  Xinhua News Agency, Lhasa, November 18 (Reporter Liu Hongming, Bai Shaobo) The reporter learned from the Seismological Bureau of Xizang Autonomous Region that at 06: 34 on November 18, an earthquake with a magnitude of 6.9 occurred in Milin County, Linzhi City, with a focal depth of 10 kilometers. Seven counties (districts) in the city have obvious earthquakes, and no casualties have been reported yet. Some roofs in Lulang Town, Bayi District fell off, houses were shattered, and some villages were blacked out.

  After preliminary understanding, the earthquake in Milin County and the area near the epicenter was strong. The roof of Lulang Town in Bayi District fell off, the houses in Zhaxigang Village and Luobu Village were shattered, and all the villages in Layue were blacked out. There were no reports of casualties.

  Basang Tsering, secretary of the Party branch of Zhaxigang Village, Lulang Town, said that when the earthquake occurred, the house shook so badly that it was unstable to stand in the house. It was the first time for him to experience such a strong earthquake. At present, there are cracks in five or six houses.

  The reporter learned from State Grid Xizang Electric Power Co., Ltd. that as of 8: 00 on the 18th, Xizang Power Grid and Linzhi Power Grid were operating normally, and the company had started the earthquake emergency response mechanism.

Xizang Autonomous Region Seismological Bureau, China Seismological Bureau and China Seismological Network Center are having a video conference on the earthquake situation and disaster situation in the earthquake area, and the earthquake emergency field team is rushing to the earthquake-stricken area.

  At present, local investigations and statistics are being carried out in an orderly manner. Xinhua News Agency reporters are rushing to the earthquake zone, and the earthquake damage is being investigated and verified.

Observation | US "Tianjun" clarifies the vision of the next generation space architecture and seeks to maintain its absolute advantage.

Recently, SDA released the first information consultation on the federal business opportunity network of the US government, seeking the design concepts and schemes of satellite platforms, payloads, launch platforms and related ground facilities needed for the development of the next generation space architecture from the industry.

This is the first information consultation book issued by NASA since its establishment on March 12, and its development trend deserves attention.

The U.S. military believes that active satellites are powerful, but their survivability is insufficient, so it is necessary to explore new platforms. The picture shows the American SBIRS missile early warning satellite.

The development thinking of American space equipment is brewing a major change.

After Trump took office, he attached great importance to space. From the reconstruction of the space command, the establishment of the space army to the establishment of the space development agency, the US military’s space decrees, military orders and space equipment research and development system are undergoing major adjustments and changes. In this context, the US military is speeding up the planning and design of the next generation space system. The new version of the Missile Defense Assessment Report and the first project solicitation notice of the Space Development Agency reveal some clues.

In 1983, in order to prevent hostile countries from launching nuclear attacks on the United States and its allies, then US President Ronald Reagan proposed the "Star Wars" plan, which consisted of intercontinental ballistic missile defense and anti-satellite, and advanced the development of space weapons, which had a significant impact in history. Because the investment and technical difficulty of the "Star Wars" plan was too great, which exceeded the objective reality at that time, it was forced to suspend in 1993 and turned into a more realistic and feasible missile defense plan. In recent years, due to the rapid development of missile penetration technology, especially hypersonic technology, the missile defense system in the United States, which is mainly based on land and sea, is facing development bottlenecks, and there are calls and trends to shift the focus of missile defense to space.

On January 17 this year, the new version of the US Missile Defense Assessment Report clearly stated that the use of space can provide a more effective, flexible and adaptable missile defense posture. Space-based sensor system is not limited by geography, and can monitor, detect and track missiles launched almost anywhere in the world; Space-based interceptor and directed energy weapon are effective ways to intercept missile booster phase, effectively resist penetration and greatly improve the overall efficiency of missile defense system. Confirmed by the above statement, the US Congress has asked the Ministry of National Defense to carry out special research and demonstration on space-based sensors, space-based interceptors and even particle beam weapons, and come up with concrete and feasible development plans.

India conducted an anti-satellite test in March this year.

On July 1, the US Army’s New Space Development Agency issued the first project solicitation notice, which clearly pointed out the military needs of the US military’s new generation of space system construction to missile defense and space confrontation, marking a major change in the development ideas and ways of the US military’s space equipment system. The background is that the strategic focus of the United States has shifted to the competition of big countries, and it is believed that the existing space architecture and equipment can not maintain absolute superiority, especially in the case of the continuous development of anti-satellite missiles, cyber attacks and common-orbit spacecraft in some countries, once the space system dominated by large spacecraft is destroyed, it is difficult to replenish it in a short time, that is, there is insufficient flexibility; The second is that the existing space architecture and equipment can’t cope with emerging threats, especially hypersonic weapons, and the active missile early warning satellites can’t effectively provide timely early warning and tracking.

The new architecture will have a subversive impact on space attack and defense.

The first project solicitation notice of the Space Development Agency borrowed the idea of DARPA "Black Jack" satellite project, turned to the booming commercial space technology to seek subversion, and tried to develop the concepts, methods, technologies and systems related to the next generation flexible, flexible and agile space system based on micro-satellite technology, rapid launch technology and artificial intelligence technology.

