Take stock of those unexpected events in previous Olympic Games.

  The 2020 Tokyo Olympic Games was postponed for one year due to the COVID-19 epidemic.

  Take stock of those unexpected events in previous Olympic Games.

  Wu Bingcong

  If it weren’t for a raging COVID-19 epidemic, the 2020 Tokyo Olympic and Paralympic Games would be in full swing. The virus pandemic forced the Tokyo Olympic Organizing Committee to postpone the Olympic Games for one year, but this is not the first time in history that the Olympic Games cannot be held as scheduled. Due to the two world wars, several Summer Olympics and Winter Olympics in Berlin, Germany, Tokyo, Japan and Helsinki, Finland were forced to cancel. In addition to the COVID-19 epidemic, Norovirus and Zika virus have also brought great trouble to the organizers of the Olympic Games.

  As a four-year world sports event, the opening ceremony of the Olympic Games and the flame lighting ceremony have attracted much attention. However, accidents such as the burning of pigeons in the Seoul Olympic Games and the "five rings without one ring" in the Sochi Winter Olympics have caused a lot of controversy and discussion. The Olympic Games symbolizes peace, but it happened that some people took the opportunity to stir up terrorism, maim innocent lives and arouse people’s panic. The unfortunate casualties of athletes and behind-the-scenes workers also made everyone feel sad. Taking stock of these sudden accidents in the course of the century-old modern Olympic Games has brought many challenges to the organizers, but peace and beauty are undoubtedly the main theme of the century-old Olympic Games.

  Wars broke out, and the Tokyo and Berlin Olympic Games were cancelled.

  Before the official announcement of the Tokyo Olympic Games was postponed, the International Olympic Committee gave a four-week observation period, and was finally forced to make a "difficult decision" to postpone it according to the epidemic situation. For the organizers, the delay of this major event has brought immeasurable economic losses. The BBC reported that in addition to the $11.8 billion already invested, the organizers are bound to need more funds, and sponsors, tourism, urban planning, historical heritage and local enterprises will all suffer from the negative impact of the postponement of the Olympic Games.

  The most famous cancellation of the Olympic Games in history also happened in Tokyo, Japan. If we sort out the bidding process of the 12th Olympic Games, we will find that it was a group of people who tried their best to host the Games and then tried their best to sayno..

  Writer David goldblatt recorded in his book "Games: A Global History of the Olympics" that the Japanese government at that time actively bid for this Olympic Games, hoping to show a Japan that recovered from the 1923 earthquake disaster. The Tokyo government formally applied in 1932, and Rome, Italy and Helsinki, Finland competed for the right to host the games at the same time. David goldblatt describes in his book that the Japanese government lobbied around to win the right to host the games, and finally persuaded Mussolini. The book wrote: "At that time, you helped me and I helped you, which has become a normal state of international sports. Mussolini surprisingly announced that if Japan supports Italy’s bid for the 1944 Olympic Games, Italy will support Japan’s bid for the 1940 Olympic Games. "

  In July 1938, the Japanese government suddenly issued a statement saying that the Olympic Games would not be held! The Japanese Olympic Committee euphemistically mentioned "the trouble with China" in its statement. In fact, there are two reasons for the cancellation of this Olympic Games: First, after the September 18th Incident, Japan’s aggression against China was condemned by the League of Nations, the predecessor of the United Nations. After Japan withdrew from the organization in 1933, it began to expand its aggression around the world, and gradually became hostile to all countries in the world and fell into diplomatic difficulties. Second, there are voices in Japan, hoping to spend more money on military activities instead of hosting the Olympic Games. Under such pressure, the Tokyo Olympic Games and the Sapporo Winter Olympics planned for the same year were all cancelled.

  Subsequently, the International Olympic Committee decided to change the venue of the 12th Summer Olympic Games to Helsinki from July 20th to August 4th, 1940. However, due to the chaos and turmoil in Europe caused by World War II, the Olympic Games and Winter Olympics, which changed hands, were forced to cancel again. Finally, after the end of World War II, the Olympic flame was reignited in London in 1948. After Japan gave up the right to host the Olympic Games in 1940, it was as far away as 1964 that it ushered in the Olympic flame again.

  The earliest cancellation of the Olympic Games took place in Berlin, Germany in 1916. The German Stadium in Berlin, which was built for the Sixth Olympic Games, started construction in 1912, and when it was completed in 1913, 10,000 doves were released, and 60,000 people watched the event. However, a year later, World War I broke out, and the war lasted for several years. In serious cases, the German army even advanced to 70 kilometers away from Paris, ioc headquarters. Wars broke out, peace ceased, and the Olympic Games, a symbol of peace, died unfortunately in the war. Even ioc headquarters once moved to Lausanne, Switzerland, a neutral country, to take refuge.

  Coubertin, the father of the modern Olympic Games, took "creating a sports culture that exists without politics" as his lifelong goal. However, the Olympic Games are frequently associated with war and even aggression, which makes people feel sorry. Peace and development are the themes of today’s era, but the cancellation of these Olympic Games in history has witnessed the dark history of imperialist aggression in the form of sports.

  Human life is a matter of concern, and the Olympic casualties are embarrassing.

  In every Olympic Games, there are always several happy families and several worried families. Some athletes break through the limit to win the gold medal, but others are injured or even killed.

