at heart. In order to make amends and get justice for Zhang Xiaosui, with the help of her colleagues, she burned her bridges and launched a just online public opinion war with Justin.

The framework of the whole story is not complicated, but the advantages are full and vivid details, exquisite narrative techniques, foreshadowing from time to time, and even sharp contrast between the hero and heroine, leaving some suspense until the last moment. Although it is not difficult to guess, because the focus of this film is not to create a suspense atmosphere, it enhances the drama and appreciation of the film.

Through the superb typological narrative skills presented in Hot Search, Xin Yukun once again proved himself to be a master narrator among the new generation directors in China, who can not only tell complex stories clearly, but also tell simple stories twists and turns.

Although Hot Search is a commercial film, it has a sharp observation and vivid description of the current chaos of online public opinion in China, showing reflection on online violence, criticism of those who are rich and heartless, and sympathy for the vulnerable groups.

In recent years, some plots in TV series, such as The Beginning and Imperfect Victims, have expressed and reflected on the phenomenon of cyber violence. However, on the big screen, except for a film "Search" directed by Chen Kaige in 2012, few works with this theme have met the audience. "Hot Search" can be called the most complete, complete and profound domestic film that shows the chaos of network public opinion and the phenomenon of network violence so far, and it has great social practical significance.

The film describes in detail the whole process of Chen Miao’s self-media and the investors behind it inciting and using online public opinion, and shows the audience the complete processing process of "hot search" one after another, which has a certain behind-the-scenes nature.

In the film, as an influential editor-in-chief from the media, Chen Miao’s mantra when she first appeared was "There are hot spots that cannot be ignored". In order to attract fans’ attention and reading, and win investors to increase investment, she broke the news about the video with ulterior motives, deliberately incited speculation without investigation and verification, and concocted the topic of "girl bullying on campus" into a hot search, which triggered cyber violence against Zhang Xiaosui, a girl who was pushed by netizens. Unexpectedly, as Zhang Xiaosui committed suicide by jumping off a building, online public opinion reversed, and netizens began to accuse Chen Miao of eating "human blood steamed bread" from the media. Chen Miao had a brainwave and quickly came up with a new trick: throwing a pot at a swearing netizen, interviewing Zhang Xiaosui’s mother, and using the video of the other side’s tears, not only earned another wave of traffic, but also successfully washed himself.

The wolf has a winning game when the shepherds quarrel. Chen Miao’s self-media farewell concoction of hot search and harvest traffic is just a pawn of the boss of the investor behind it, and Chen Miao is still complacent when he is shot by others. Subsequently, Chen Miao launched an online public opinion war with the other party to uncover the truth. The two sides constantly broke the news, and the public opinion reversed several times. Justice was once forced to the rescue …

The online public opinion war described in Hot Search not only makes the audience who are not familiar with online hype look thrilling, but also makes everyone alert: sometimes the so-called facts you see online are not necessarily the facts, and the so-called truth you see is not necessarily the truth. Each of us should maintain the ability of independent thinking, be objective and rational when speaking online, and don’t become an accomplice of cyber violence.

One of the most heartbreaking news in the first half of this year was that a primary school student in Hubei was knocked down by a car and killed. In the process of seeking advice from the school, his mother was attacked and insulted by some netizens because of her good image and elegant dress. In the end, the distraught and unbearable mother committed suicide by jumping off a building at the first seven hours of her child.

How to make the cyber violence that Hubei’s mother encountered before her death not happen again? How to make the cyber violence that Zhang Xiaosui encountered in the film not repeat itself? The film "Hot Search" has played a very good role in alerting the majority of netizens. I hope everyone can learn from it, consciously oppose cyber violence and jointly create a clean and tidy network public opinion environment.