According to the eight key space capabilities proposed in the "Space Vision of the Ministry of National Defense", the Space Development Agency proposed that the next generation space system of the US military should be composed of seven functional layers. First, the transport layer: it provides 7×24 hours uninterrupted and low-delay data transmission and communication around the world; The second is the tracking layer: it provides space-based target detection, early warning, tracking and indication to defend against the threat of advanced missiles (including hypersonic weapons); Third, the monitoring layer: monitoring time-sensitive targets around the clock, providing key guarantee for attacking enemy missile launchers, radar stations and command nodes before launching; The fourth is the deterrent layer: it provides the target situation awareness and rapid access and maneuver in the space range of the earth and the moon, and responds to the challenges posed by space attack and defense; Fifth, the navigation layer: provide positioning, navigation and timing capabilities in the environment of GPS refusal, and enhance the joint operational support capability under the conditions of space confrontation; Sixth, battlefield management: provide battlefield management, command, control and communication based on distributed artificial intelligence, including on-board intelligent autonomous mission planning, data processing, encryption and distribution, etc., and directly provide space information support for tactical users; Seventh, the ground support layer: providing the carrier system and ground facilities for the rapid maneuvering launch measurement and control of large-scale small satellite constellations, deploying portable, serialized and intelligent satellite application terminals, and providing supporting ground system support for flexible, elastic and agile on-orbit systems, thus forming an economical and practical next-generation space system.

The next generation space architecture attaches great importance to dealing with emerging threats.

As can be seen from the above-mentioned seven-layer architecture, the tracking layer and the monitoring layer mainly serve missile defense operations, especially for the whole-course target detection, tracking and indication of hypersonic vehicles; The deterrent layer and navigation layer are mainly oriented to space attack and defense confrontation, and the operational scope extends from low orbit and geostationary orbit to higher and farther earth-moon space; The battlefield management faces the intelligent development of space, further enhancing the timeliness and convenience of space-based information to support joint operations; The ground support layer provides rapid launch, measurement and control and application support for large-scale small satellite constellations, ensuring the rapid supplement and update of small satellite constellations under the condition of confrontation, and improving the efficiency of large-scale ground application of satellites; The transport layer provides interconnection between heaven and earth, between satellites in different functional layers and between satellites in the same functional layer, which constitutes the technical foundation and common support of the next generation space system.

To sum up, the development concept of the next generation space system of the U.S. military has changed from "making great beauty and ensuring zero risk" in traditional military space to pursuing "scale, economy and not being afraid of hitting" to win advantages, focusing more on missile defense and space attack and defense in target positioning, and emphasizing more practical and integrated functions and flexibility, flexibility and agility. Once the next generation space system of the US military is realized and put into actual combat, it will have a subversive impact on missile defense and space attack and defense operations, and change people’s existing understanding of the space battlefield, which deserves close attention from the world.

Memories of the Long March Departure 300,000 people keep a big secret.

  Yudu is a county, located in southern Jiangxi; Gongjiang River (called Yuduhe in the capital) flows through the city.

  On a rainy day in April this year, for the first time, I saw people from all walks of life offering flowers in front of the monument of the starting point of the Long March of the Central Red Army in the rain. Although the ground in front of the monument was still being renovated, I was still very moved.

  Standing on the banks of the Duhe River, life and death, gathering and scattering, historical scenes are coming. I seem to hear the clanging footsteps of Red Army soldiers from far and near … … At that time, perhaps no one thought that crossing this river would be a long road of 25 thousand Li; Perhaps no one thought that along the way, we will face so many difficulties and obstacles and so many where will you go!

  In order to carry forward the spirit of the Long March and remember the great achievements of our ancestors, in 2009, Yudu County Party Committee and county government invested nearly 10 million yuan to rebuild and expand the Memorial Park of the First Crossing of the Central Red Army’s Long March, and built the Memorial Park of the Starting Point of the Central Red Army’s Long March.

  In August, the reporter came to Yudu again and remembered the touching deeds of countless revolutionary ancestors in the memorial park of the starting point of the Long March of the Central Red Army.

  Yuduhe will never forget it

  In late September, 1934, Chiang Kai-shek held a meeting in Lushan Mountain to deploy the "Iron Drum Plan", and set Ruijin as the ultimate goal, forming an encirclement with Ruijin as the center and a radius of 150 kilometers, thus annihilating the Central Red Army in one fell swoop.

  Chiang Kai-shek laid down his wishful thinking, but his military plan was leaked to his subordinate Xiang Yunian, who was an underground member of the Chinese Communist Party.

  Xiang Yunian wrote the information in the student dictionary with special potions overnight and rushed to Ruijin. However, along the way near Hongdu, there are already checkpoints, barbed wire and bunkers of the Kuomintang. In desperation, Xiang Yunian smashed his four teeth with stones, dressed unkempt and ragged, and hid the information in a filthy rice bag, and finally got through the heavy blockade of the Kuomintang. On October 7, Xiang Yunian, dressed as a beggar, arrived at Ruijin Shazhouba, and this top secret information that changed the fate of the Red Army was handed over to the CPC Central Committee.

  On the evening of October 17th to 20th, 1934, more than 86,000 people from the Central Soviet Area, the organs of the Central Military Commission, their directly affiliated troops and the 1st, 3rd, 5th, 8th and 9th Army Corps crossed the Taidu River from the Shanfengba in Zishan Township of Yudu, the east, south and west gates of the county, and the Mengkou, Carp, Shiwei and Yuwengbu in Luo ‘ao, respectively, and embarked on a long journey.