  The latest death of an athlete occurred at the Paralympic Games in Rio de Janeiro, Brazil in 2016. Bahman Goba Nezhad, a 48-year-old Iranian cyclist, crashed on the way to the men’s C4-5 cycling road race and died after being sent to hospital for treatment. Goba Nezhad is a veteran of the battlefield, with 12 years of cycling experience. He also participated in the London Olympic Games in 2012, and was called the best national player by Iranian Paralympic Committee Secretary-General Ashrafi.

  However, the veteran accidentally crashed on the winding downhill road around the mountain road. After falling, his head hit the rock. On the way to the hospital, he had a heart failure and eventually died. After the accident, the Brazilian Olympic Committee informed the families of the deceased and arranged for the remains to be transported back to their hometown for burial. The International Olympic Committee later issued an accident investigation report. The BBC reported that the death of Goba Nezhad was the first time that an athlete died during the Paralympic Games since it was held in 1960. To this end, the organizers joined the flag at half-mast and a mourning ceremony at the closing ceremony to pay tribute to the late athletes.

  Athletes are the protagonists in the Olympic Games, but the behind-the-scenes workers in the process of preparing for the Olympic Games are also worthy of attention. During the preparation for the Olympic Games, the host country often commandeers a large amount of manpower. When the Olympic Games cycle meets the venue’s rush, the casualties caused by overtime and overwork are also very worrying.

  In July 2019, the Tokyo Olympic venues were under construction, and the heat wave in midsummer swept through Tokyo. Reuters reported that since the end of July, 2019, the soaring temperature has caused 57 deaths in all parts of Japan. At this time, construction workers are facing great challenges in working outdoors.

  At the beginning of August, the Tokyo International Exhibition Hall was renovated as planned and prepared to be used as a media center after the opening of the Olympic Games. On the afternoon of the 8th, a 50-year-old construction worker was found unconscious when laying a cable outside. He eventually died of heatstroke.

  In addition to the potentially fatal working environment, high-intensity work pressure is also terrible. In March of that year, it was revealed in the media that a 23-year-old Japanese construction worker slept only two or three hours a day on average in order to build the Olympic venues in Tokyo, and was overwhelmed physically and mentally. Finally, he committed suicide three months after joining the Olympic venues construction plan. In the suicide note, he said: "My physical and psychological condition has reached the limit, and I can’t think of any other way to solve it."

  The accident attracted the attention of Japanese Minister of Health, Labor and Welfare Yasuhisa Shiozaki, who said that the incident was so serious that the organizers could not tolerate any fatal accidents at the Olympic venues and would start to reduce the workload of workers. At the same time, Dacheng Construction Company, which undertakes the building improvement plan, also publicly admitted that the company did not abide by the labor management contract and violated the Japanese Labor Basic Law.

  Harm the innocent when a peaceful event is attacked by terrorists.

  The Olympic Games has gathered politicians from various countries and top players in the sports field, and a large number of tourists have gathered in the city. It is inevitable that terrorists will take the opportunity to make trouble and kill innocent people in order to achieve political demands.

  The bombing of the Centennial Olympic Park was a terrorist incident that had to be mentioned during the Olympic Games. The case occurred on July 27th, 1996, during the Olympic Games in Atlanta, USA. The explosion was deadly, causing one death, one heart attack and 111 injuries.

  Eric Rudolph, the head of terrorism, has long been dissatisfied with the Clinton administration’s position on abortion. In order to create momentum, he is determined to make the Olympic Games impossible. The bomb was quietly installed in the Centennial Olympic Park in Atlanta. Fortunately, security guard Richard Jurville found a bomb ahead of time and evacuated most of the audience, which reduced the number of casualties. But at first, this conscientious security guard was once suspected by the FBI. Fortunately, the truth was finally found out, and Rudolph was also sentenced to life imprisonment in 2005.

  In Munich in 1972, when the 20th Summer Olympic Games was held in West Germany, the Palestinian armed group "Black September" targeted the Israeli delegation participating in the Olympic Games. At 4: 10 in the morning, eight "Black September" armed men sneaked into the residence of Israeli athletes in the Olympic Village, two doors were pried open, weightlifter Roman and wrestling coach Weinberg were shot dead on the spot, and nine other members of the delegation were also held hostage.

  This incident led to the emergency suspension of the Olympic Games, and negotiations and hostage rescue operations began. The Palestinian-Israeli conflict has a long history. Black September hopes to demand the release of 234 Palestinians held by Israel through its hostages. Israel refused, but both sides agreed to take Egypt as an intermediate country to negotiate the redemption of hostages. At that time, the rescue plan given by the former West German police was to rescue the hostages when Palestinian militants left the country by replacing passenger planes from the air base. However, due to the wrong information, the police underestimated the number of armed personnel, and the crew of the passenger plane did not cooperate properly, which led to the rescue plan being completely out of control. In the 45-minute battle, all the hostages were killed, five of the eight Palestinian militants were killed and three were arrested; In a hijacking incident in the same year, the former West German government handed over the three men to Libya for release.

  On September 6, 1972, the Munich Olympic Games, which was interrupted for 34 hours, continued, and a memorial ceremony was held for the Israeli delegation. The 12 seats vacated during the ceremony represented 11 members of the Israeli delegation and a former West German policeman who died unfortunately.

  In an awkward moment, the opening ceremony will fall off the chain.

  In addition to the wonderful competition, the most eye-catching performances in each Olympic Games are the grand opening ceremony and the flame lighting ceremony. Outside the scene, there are countless viewers watching the performance with jet lag in front of the TV, and any unexpected situation on the scene will be broadcast in high-definition pictures and spread all over the world.