  According to Zhang Xiaoping, deputy director of the Memorial Hall for the Long March of the Central Red Army, there was no bridge on the Yudu River at that time, but the widest part of the river was 600 meters, the water depth was 1 to 3 meters, and the flow rate was very fast, which became the first natural barrier for the Red Army to cross the Long March. Only three ferries were suitable for wading across the river. In order to ensure the safety of large troops and cross the river quickly, the Red Army decided to temporarily recruit civilian boats as piers, then lay boards on them and build pontoons at five ferries.

  A fisherman came up with a good way to hang a lantern on the bow of each civilian boat, which can be arranged in a row at night, greatly improving the efficiency of crossing the river. Many old people still remember the details of crossing the river.

  By the time the Long March started, the Kuomintang troops were approaching the capital. In the air, I flew over the Kuomintang plane from time to time. In order to avoid enemy reconnaissance, the soldiers and civilians built bridges every afternoon and demolished them in the early morning of the next day, leaving no trace. The pontoons of the five ferries were repeatedly dismantled and built 15 times.

  During the process of bridging, I heard that the Red Army was short of wood, and many people along the coast took down their beds, door panels and melon sheds without hesitation and sent them to the bridge site. "There is a grandfather named Zeng who even donated the coffin that has been old for a hundred years." Whenever talking about this history, Zhang Xiaoping always can’t restrain his inner excitement. "Yudu County at that time was really ‘ Don’t close the door at night ’ Ah! "

  Uncle Zeng’s story has been handed down, but Uncle Zeng and his descendants have no way to find it.

  "Send the Red Army along the Yudu River, and remember the soldiers and civilians." At that time, the people of Yudu gave everything they had, and they dispatched tens of thousands of laborers and more than 800 ships.

  At the Memorial Hall of the Central Red Army’s Long March Departure in Yudu County, the reporter saw the door panels for the pontoon bridge, as well as sheets, straw sandals, laundry baskets, rattan baskets, pots and bowls, and fishing boats … … These relics used by countless heroes in the heyday are all full of touching revolutionary stories, one by one with touching red memories. Approaching these cultural relics is like walking into that period of history and past events … …

  300,000 people keep a big secret.

  Yudu River is crowded with people. Tens of thousands of men, women and children stood at various ferries to see the Red Army off. Yang Dezhi, then head of the first regiment of the First Division of the Red Army Corps, later recalled: "In the middle of the night, the autumn wind blows the branches and leaves, blows the Yudu River, which is a thousand miles away, and blows the officers and men dressed in light clothes. The cold is very heavy. When we look back at the people holding lanterns and torches on the other side to see the Red Army off, we can’t help but feel warm. " Among the people who rushed to the Yudu River to see the Red Army off, except for childish and ignorant children running around, the faces of adults were all sad, and some were still crying secretly. The cousins took the hands of the Red Army soldiers and repeated a very simple sentence: "I look forward to your early return, I look forward to your early return!"

  At No.1 North Gate of Lianxi Road, DuDu County, stands an old building — — Former residence of Comrade Mao Zedong on the eve of the Long March. The comrades of the Propaganda Department of Yudu County Committee told me that Mao Zedong lived here when he assembled before leaving Yudu. Only a few photos were actually displayed in the old residence, but from these precious photos, the password of "Long March from Yudu" can still be interpreted.

  Since October 7th, 1934, the Central Military Commission (the Central Military Commission (CMC), chinese soviet republic) has issued orders to the 1st, 3rd, 5th, 8th and 9th Army Corps, the main force of the Central Red Army, to hand over their defense one after another, evacuate the battlefield in secret and concealment, and assemble in Yudu together with the first field column (also known as the Red Star column) and the second field column (also known as the Red Chapter column) of the Central Committee.

  In mid-October, the Central Military Commission issued an order to organize the central party, government and military organs into the first and second field columns of the central government. On the evening of the 10th, the first field column started from Ruijin Meikeng, Tian Xin Wei, Jiubao and Shimen Wei in Huichang, respectively, and moved into Yudu. The second field column set out from Ruijin Jiubao and Yunshishan and marched into Yudu. On the 13th, the two columns arrived at Lingbei, Hexi Port and Gutian in Yudu successively to gather and rest.

  More than 80,000 Red Army main forces assembled and rested for 10 days inside and outside a county town, and then crossed the "first crossing of the Long March" safely and smoothly. 300,000 Yudu people imposed martial law in red, tightly blocked news, and created false appearances to confuse the enemy, making Kuomintang spies "deaf" and "blind" with nothing. The Kuomintang spy department knew nothing about this, and Chiang Kai-shek didn’t even get any news, so it was not until a month later that he discovered that the Red Army had moved.

  Eighty-two years ago, 300,000 people in Yudu shared a great secret, which was praised as a miracle by today’s party history researchers. Today, with the development of information, it is hard to imagine that 300,000 people can keep a common secret.

  Xiang Ying, Chen Yi, Chen Tanqiu, He Chang, Qu Qiubai and others were ordered to form the Central Sub-bureau of the Soviet Area after the Red Army crossed the Taiduhe River and left the Central Soviet Area in October 1934. In late February 1935, the Central Soviet Area was completely lost. Faced with the heavy encirclement of powerful enemies, the remaining Red Army was broken into parts and divided into nine roads to break through and transfer from the Hefeng area in Yudu. On the way, he was chased and killed by Kuomintang troops and vigilantes. Qu Qiubai, He Shuheng, He Chang, Li Cailian, Mao Zetan, Cooper, Liu Bojian, Liang Baitai, Zhou Yili, Yang Ying, Li Tianzhu … … A large number of senior party cadres died heroically in the breakout, and some of them were unaccounted for … …

  After the Red Army left, the people in Yudu risked their lives to help resettle more than 6,000 Red Army patients who stayed in Yudu, thus relieving the worries of the soldiers in front.