  In 1988, the flame burned a dove of peace at the opening ceremony of the Seoul Olympic Games in South Korea, which attracted the highest attention in history. This accident was even crowned as "the most cruel opening ceremony in the world". In order to show the peaceful and beautiful intention with white pigeons, the organizer has prepared 2,400 white pigeons, and plans to release them at the opening ceremony of the Olympic Games. The scene of the pigeons spreading their wings in Qi Fei is very shocking. However, what I never expected was that on the day of release, some pigeons took off and saw the pillars or towers in the stadium and flew to rest.

  In the following flame lighting session, three torchbearers, Sun Meiting, Zheng Shanwan and Jin Zhuoyuan, took the lifting platform and lit the flame in Taichung with their arms raised high. At this time, the torch platform is more than ten centimeters above the torchbearer’s head, and no one can see dozens of white pigeons resting on it. At the moment when the flame was lit, the white dove that had no time to fly away was buried in the sea of fire, and the audience exclaimed. Afterwards, both the torchbearers and the Organizing Committee were condemned by animal protection organizations. However, due to their location and time, the torchbearers were unable to drive away the pigeons and could only watch the tragedy happen.

  Due to planning mistakes, the dove of peace at the Olympic Games turned into a "roasted pigeon". Although the tragedy could not be redeemed, this painful historical memory remained in the hearts of a generation of Koreans. A few years ago, in the popular Korean drama "Please Answer 1988", the protagonist, who was an Olympic volunteer, was designed to take the burned dove home for burial, and remember this history with images.

  The opening ceremony of the 2014 Winter Olympics in Sochi, Russia, was also accidentally broken, and only four rings appeared in the Olympic rings. The most important symbol of the Olympic Games is wrong, which is a big mistake in the history of the Olympic Games for a hundred years.

  At the end of the opening performance of "The First Impression of Russia", the Olympic rings decorated with five edelweiss lit up the night sky. However, due to technical failure, the ring in the upper right corner of the screen disappeared out of thin air. The applause at the scene was sparse, and the audience also found this mistake. However, in the official TV broadcast pictures of countries around the world, the audience still saw the complete five rings. In this regard, Ernst, the chief producer of the opening ceremony, said that because there was a delay in the broadcast of the picture, they used the restoration technology to make up for this shortcoming. Although the rescue was fast enough, the outside world did not stop, because in the previous countdown of 10 seconds, the picture fell into darkness from the fifth second, and this obvious mistake made the scene look very embarrassing.

  In the face of frequent technical problems in the opening ceremony, Ernst believes that in the only three-week rehearsal time, it is necessary to train actors and deal with equipment, and it is inevitable that mistakes will be made in a hurry. He felt that even if there were mistakes, the Sochi Winter Olympics still presented a wonderful opening ceremony performance for the world.

  When the virus hits Zika and Norovirus, the lethality is not small.

  Before Covid-19 delayed the Tokyo Olympic Games, the 2016 Rio Olympic Games in Brazil and the 2018 PyeongChang Winter Olympics in South Korea were also threatened by Zika and Norovirus respectively. Fortunately, the number of people infected with the virus was limited and properly controlled, and the Olympic Games was finally held successfully.

  The opening ceremony of the Rio Olympic Games is scheduled to be held on August 5, 2016. However, according to the BBC, only three months ago, 125 internationally renowned scientists and doctors from Harvard, Oxford, Yale and other academic institutions jointly requested that the Olympic Games to be held in Rio de Janeiro be postponed or changed to other regions.

  In this open letter to the World Health Organization, scientists said that it was "immoral" to hold the Olympic Games at this time because of the rampant Zika virus. Zika virus is spread by mosquito bites. It started in Brazil and spread to more than 60 countries in more than a year. Scientists pointed out that although the symptoms of Zika virus infection are relatively mild, it may cause fetal malformation and microcephaly, and the consequences are quite serious.

  These scientists even said rudely that Brazil’s plan to kill mosquitoes was not successful, and the capacity of the country’s medical system was weakened. At this time, it was unnecessary to let about 500,000 members of delegations and tourists go to Brazil.

  However, in mid-June, the International Olympic Committee still decided to hold the Rio Olympic Games as scheduled. Through the assessment, the Olympic Committee believes that the virus has a weak impact on people other than pregnant women, and WHO points out that the mosquito activity in Brazil has been relatively small since August. Although the virus is identified as "low risk", experts still advise tourists to take preventive measures to avoid being bitten by mosquitoes.

  The virus also caused many athletes to retreat before the game. American cyclist Van Gadlen withdrew from the Olympic Games because of his fear of his pregnant wife and unborn baby. Pau gasol, a famous Spanish basketball player, also said that he would consider freezing sperm in advance before taking part in the Olympic Games.

  When the PyeongChang Winter Olympics was held in 2018, Norovirus was also a threat: it raided the Olympic Village one week before the opening ceremony on February 9, directly threatening the health of competitors from all over the world. The news that 86 guards in the Olympic Village were diagnosed with Norovirus broke out like a bolt from the blue. The organizers responded immediately. On February 6th, more than 1,200 guards evacuated from their posts were quarantined, and 900 gendarmes were urgently transferred to manage 20 Olympic venues and Olympic villages.

  Norovirus has aroused great concern because it is super contagious. This virus that causes non-bacterial acute gastroenteritis causes diarrhea and vomiting, and saliva, feces, food and water may be the carriers of virus transmission. The gangwon Institute of Health and Environment immediately began to investigate and detected the virus in many places in the youth training center near the Olympic Village, including drinking fountains, bathrooms, hand washing tables and so on.

  Fortunately, the organizing committee responded quickly, providing soap and disinfectant to players from all over the world, closing public drinking fountains, and announcing to avoid eating fresh food. Although the virus did not spread on a large scale, two Swiss freestyle skiers and three foreign journalists in the news center were still infected. Fortunately, although Norovirus attacked the Olympic Village, it was not fatal, but a series of infection symptoms made patients very uncomfortable.

Return to Tangshan in 1976 —— Commemorating the 40th anniversary of Tangshan Earthquake

  Tangshan, China, July 28 (Reporter Guo Xiangyu, Xiao Yuan and Du Zhen) According to the Voice of China report, today is the 40th anniversary of the Tangshan earthquake. Forty years ago, Tangshan, Hebei Province, took the lives of 240,000 people in just 23 seconds, and made this industrial city an island for 15 days after the earthquake.

  Li Shengtang, then deputy director of the dispatching room of Tangshan Airport, and Li Yulin, vice chairman of the trade union in Tangshan Mining Area of Kailuan Coal Mine, were both survivors of the Tangshan earthquake. When the earthquake occurred, they went to Beijing from the air and the ground respectively to ask for support from the central government.

  The earthquake shattered their families and changed their life trajectory. After a lapse of 40 years, every moment of the earthquake, help and disaster relief is still fresh.

  On July 27, 1976, in Tangshan that night, the weather was particularly sultry and the sky was surprisingly bright. Li Shengtang, then deputy director of the dispatching room of Tangshan Airport, recalled that his wife thought of the earthquake at that time. "My wife told me, oh, is there going to be an earthquake? I’m afraid she can’t sleep, so I said, don’t dream, it’s so hot in summer. “

  At the same time, Li Yulin, vice chairman of the labor union in Tangshan mining area of Kailuan coal mine, just rose to the well and worked underground for two days and one night. After returning home, he was so tired that he didn’t even eat, so he fell on the bed.

  At 3: 42 am on July 28th, the earth shook. Li Shengtang, who survived, climbed out of the ruins, held a pair of children under a tree in the yard and turned and ran to the airport dispatching building 1 km away. However, the damage of the airport made Li Shengtang almost desperate. Four of the eight pillars of the dispatching building were broken and the command system was completely paralyzed. Li Shengtang and his comrades searched the whole station and only found a barely usable ultrashort wave radio station.

  Li Shengtang recalled: "There is only one navigation station left. What’s wrong with the air station, the fixed tower and the antenna? There are two planes. Li -2 plane can fly in complex weather, but later it was found that the communication car was still working, and the back was broken, so it could be sent out, and it could generate electricity. “

  Kailuan coal mine. Li Yulin was in a hurry to get to the mining area, and he was worried about the underground workers whose life and death were unknown. Standing on the dark mine and shouting, the only people who can respond to Li Yulin are Cao Guocheng, director of the Armed Forces Department, Yuan Qingwu, the winch driver of the electromechanical department, and Cui Zhiliang, the driver of the mine rescue team. The only equipment that can be found is a mine ambulance that was not damaged by the earthquake.

  To Beijing! Report to the CPC Central Committee! This was the only way that Li Yulin could think of at that time. "The concept of going to Beijing came into being in the process of running from my home to the mine. All I saw was ruins and nothing else."

  Thirty minutes after the earthquake, the red mine ambulance sounded the alarm, carrying four people, including Li Yulin, from the mining area and heading west to Beijing.

  Asking for support from the central government is also the first thought in Li Shengtang’s mind. When he was about to start the radio station to guide the plane to fly to Beijing, he was held down by his comrades: taking off without approval is a violation of discipline.

  After the earthquake in Tangshan, it began to rain, and Li Shengtang finally made a decision. After the earthquake, the first distress plane flying to Beijing rushed out of the runway and took off in the rain without a navigation platform and only under the naked eye command of Li Shengtang.

  Li Shengtang said: "This is a special take-off in an extraordinary period. I asked the dispatcher to let the plane take off. In this way, it took off at 6 o’clock. "

  When Li Yulin’s car arrived in Beijing, the Li -2 plane under the command of Li Shengtang also landed smoothly at Nanyuan Airport. Two cars galloped towards each other in the streets of Beijing in the early morning. Finally, they met in front of Xinhua Gate in Zhongnanhai. No greetings, no communication. What they are thinking about is how to report the disaster to the central authorities as quickly as possible.

  4 hours and 18 minutes after the earthquake. Beijing, Ziguangge, Zhongnanhai. Li Yulin reported the disaster of Kailuan Coal Mine to the central leadership: there are still thousands of miners underground.

  Li Yulin people didn’t know at that time that thousands of miners who fled to the alleys were waiting for an order in the dark 590 meters underground in Kailuan Coal Mine. After 40 years, Zhang Guocheng, an electromechanical worker, still clearly remembered the scene at that time.

  Zhang Guocheng recalled: "At that time, it gave me the feeling that the working face collapsed, and the boards fell off, so we forced our way out through a small seam. The workers who came down from the construction site waited for the instructions from the leaders, and Xi’ an did not move. At that time, the organization was particularly strong and there was no chaos. "

  The underground search was carried out nervously and orderly until the last worker was found. This team of thousands of people began to move step by step to the wellhead that did not collapse with the miner’s lamp overhead. In the end, all miners were safely raised.

  Tangshan airport. Li Shengtang waited in the dispatching room all night, constantly debugging the buttons of the radio station for fear of missing any signal in the air.