  In that era of blood shed, the Red Army, the people in the Soviet area and the people in Yudu were integrated, which could be said to be a piece of steel plate!

  The story of the boat paddle and the generator

  The items exhibited in the Memorial Hall of the Central Red Army’s Long March Departure have inspiring and tearful stories behind them.

  Here is a pair of well-preserved embroidered straw sandals, which were compiled by Xie Zhijian’s fiancee of the Red Army for him. Xie Zhijian was unwilling to wear them. After the victory, he returned home with straw sandals only to find that his fiancee had been killed that year.

  Here is a big iron pot with a bullet hole, which was the marching pot of the Red Army during the Long March and experienced bullets.

  On October 17, 1934, Li Shengren also joined the ranks of supporting the Red Army. "At that time, he (Li Shengren) was fishing at the Duhe Liyutan Ferry. At this time, several Red Army officers and men shouted on the shore and asked him to support the boat to the shore. It turned out that there were big troops crossing the river that night and wanted to ask the fishermen for help. " Li Mingrong said, "My father agreed without saying anything, and immediately mobilized other ship owners to help."

  Soon, Li Shengren called more than 20 fishing boats to meet. The big boat takes 10 people at a time and the small boat takes 5 people, crossing the 600-meter-wide Yudu River again and again. In the vast darkness, bamboo poles and boats rowed out of the water and sent hundreds of Red Army troops to the Long March Road. On the evening of October 18th, at another ferry, it was another night, and Li Shengren and others repeated the action of the previous night.

  At parting, the Red Army left 20 pieces of ocean and some rice to the fleet that helped them, and thanked them: "Thank you! We will come back again and will not forget your fishermen brothers! "

  Two days later, all the main forces of the Red Army left Yudu, and Li Shengren also left. In order to avoid the revenge of the Kuomintang, their family drifted away for 15 years and didn’t return to their hometown until the founding of New China.

  Nowadays, the boat paddles and lanterns used by Li Shengren are placed in the memorial hall for the departure of the Long March of the Central Red Army, and together with the cultural relics spontaneously donated by the local people, they listen to the sound of water not far from the Duhe River.

  The memorial hall also records the story of an old Red Army, Xie Baojin, who once carried a 68kg generator, followed the team through the Long March and sent this important machine to Yan ‘an.

  Xie Lingui, the nephew of Xie Baojin, told reporters that his uncle is big and strong. After joining the Red Army, he was selected to work in the Technical Unit of the Information Department of the Central Military Commission. His main task was to manage the generators used by the Central Military Commission to send telegrams with his comrades.

  On the eve of the Red Army’s transfer, a leader said to Xie Baojin, "These equipments belong to the Central Military Commission ‘ Ear ’ And ‘ Eyes ’ You have to make sure that nothing is lost. " Xie Baojin remembered this sentence, protected the generator as his own life, climbed the snow-capped mountains and crossed the snow, and carried it back to Yan’ an after thousands of difficulties and dangers, completing the task.

  After the victory of the war, Xie Baojin returned to Yudu to engage in scrap purchase. In 1976, Xie Lingui took his uncle Xie Baojin to see a doctor in Beijing. When he visited the museum, he saw a machine. At that time, his 78-year-old uncle was shaking all over, squatting down and touching the machine constantly, with tears in his eyes. "I thought my uncle was not feeling well. The commentator came over and said that this is a cultural relic and can’t be touched. My uncle cried excitedly and said," Little girl, do you know what this machine is for? I carried it all the way to Yan’ an. " When the commentator heard this, he immediately moved a chair to let his uncle sit down. "Uncle said that when he saw the generator, all the scenes of his comrades’ sacrifice came to his eyes, and he couldn’t help crying." He has always warned future generations to study hard. "Now all the children at home have graduated from college, and my uncle should be very pleased." Xie Lingui said.

  The people in Yudu are really nice.

  Farewell, Yuduhe! Farewell to the red land once defended with blood! General Yang Chengwu, then political commissar of the Fourth Regiment of the Second Division of the Red Army Corps, later wrote: "This is a scene that will never be forgotten."

  "Red flag hunting, horses neighing, neat team standing on the lawn across the river, a steady stream of people, gathered from all directions. They helped the old and brought the young to the Yudu River. Some villagers put boiled eggs into our hands, and some put handfuls of fried beans into our pockets. Some took our soldiers by the hand and asked, ‘ When will you be back? ’ Some can’t stop ‘ Whoops ’ Cry quietly. "

  "Men, women and children come to send each other, and tears are stained with clothes." The team set off, and the Red Army soldiers marched to the Yudu River in teams. "The sound of horses, burdens, bayonets, footsteps and songs are mixed with each other."

  By the Yudu River, men, women and children are holding sandals, food and money to say goodbye to their loved ones.

  Among the people who bid farewell, there was Ding Zhangfa. He and his mother came to the river from Gutian Village, Gongjiang Town, not far from Yudu River with five pairs of straw sandals and a big bag of dried sweet potatoes, trying to find their long-lost father in the Red Army. Team after team of the Red Army has passed, day after day, and I haven’t seen that long-lost figure. Finally, his mother gave straw sandals and dried sweet potatoes to five Red Army soldiers. Afterwards, Ding Zhangfa learned that his father had already died in rejuvenating the country before the Red Army’s Long March.