  9 am, the fifth hour after the earthquake. Finally, the radio came to call Tangshan Station in secret language, demanding landing conditions: this Mi -8 helicopter, which took off from Beijing Shahe Airport two hours ago, was the first rescue plane sent by the central authorities.

  As the relief materials arrived in Tangshan, Li Yulin, who reported the disaster to the central authorities and returned to provide relief. On the way back to Kailuan coal mine, he shouted at the top of his voice and told the affected people along the way that the central government had decided to help Tangshan.

  Li Yulin said: "I told them about the situation, and there were more and more people around. Oh, I’ve never heard that slogan. It’s all from the heart. Almost all of them shouted when they broke their throats. Many wounded people were lying on the ground. Although they couldn’t shout, I still remember the strength of opening my mouth now. "

  Only when Li Yulin returned to Tangshan did he know that 14 relatives, including his parents and son, were killed in the earthquake. After hastily burying the next of kin, Li Yulin returned to the mine. With more than 20,000 miners trapped in Tangshan, Kailuan Coal Mine officially resumed production on the 10th day after the earthquake. "After the injured people have settled the dead, they all come back to mine. There are annoying drainage and mine protection, restoration of construction on the well, cleaning up things, etc., all of which are spread out. After ten days, the basic mines are full of people. At that time, everyone has difficulties, and if there is no difficulty, they will all come. "

  As railways and highways have been severely damaged, opening air passages is the only choice for disaster relief. The air rescue officially began 5 hours and 18 minutes after the earthquake. However, the power was interrupted, the runway lights were completely extinguished, and there was no navigation equipment. Tangshan Airport became "blind". Without runway lights, the soldiers collected hundreds of lanterns instead. Thirteen types of aircraft from more than 30 airports across the country took off and landed in nearly a thousand aftershocks by listening to Li Shengtang’s ears and observing with the naked eye. When I was most nervous, I took off and landed a plane in an average of 2 minutes, which created a miracle in the history of world aviation. During the critical period of 14 days after the earthquake, more than 20,000 wounded people and countless relief materials took off and landed from the narrow runway of Tangshan Airport.

  Li Shengtang said: "It is quite difficult to take off and land. Some large routes and small routes take off head-to-head, cross-take-off, and take off at both ends, and use one runway as two runways to maximize the airport take-off and landing rate, transport more wounded people and transport more relief materials. Up to 360 a day, with an average of 200 take-off and landing every day. I haven’t washed my face or rested for fifteen days. "

  On August 11th, 15th day after the earthquake, the land route from Tangshan to the outside world was finally opened. Tangshan in ruins is finally no longer an island.

  Li Shengtang, who is 80 years old, has some difficulty with his left foot. Every time he climbs a floor, he has to rest for a while. But as long as he hears a plane flying overhead, he will still be excited.

  In the subsidence area of Kailuan coal mine where the victims were buried, now, the 2016 Tangshan World Horticultural Exposition Park has been built. The miners who experienced the earthquake have already retired, and Zhang Guocheng, an electromechanical worker, took a liking to photography after retirement. He said that he loves to pat the new Tangshan more. "I took a lot of pictures when the World Expo was not engaged in gardening. Now I have taken a lot of pictures when it is completed. I don’t need to say that others can see the changes before and after, right?"

  However, when he reached the center of the park, he put down his camera and stood quietly. The theme sculpture "Danfeng Chaoyang" in front of him, which symbolizes the nirvana of the phoenix, seems to remind everyone who comes here not to forget the city’s past.

  Zhang Guocheng said: "I have been in Tangshan for more than 60 years. You see that so many people died in the earthquake at that time and buried their bodies to restore their homes. More than 200,000 people died in Tangshan. He can still stand tall and stand tall. It is time to resume production and resume production. How to live and live? This is Tangshan people!"

Precautionary measures for tornado weather

1. At home, be sure to stay away from doors, windows and the outer walls of houses, and hide in the wall or small room opposite to the tornado. The safest place to avoid a tornado is the basement or semi-basement.

2. In case of pole falling and house collapse, cut off the power supply in time to prevent electric shock or fire.

3. When there is a tornado outside the field, you should look for low-lying ground nearby, but stay away from trees and poles to avoid being smashed, crushed and electrocuted.

4. When the car encounters a tornado when going out, never drive to avoid it, nor do you avoid it in the car, because the car has almost no defense ability against tornadoes, so you should leave the car immediately and avoid it in low-lying areas.

New mothers are the most lonely, and nearly 90% have lost their social life.

   


  The new mother left most of her time to her children.


  Having children is something to be happy about. But a recent survey in Britain found that women who are first-time mothers feel most lonely in the first year after their children are born. The main reason is that they have no time and energy to contact relatives and friends during childbirth and maternity leave, thus being out of touch with the outside world.


  Nearly 90% lost social life.


  The British "Mom and Baby" magazine and Tesco Supermarket Co., Ltd. jointly conducted a survey on about 2,000 new mothers with an average age of 29. It turns out that many of them need to work hard to adapt to the new identity of "mother".


  About two-thirds of new mothers said that they lived far away from their mothers and had little contact with them. In addition, they basically lost contact with other relatives, friends and colleagues. More than half of new mothers feel "lonely and isolated". Among the women surveyed, on average, each person has only 90 minutes a day to get in touch with people except their husbands and children, and the rest is given to the children.


  Many new mothers say that after the birth of their children, most of the quarrels between them and their partners are due to this-they are "lonely and isolated", but their partners work or engage in social activities as usual.


  Caused by modern lifestyle


  The survey results said: "Less than 30% of new mothers’ mothers can help look after their children, while one third of new mothers’ mothers-in-law never help look after them."


  British media reported that the lifestyle of modern society is that people live farther and farther away from their relatives and friends, which makes motherhood more challenging.


  "Being away from work, giving birth to children has an arduous physical and psychological adaptation process for women. This is a brand-new life, which is completely different from what they used to live." Dalrymple, editor of Mommy and Baby magazine, said.

Louis Koo’s "Searching for Qin" is expected to start in March. Jessica Hester Hsuan: Still changing the script

1905 movie network news According to Hong Kong media reports, actress Jessica Hester Hsuan said at an event on February 20th that the film version of "Searching for Qin" is expected to be officially launched at the end of March this year, but she revealed that she has not seen the final script yet.


"Because there is no script yet, I have been changing it, and I want to make it better. When I was having dinner with my friends, the other party put forward some opinions. I think I would tell Gu Zi (Louis Koo) if I could." When asked whether the movie version continued the story of the TV series, Jessica Hester Hsuan immediately responded: "The old boss won’t let me talk!"


As early as 2015, it was reported that Louis Koo prepared and negotiated for the copyright of the novel "Searching for Qin" and prepared to shoot a film version. He also intended to invite Du Qifeng to be the director, but he was not satisfied with the script and never put it into shooting.In 2016, the news came out again that the film would start shooting in Inner Mongolia in 2017, and LAM Raymond, Jessica Hester Hsuan and other original people all returned, but in early 2017, Louis KooDeny the news,It means that the project is still in the stage of script creation.


In March 2017, Huace Film Company obtained the novel copyright of Searching for Qin, officially announced that it would jointly produce the film version of Searching for Qin with Tianxia One Film Company founded by Louis Koo, and exposed two concept posters at the same time, and then announced that the film would be directed by the new director Li Zhenlong, and there was no news about the filming. Four years later, can the film version of Qin Xun Ji really start shooting as scheduled? Triggered speculation.


The TV series "Searching for Qin" is adapted from Huang Yi’s martial arts novel of the same name. It is a drama celebrating the 34th anniversary of TVB34 in 2001, starring Louis Koo, LAM Raymond, Jessica Hester Hsuan, Sonija Kwok and Jiang Hua. The drama mainly tells the story of Xiang Shaolong, an elite G4 in the 21st century, who traveled through time and space to return to the Warring States period more than 2,000 years ago to find Qin Shihuang.Being "the originator of crossing the drama" is a classic screen memory of many viewers.Louis Koo also won the My Favorite Actor Award for the second time with the role of Xiang Shaolong.

"Searching for Qin" is Louis Koo’s last work in TVB. Since he entered the film circle in 2001, he has never appeared in TV series.

Looking at power consumption through inductance loss, the calculation is not complicated at all.

Address quoted in this article: https://www.eepw.com.cn/article/201706/346888.htm.

one, overview

The power consumption of power supply is various, including switching loss, input/output capacitance loss, static power consumption of controller and. This paper mainly introduces the simple calculation. Including two aspects: one is the loss related to the magnetic core, that is, the traditional iron loss; The second is the loss associated with the inductor winding, which is commonly called copper loss.

Total Power Dissipation(W)= CopperLoss + CoreLoss

CopperLoss = IRMS2*RDC(mΩ )/1000

CoreLossGenerally, it is obtained by checking the manufacturer’s form.

Photos of switching power supply on a motherboard

2, calculation method

Take Pulse’s PA1513NL series inductor as an example, and adopt PA1513NL.321NLT. The datasheet downloaded from official website is as follows. The basic parameters are: the inductance is 320nH, and the DC resistance is 0.53 11.3%.

In the design, we use this resistor in the switching frequency of 600kHz and the load current I.LOADIn the BUCK circuit of 30A, where iripple = 30% * i.LOAD.

According to the above formula, it can be easily calculated that the maximum copper loss is:

CopperLoss = IRMS2* RDC(mΩ )/1000 =(30A)2 *(0.53*111.3% mΩ )/1000 = 0.531W

Regarding the maximum iron loss, we must first calculate △B: (because the inductance error is a curve, we use the normal value to calculate it).

△B = .23* L(nH)* △I = 0.23 * 320(nH)* 30% * ILOAD = 662.4

Since the switching power supply works at a frequency below 600KHz, the iron loss can be found to be about 0.18W by looking up the table.

Then the total loss is as follows:

Total Power Dissipation(W)= CopperLoss + CoreLoss = 0.711W

By looking up the table, we can get that the temperature rise of the inductor is about 45 degrees Celsius under normal working conditions.

The main functions of evaluating the loss of inductance are: first, to see whether the loss of inductance will cause the overheating of inductance, which will lead to the decrease or even damage of inductance value; The second function is to adjust the parameters of inductance and improve the efficiency of the whole power conversion system.

threeAbout CoreLoss

In fact, the calculation method and curve of CoreLoss are not given on the datasheet of many inductance companies. If so, it is almost impossible to calculate the iron loss. In this case, there are two suggestions.

If this inductor is used in high-current and critical equipment, then please choose a supplier that provides iron loss, such as Pulse, Wurth, JW Miller, etc.

If the current is relatively small or the switching frequency is relatively low, the general iron loss is not the key factor. Then first evaluate whether the copper loss is OK, and leave a certain margin. If the inductance is overheated in the subsequent test, try to reduce the switching frequency of the power supply, or adopt an inductance with a smaller DCR.