  Every time I explain this history, Xiao Tingting, the commentator of the Memorial Park, will mention some stories: In order to help the Red Army cross the river, the people along the coast took out the door panels and wood at home, and even some old people gave their life materials to the Red Army; In order to supply the Red Army with sufficient rations, four or five local people guarded an earth ridge (local equipment used to shell rice) and processed grain day and night, keeping "people stopping the ridge" … … At that time, Zhou Enlai once said emotionally: "The people in Yudu are really good, and the people in the Soviet area are really close."

  According to the statistics of researchers, from May to August 1934, just before the Red Army’s Long March, Yudu people donated 79,390 stones of grain. "At that time, this was equivalent to three years’ rations for 300,000 people in Duquan County." Zhang Xiaoping said.

  Before the Long March, Yudu people actively responded to the call of the CPC Central Committee to "expand the Red Army with a million tons of iron" and actively joined the army to participate in the war. More than 16,000 sons and daughters of Yudu participated in the Long March, which provided personnel support for the central authorities and the main force of the Central Red Army.

  According to statistics, during the Second Revolutionary Civil War, the number of people who joined the Red Army in Yudu reached 67,709, accounting for a quarter of the county’s total population at that time, including as many as 16,300 martyrs with names to test.

  The local Soviet government also organized nearly 10,000 migrant workers to go out with the army, which provided strong logistical support for the Long March. Most of them died on the way to the Long March.

  Saying goodbye, Yudu people believe that their loved ones will return. However, the cruelty of the war was beyond imagination. When Yudu children who crossed Yudu River were founded in People’s Republic of China (PRC), there were only 277 people left.

  The tall monument is facing the Changzhengyuan Primary School. On the weekend, the students of the school’s "Red Wa Band" were training. Dozens of people wore red military uniforms and octagonal hats and played "Ten Send to the Red Army" with full emotions. Sometimes high-pitched, intense, sometimes sad and sad tunes bring us back to the tragic scene of the Red Army’s Long March across the river 82 years ago.

  More and more people listen to music, and many people burst into tears.

Local meteorological departments tighten the "flood control safety string" to prevent heavy rain and secondary disasters.

  Frequent heavy rainfall in flood season will easily lead to mountain torrents, geological disasters and increased flood risk of small and medium-sized rivers. The local meteorological departments have earnestly put the people’s life safety in the first place, tightened the string of flood control safety, implemented their responsibilities, made every effort to do a good job in monitoring, forecasting and early warning of heavy rainfall and meteorological services for flood control and emergency rescue, kept a close eye on key parts, weak links and disaster-prone points, and made rolling judgments on the risks of secondary disasters to ensure a stable flood season.

  Liaoning: Start the rainstorm emergency response team to go to Panjin to carry out refined services.

  After the weather meeting on August 14, the party group of Liaoning Meteorological Bureau dispatched and deployed the meteorological service guarantee for flood control and disaster relief in the near future, requiring meteorological departments at all levels in the province to strengthen the bottom line thinking, strengthen the joint defense of river basins and tighten the "flood control string"; Strengthen the linkage between departments, strengthen the early warning of geological disaster risks, and keep the "lifeline"; Do a good job in flood drainage meteorological service and serve "autumn grain protection"

  Since the flood season, the precipitation in Liaoning Province has been more than 40%. At present, the bottom water of rivers is high, and some reservoirs and rivers exceed the flood season limit. Combined with the influence of recent heavy rainfall, the possibility of floods in the basins around Yanghe River, Liaohe River and Yalu River has increased.

  The Provincial Meteorological Bureau is still in a special working state of meteorological services for flood control and flood fighting in Raoyang River Basin, and sent a working group to Panjin to carry out refined meteorological services. On the 14th, it launched emergency response to rainstorm, and rolled out forecast and early warning service information, prompting to prevent secondary disasters caused by heavy rainfall, such as urban waterlogging, small and medium-sized river floods, mountain torrents, landslides, mudslides, farmland waterlogging, and crop lodging. It is suggested to do a good job in flood control management of river basins, reservoirs and towns and transfer key people to avoid danger.

  Dandong Meteorological Bureau carries out forecasting and early warning services for meteorological services in Yalu River basin and scenic spots; Anshan Meteorological Bureau provides meteorological services for flood control decision-making in key risk areas. At present, Xiuyan Manchu Autonomous County is carrying out personnel transfer. Panjin Meteorological Bureau focuses on the follow-up of the meteorological support service for drainage in the flood area around the Yang River, and updates the special report of meteorological and hydrological information with the Municipal Hydrological Bureau every four hours; Benxi Meteorological Bureau strengthens the risk early warning of geological disasters in mountainous areas.

  Qinghai: We should do our best to provide early warning service for the strongest precipitation since flood season.

  From August 13th to 14th, the strongest precipitation weather process occurred in the eastern part of Qinghai Province since the flood season. From 8: 00 on the 13th to 8: 00 on the 14th, the precipitation of 70 stations in the province exceeded 50 mm, and the precipitation center was in Xinbaozi Village, Shoule Town, Ledu, with the precipitation of 104.8 mm; The maximum hourly precipitation occurred in the office of Tsim Zadoga, which was 54.4 mm; The maximum precipitation in cities and towns appears in Hualong, which is 85.6 mm; The daily precipitation at Hualong, Huangzhong and Xunhua stations exceeded historical extremes.