Language is the key to the future.

  As a symbol of the country and the nation, language is not only the hard power of the country’s development, but also the strong soft power of the country. The level of national language ability affects the overall strength of the country.

  On the 14th, the 18th National Publicity Week for Promoting Putonghua was officially launched. This year’s theme is "Promoting Putonghua according to law and enhancing the country’s soft power". Its purpose is not only to mobilize resources from all aspects of society to actively participate in the popularization of the national common language, but also to apply them to many fields such as economy, society and culture. This activity also makes people further understand the importance of language and think about language problems.

  "The reason why people are human is that they speak." Language is the basic tool for human beings to express their thoughts, acquire knowledge and communicate, and plays an important role as a bridge and link in our lives.

  Language is the key to a country. When meeting with German sinologists, Confucius Institute teachers’ representatives and students’ representatives in Berlin in March 2014, the Chairman of the Supreme Leader pointed out that "the important tool of communication is language. The charm of a country’s culture and the cohesion of a nation are mainly expressed and transmitted through language. Mastering a language means mastering the key to a country’s culture. " Under the background of world multipolarization, economic globalization, cultural diversity and democratization of international relations, people-to-people communication plays an important role in cooperation between countries. Mastering different languages is conducive to effective communication, which enables people from different cultures, races and countries to know and understand each other in the process of feeling the profound connotation of different civilizations, thus narrowing the distance between people and countries and promoting the mutual tolerance and harmonious coexistence of world civilizations. Especially in the context of the current construction of the Belt and Road, it is as important as the interconnection of material civilization to promote the cultural exchange of countries along the Belt and Road with the exchange of languages, and then promote the "communication between the people".

  Language is the key to wisdom. With the advent of internet plus, Industry 4.0 and new hardware era, science and technology such as big data, cloud computing, Internet of Things and mobile terminals have developed rapidly, and the intelligence of families, cities and society is getting higher and higher. In the past, many things that had to be done by hands can be easily done with a password or a button in the intelligent society. For example, to dial someone, just say the name of the other person and you can dial the phone; To buy a train ticket, just say the name of the place of origin accurately, and the self-service ticket vending machine will issue the ticket immediately; Turn off the electrical equipment at home, as long as you say the relevant password or verification code, the power will be cut off immediately … In the intelligent society, only universal, standard and standardized languages are effective, and the standardized construction and popularization of standardized languages are particularly important in our lives. It can be said that in the virtual space of the Internet, the effective expression of language plays a key role in the healthy operation of our smart home, smart city and smart society.

  Language is the key to the future. In the future international competition, the language problem has risen from the general problem to the national level, and language has become a strategic weapon to safeguard national interests and security. As a productive force, language ability has also played a great role in promoting the development of language industry. Statistics show that there are about 1.2 million employees in China’s language industry, and the annual output value of translation and localization business is about 12 billion yuan. Facts show that the language industry has become a new growth point in the future economic development. Fully tapping and rationally utilizing the cultural and economic values of language resources, vigorously developing language resources and supporting the development of language industry will certainly provide new impetus for economic development while providing diversified language services for the society.

  As a symbol of the country and the nation, language is not only the hard power of national development, but also the strong soft power of the country. The level of national language ability affects the overall strength of the country. The healthy development of language affects the future political, economic and cultural development of the country, and only by winning the future of language can we win the future of the country. We should re-recognize the function and function of language, and the whole society should pay more attention to language and development issues, vigorously strengthen the national and national language capacity building, build a language power, and enhance the soft power of the country. (Yao Xishuang, Director of the Language Application Management Department of the Ministry of Education)

Global epidemic: Chinese communities in new york actively support the local anti-epidemic front.

  On April 6, local time, a woman wearing a mask walked on the street in the Chinese community in Flushing, new york. According to statistics released by Johns Hopkins University in the United States, as of the evening of 6th, there were more than 360,000 confirmed cases in COVID-19 in the United States, including more than 130,000 confirmed cases in New York State. China News Service reporter Liao Panshe

  China news agency, new york, April 9 th: Global epidemic: Chinese communities in new york actively support the local anti-epidemic front line.

  China News Service reporter madelin

  On the afternoon of April 9th, it rained heavily in new york. At the new york Asian Association in Brooklyn, several volunteers are loading boxes of epidemic prevention materials into the car in the rain, ready to send them to a local police station.

  Wang Yibing, president of new york Taishan Overseas Chinese Women’s Federation, helped count and carry materials at the scene. She said that the donations of the Asian General Association are all front-line units, including hospitals and police stations, which are essential for fighting the COVID-19 epidemic. "My idea is to make a contribution." Wang Yibing said, "There are no eggs under the nest, right?"

  Chen Shanzhuang, chairman of the Asian General Assembly, said that the Asian General Assembly has raised 30,000 medical masks, 30,000 gloves, 1,200 hand sanitizers, 1,500 protective clothing and other materials, which will be sent to the Langone Medical Center of New York University in batches in the near future, the Brooklyn Southern District General Administration of the New York Police Department, and subway, fire fighting, postal and other units.

  As of the evening of the 9th, more than 160,000 cases of Covid-19 infection were confirmed in New York State, and more than 7,000 cases died. The number of confirmed infections in New York State has exceeded that of any other country outside the United States.