  Qinghai Meteorological Bureau released the Important Weather Report on the 12th to start the emergency response to rainstorm. On the 13th, the Provincial Meteorological Observatory issued the yellow rainstorm warning signal, and jointly issued the meteorological risk warning of geological disasters and the meteorological risk warning of mountain torrents with the Provincial Department of Natural Resources and the Provincial Department of Water Resources respectively, suggesting that due to the superposition effect of precipitation and the lag of secondary disasters, the prevention of secondary disasters such as landslides, mudslides and floods in small and medium-sized rivers should be strengthened.

  According to the meteorological forecast and early warning, the leaders of the provincial party committee and the provincial government gave instructions respectively. The provincial government held two heavy precipitation meteorological service dispatching meetings, and the provincial defense index started the emergency response to flood control.

  In view of the impact of heavy precipitation on roads, railways, water conservancy, hydropower and other industries, meteorological departments at all levels in the province have strengthened duty, encrypted disaster risk judgment, timely and widely released early warning service information, implemented the "call" system, and tracked the disaster situation and service demand. By 8: 00 on the 14th, the province had issued 25 rainstorm warnings, 27 lightning warnings, 2 thunderstorm warnings, 1 hail warning, 7 geological disaster meteorological risk warnings and 10 mountain flood disaster meteorological risk warnings.

  Jilin: Implementing Call-to-Answer Service to Prevent Meteorological Disaster Risk

  On August 14th, a new round of heavy rainfall occurred in Jilin Province. After the national weather conference on the 14th, Jilin Meteorological Bureau made a request to deal with the precipitation process, and the business units of the provincial bureau should strengthen business guidance to Tonghua, Baishan and Changbai Mountain, and do a good job in basin forecasting and early warning services. Meteorological departments of cities and prefectures should, in light of local conditions, issue early warning signals in a timely manner, start emergency response in a timely manner, and strengthen upstream and downstream, left and right bank linkage and call service. Once sudden short-term heavy precipitation occurs, it is necessary to timely carry out "call service" for the affected areas.

  In the process of this precipitation, the area rainfall in Yalu River basin is relatively large, and the rainfall in southern Tonghua, southern Baishan and Changbai Mountain Nature Reserve is heavy and urgent. Heavy precipitation may cause geological disasters such as mountain torrents, mudslides and landslides, and it will have a great adverse impact on traffic, especially on outdoor activities in scenic spots such as Changbai Mountain in the east.

  In order to guide the public to prevent meteorological disasters and secondary disasters scientifically, on the 14th, the Provincial Emergency Management Department and the Provincial Meteorological Bureau jointly released popular science information on disaster prevention and mitigation, and made a detailed interpretation of the preventive measures for frequent meteorological disasters during the flood season.

  Inner Mongolia: Severe secondary disasters caused by heavy rains in Baotou and Hohhot.

  Since the night of August 13th, there has been heavy rainfall in Inner Mongolia Autonomous Region. As of 9: 00 on the 14th, there were heavy rains at 22 stations and 193 stations in the whole region. The maximum precipitation in 24 hours reached 228.9 mm and the maximum hourly precipitation reached 68.8 mm.. Flash floods and urban waterlogging occurred in Baotou, Hohhot, Erdos and Bayannaoer, and road traffic was blocked.

  In view of the heavy rainfall weather process, the Meteorological Bureau of the autonomous region made a forecast in advance, started the rainstorm emergency response, held a joint consultation with the emergency management department, and issued eight issues of meteorological forecast information, special reports of major meteorological information and hourly rain bulletin, and issued rolling rainstorm warning signals, lightning warning signals and meteorological risk warning of mountain torrents geological disasters.

  Hohhot investigated hidden danger points overnight, announced 62 urban waterlogging risk points, adjusted subway operation hours, and temporarily closed the zoo.

  The picture shows the news released by Inner Mongolia Radio and Television Station Tik Tok about the adjustment of operation time of Hohhot subway due to heavy rain.

  Baotou Meteorological Observatory continued to issue the rainstorm red warning signal at 23: 40 on the 13th, and Baotou Weather Modification and Meteorological Disaster Prevention Command started the first-level emergency response of rainstorm at 0: 00 on the 14th to guide and supervise the disaster prevention work in Qixian District and Rare Earth High-tech Zone in key areas affected by meteorological disasters. At 0: 30 on the 14th, the captain of Baotou Blue Sky Rescue Team received a live report on the rain situation from Baotou Meteorological Bureau, and posted a message through WeChat group to remind the team members in Tuyou, Guyang and Jiuyuan to be alert to mountain torrents. At 1 am on the 14th, a flash flood broke out in Jiuyuan District of Baotou City, and some people were trapped. After nearly two hours of emergency rescue, the trapped people were successfully rescued. (Wang Wei, Wang Xiaona, Gao Fei)

  Tianjin: Departments jointly defend against rainfall and secondary disasters.

  On August 14th, a rainy weather process occurred in Tianjin. From 6: 00 to 15: 00 on the 14th, the city’s average rainfall was 24.1 mm, and the maximum rainfall was 93.0 mm, which appeared in Huanxizhuang, Baodi District, and the rainfall is still continuing. In response to the weather process, Tianjin Meteorological Bureau took the "rain" as an order, acted ahead of time, and efficiently carried out departmental linkage work and forecasting and early warning services.