  "More than two months ago, we raised more than one thousand boxes of masks for Wuhan. Now the epidemic situation in new york is serious, and the Asian community is very concerned about this. " Chen Shanzhuang said that the Asian General Assembly itself aims at serving the community, and now it is only natural to do what it can to fight the epidemic. He mentioned that epidemic prevention materials are scarce at present, and this batch of materials was not raised until last week. "I hope that those who have the ability will continue to donate, and we will deliver the materials to the frontline units in time."

  "Since the outbreak of the epidemic in new york, the Chinese community has actively donated to hospitals, police stations, sanitation and other departments." Gu Yaming, a member of new york City Council, said that doctors, policemen and other groups risked their lives to fight the epidemic, and the community was very grateful for their work.

  "There are also many Chinese friends who have called me and asked me what (they) can do to fight the epidemic." Gu Yaming told reporters, "One of them made 50 fried rice and sent it to the hospital." He believes that the support of the Chinese community is spontaneous, and these little things also represent their love.

  In the past two weeks, the Peking University Greater new york Alumni Association has raised more than 56,000 US dollars in donations, 9,000 masks and 819 sets of infectious disease protection equipment to support 18 hospitals. On the support list, Amherst Hospital, Queens Presbyterian Hospital and Mount Sinai Hospital are all hospitals with the heaviest task of treating patients in COVID-19.

  Yu Ge, the president of the Alumni Association, lives in Long Island, new york. "It can be said that every Chinese community around me is in action." She told reporters that after the alumni association initiated fund-raising, people continued to take the initiative to join, and some of them even "have multiple jobs" and participated in fund-raising and material delivery in several societies.

  While the Chinese community actively supports new york in fighting the epidemic, hate crimes under the pretext of Covid-19 are also increasing, and news that Asian groups, including Chinese, are insulted or even hurt is frequently reported in newspapers. In this regard, Gu Yaming pointed out that it is completely wrong and very dangerous to incite racial sentiment in the name of the epidemic. "Covid-19 has nothing to do with race, and anyone who is not well protected may be infected." Gu Yaming said that this should never be used as an excuse to target Chinese or Asians.

  Gu Yaming said that he had communicated with the Mayor of new york and the Governor of New York, asking them to send more police to protect the Asian community. He reminded that Chinese people should call the police immediately if they encounter hate crimes, and his office can also provide necessary help to the victims.

  "The current epidemic is a disaster." Gu Yaming said that he hoped that Chinese people would protect themselves while supporting the "anti-epidemic". "Please don’t have dinner parties, go out for protection and keep a social distance from others." He said that if everyone can do this, I believe that Covid-19, an "invisible enemy", can be defeated step by step.

Dengue fever is in the high season, so be careful when these symptoms appear recently →

  As the temperature rises,

  Mosquitoes gradually entered the peak of activity.

  After the increase of mosquitoes

  A disease called dengue fever.

  Also began to quietly approaching …

  What is dengue fever?

  Dengue fever is an acute infectious disease caused by dengue virus, which is spread by the bite of Aedes mosquitoes. After a mosquito sucks the blood of an infected person, it usually takes about 8 to 10 days to replicate the virus in the body, and then it can spread the virus when it bites the next time, that is, the transmission route is "patient → Aedes → others". Dengue fever is generally not transmitted from person to person.

  People in China are generally susceptible. After infection, the incubation period is generally 1 ~ 14 days, but some people do not get sick (called recessive infection). Patients and recessive infected people are the main sources of infection.

  Symptoms of dengue fever include sudden fever, headache, orbital pain, muscle and joint pain (commonly known as "three pains and one fever"), and rash. In severe cases, it may develop into dengue hemorrhagic fever or dengue shock syndrome, which is life-threatening.

Dengue fever is in the high season, so be careful when these symptoms appear recently →

  Source: Network

  Where is dengue fever mainly prevalent?

  Dengue fever epidemic areas are mainly concentrated in tropical and subtropical areas, Southeast Asia, the Western Pacific and America, including Thailand, Indonesia, Malaysia, the Philippines and other countries around China. Dengue fever epidemic in these areas exists all the year round, and the number of cases is large.

  The epidemic situation of dengue fever in China is mainly imported from abroad, and there are also local cases caused by imported cases. The main overseas sources are Southeast Asian and South Asian countries such as Myanmar, Cambodia, Indonesia, Thailand, Laos and Malaysia. Local cases are mostly distributed in coastal or border areas such as Guangdong and Yunnan.

  Please pay attention to cross-border travel!

  With the arrival of summer vacation, the number of cross-border and inter-provincial personnel has increased, and the risk of epidemic input has increased. If you have stayed in Southeast Asia, South Asia, Latin America and other dengue endemic areas within 2 weeks before the onset of the disease, or there are confirmed cases of dengue fever around you, and you have symptoms such as fever, rash, headache and myalgia, you need to consider the possibility of getting dengue fever, go to the hospital as soon as possible, and take the initiative to explain your travel history so as to get treatment as soon as possible. At present, there is no specific antiviral drug for dengue fever.

  The mortality rate of typical dengue fever is less than 1%, but if it is not treated in time, it will become severe and the mortality rate will exceed 20%. Therefore, early identification, early diagnosis and early treatment are important measures to prevent serious illness and further spread.

  How to prevent dengue fever?

  According to the characteristics of replication and transmission of dengue virus in mosquitoes, the key to prevent dengue fever is to reduce mosquito bites, which includes physical anti-mosquito measures such as mosquito nets and screens, as well as chemical anti-mosquito methods such as spraying pesticides and using mosquito repellent.

  In addition, cleaning up indoor and outdoor stagnant water and reducing mosquito breeding environment are also important measures to prevent dengue fever.