  Since August 11th, the Municipal Meteorological Bureau and the Municipal Emergency Management Bureau have held three meetings to jointly do a good job in urban waterlogging prevention. The Municipal Meteorological Bureau timely issued the "Meteorological Information Express" to the municipal party committee, the municipal government and the members of the municipal meteorological disaster prevention headquarters to help all departments take effective preventive measures in advance; Strengthen contact with Haihe Water Conservancy Commission, and issue the Haihe River Basin Weather Express to the Commission in a rolling way, so as to provide a basis for flood control and dispatching in the basin; Through the municipal emergency early warning information release system, five weather forecast tips and two meteorological early warning messages were released, with 35,000 emergency responders and 3.207 million people in short message service, and forecast, early warning and defense tips were released through new media and other channels. The meteorological department of Haihe River Basin continued to carry out joint defense of small watersheds to improve the ability of risk assessment and early warning service of meteorological disasters in the basin.

  In response to the flood control needs in the northern mountainous areas, the Municipal Meteorological Bureau strengthened its operational guidance to the Jizhou Meteorological Bureau and provided meteorological services for the prevention of geological disasters in mountainous areas. The Meteorological Bureau of Jizhou District focuses on strengthening the regional rainfall monitoring of geological hazards of mountain torrents, sharing the information of rain conditions and disasters with departments such as emergency management, water affairs, planning and natural resources, providing "calling for response" service to district committees and governments, and publishing meteorological service information to emergency contacts at all levels and the public through various channels.

  (Editor: Luan Fei)

I want to study how to prepare.

1. Vocabulary is the foundation.

You can buy a vocabulary book for postgraduate entrance examination. I used a vocabulary book published by New Oriental at that time. I read it back and forth many times, and I will spare at least half an hour to memorize words every day. In addition, I will read it with a word book in my spare time.

You don’t expect to improve your English instantly by memorizing words. It is a tool and needs long-term persistence. According to the scientific memory curve, the words memorized before need to be looked over frequently.

There is also an outline requirement for English for postgraduate entrance examination. The word book will mark the frequency of each word, and those that often appear as test sites need to be memorized.

2. Reading comprehension is the key.

Reading comprehension is what determines your final score in the English exam, so many people ask questions about sea tactics every day and do a lot of reading comprehension sets, but the correct answer rate is poor every time, and there is no progress in the end.

Before doing the problem, what we should do most is to find out where the inspection point of reading comprehension is and how to solve a kind of problem, instead of doing the problem by feeling. Generally, it can be divided into the following categories: examples, references, vocabulary, sentence comprehension, reasoning, theme, author’s attitude, judgment, details and so on.

No matter what kind of questions you encounter, don’t just rely on feelings, but find the answer in the article. The questioner will set some traps that people can easily believe. The reason why he is fooled is because he is taking the question for granted and thinks that he is the answer when he finds this sentence in the text. In fact, he has just entered the trap of the questioner.

The teacher has talked about the problem-solving method many times. Why do you still make so many mistakes? Because you didn’t follow the correct method. Every time you finish a problem, you should make a comparative summary. You should know the answering skills of a kind of problem. At first, it will be a little slow, but after you are proficient, you will improve your speed.

3. Make good use of real questions, take notes and learn to apply what you have learned.

Many people look for composition templates on the Internet. My experience is not to rely too much on templates. The best information is the real questions of previous years. You will find many good usages, good sentence patterns and advanced words in the process of doing the real questions, which are your best composition materials.

What you need to do is to carefully analyze each set of real questions, from words to sentences, from the method to the time, take notes, and then keep memorizing and strengthening them. It is enough to apply these good things to English for postgraduate entrance examination.

When musicians meet "young" movies,

The prism "Walking on the Waves" opens the musical journey of "Four Seas"


Whether it’s "Never See You Later", "Riding the Wind and Waves" or "Flying Life", the songs and music in Han Han’s movies always bring unexpected joy to the audience, which also makes the music of the movie "Four Seas" always highly anticipated. On December 24th, the film officially unveiled the OST special plan of "Music Tour of the Movie Four Seas" — — Invited different musicians, tailored several songs for the film and launched them one after another. A group of creative romantic musicians can’t help but expect what kind of sparks will collide with the young and bloody Four Seas.

On December 24th, the "Starting Concept Song" and "Walking on the Waves" written by Plateau, composed by Chen Hengjia and sung by Prism Band were officially released as the first single of the first chapter of the music journey — — Accompanied by melodious and soothing melody and emotional lyrics, blue sky, sea, highway and speeding motorcycle … … The impression that the movie "Four Seas" conveyed to the audience was also carefully unfolded again with the song. "Let me tread the waves, and the meteor can’t catch up with my engine." In the prism’s "Walking on the Waves", the teenagers in the film turned into cavalry who broke the wind and rushed out of this established world and rushed to the infinite scenery. When the motorcycle roared and the wheels rolled up dust, the story of A Yao, a teenager from South Australia Island, and a group of friends began.

The mysterious lineup of "Four Seas" music tour is expected.

"Set out for the Four Seas" Sing Young Adventures


As a young band established only five years ago, Prism has written and sung a lot of popular songs, among which there are many works widely sung by young people and students. Prism’s songs have both rock and folk characteristics, and they are popular. Just like their names, they radiate unique colors and light under the penetration of sunlight. And this uniqueness and youth also complement the temperament of Han Han’s film Four Seas — — Live up to your love and tread the waves.

I believe that these music can also lead the audience to embark on this journey of "singing for the whole world with the theme of youth".

The film Four Seas tells the story that Wu Renyao and Wu Renteng, the father and son of enemies who have not met again for many years, ran into orphans and brothers and sisters who had different ambitions while driving motorcycles, and also happened to meet all kinds of unreliable friends. With the roar of locomotives at night, A Yaoben’s lonely and calm life has since ushered in a huge wave, and several people have embarked on a journey of adventure together. On the first day of the New Year’s Day in 2022, let’s go to the four seas with Ayao.

The latest response from CDC!

On January 14th, National Health Commission held a press conference to introduce the prevention and treatment of respiratory diseases in winter in China and answer reporters’ questions.

Influenza is still the main respiratory disease at present.

Mi Feng, spokesperson of the National Health and Wellness Commission and deputy director of the Propaganda Department, said at the meeting that since the New Year’s Day, the number of fever clinics in medical institutions nationwide has fluctuated and declined. At present, the main respiratory diseases are influenza, the infection in Covid-19 is at a low level, and the medical services are generally stable and orderly.

Mi Feng said that since the New Year’s Day holiday, the cross-border tourism between North and South has been popular. Tourists from south to north enjoy different natural environment and cultural atmosphere. There is a great difference in climate between the north and the south, so we should pay attention to the weather changes and road safety at the destination and along the way. Continue to adhere to good hygiene habits such as wearing masks scientifically, washing hands frequently, ventilation frequently and keeping social distance, and identify respiratory symptoms in time and see a doctor in time.

Wang Dayan, director of the National Influenza Center of the Institute of Virology, China CDC, said that recently, the data of multi-channel monitoring system showed that after the New Year holiday, the epidemic situation in COVID-19 was still at a low level, among which the positive rate of Covid-19 in sentinel hospitals remained below 1%, and the proportion of JN.1 mutants showed an upward trend. According to experts’ judgment, due to the continuous input of JN.1 mutant, the gradual decline of domestic influenza activity and the decline of people’s immune level, the infection situation in Covid-19 may rebound this month, and JN.1 mutant will probably develop into the dominant epidemic strain in China.

Will patients who have been infected with influenza A be infected with influenza B again?

According to Wang Dayan, seasonal influenza includes subtype A H1N1, subtype A H3N2 and influenza B. The southern provinces of China have entered this influenza epidemic season since early October 2023 and the northern provinces since late October 2023. In the early stage, influenza A (H3N2) virus was the main epidemic strain. In the past five weeks, the proportion of influenza B virus in northern provinces continued to rise to 57.7%, and in the past three weeks, the proportion of influenza B virus in southern provinces continued to rise to 36.8%, and the proportion of influenza B virus in some provinces exceeded that of influenza A virus.

Influenza A and B viruses are distinguished by the sequence characteristics of their genes and proteins, and the seasonal influenza caused by them is difficult to distinguish in clinical symptoms. If we want to distinguish and identify influenza A virus or influenza B virus, we need to rely on pathogen typing.

In the same influenza epidemic season, there are usually different types and subtypes of influenza viruses, but the proportion is different. The immune response after getting influenza A cannot provide immune protection for influenza B. Even if you have had influenza A in this epidemic season, you may be infected with influenza B virus again. It is recommended that high-risk people be vaccinated as soon as possible.

Will respiratory diseases such as influenza A or B be repeatedly infected?

Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, said that winter is the season with frequent respiratory diseases, including influenza (influenza A, influenza B), Covid-19, respiratory syncytial virus, adenovirus and mycoplasma, etc. The immunity established by these pathogens after infection is not lasting and can be repeatedly infected, and the pathogens have no cross-protective immunity and can be infected simultaneously or alternately.

Repeated infection in a short time, because the immunity established by infection still exists, the condition is often milder; When different pathogens are infected at the same time, the disease may worsen, the respiratory immune barrier will be damaged after infection, and the risk of bacterial infection will increase, especially for the elderly, children and patients with basic diseases.

It is suggested that the symptoms of upper respiratory tract infection should be differentiated and diagnosed in time, and antigen or nucleic acid detection should be carried out. After the diagnosis is confirmed, targeted treatment can be carried out-

The flu can be treated with anti-influenza drugs such as oseltamivir or mabaloxavir; The elderly, children and patients with basic diseases should use anti-influenza drugs at an early stage.

If Covid-19 is infected, early application of anti-COVID-19 drugs can relieve symptoms, shorten the course of disease, reduce the risk of severe illness and hospitalization, and reduce the risk of further transmission.

How will respiratory diseases affect the cardiovascular system?

According to experts, whether it is bacterial, viral or mycoplasma infection, it may affect the cardiovascular system, especially the elderly, which needs attention.

The most common is myocardial involvement, which leads to myocarditis; Arrhythmias, such as premature beats and atrial fibrillation. For patients with existing cardiovascular diseases (hypertension, coronary heart disease, atrial fibrillation, heart failure, etc.), the disease may recur or worsen.

We should improve our ability of identification and prevention-

Once respiratory infection occurs, you should pay attention to rest and active treatment.

After the symptoms such as fever and runny nose have improved after the treatment of respiratory infection, chest tightness, shortness of breath, chest pain and even edema of lower limbs should be seen as soon as possible, and ECG, echocardiography, dynamic ECG, myocardial enzymes and heart failure indicators should be checked to determine whether cardiovascular diseases are involved.
