1956, Rong Guotuan defeated Ichiro Ogimura, the main force of the Japanese table tennis team who was visiting Hong Kong, 2-0. The following year, he represented the FTU table tennis team in the territory-wide competition and won the men's singles, doubles and men's team championships in one fell swoop. This year, he returned to Guangzhou with his father and was admitted to Guangzhou Institute of Physical Education. 65438-0958, represented Guangzhou in the National Nine Cities Table Tennis Championships and won the national men's singles championship. In terms of technical methods, Rong Guotuan developed China's traditional left-pushing and right-attacking method, and successfully created new technologies such as serving and twisting. After being selected for the national team, he worked hard on the fast-break style of direct shooting. He is good at serving, pushing, pulling, cutting, rubbing and forehand and backhand attacks, and soon formed a technical style of "fast, accurate, ruthless and changeable". 1959 In March, the 25th World Table Tennis Championships was held in Dortmund, West Germany. In men's singles, Rong Guotuan finally competed with the Hungarian veteran Sido, who won the world championship nine times. In view of Sido's fat figure, he served both long and short, cooperated with pull-ups and increased the angle of killing. He lost one game first and then won three games in a row, defeating Sido. Rong Guotuan's name was first engraved in St.? At the Brad Cup, she was the first China table tennis player to win the world championship. 1961April, in the men's team final of the 26th World Table Tennis Championships held in Beijing, Rong Guotuan wept at 3: 4 in China. Qiu Zhonghui, a female player, asked him after seeing it. He replied that he lost two games, and immediately said excitedly, "Life is rare, when will you wait?" He pulled himself together, swung into battle, defeated the Japanese player Hoshino, who is known as the "lion", defeated the Japanese team 5-3, and won the Swahilin Cup for the first time, making contributions to the country. From then on, the famous saying "there are few beats in life" spread.
Zhan Tianyou (1861April 26, 2009–1965438+April 24, 2009), a native of Nanhai, Guangdong Province, was the first railway engineer in China, and was responsible for the construction of Beijing-Zhangjiakou Railway and other projects, including "China Railway".
1905, the Qing government decided to build the first railway in China-Jing-Zhang Railway. Both Britain and China wanted to intervene, but their attempts failed because of the strong opposition of the Russian people. The British and Russian envoys said in a threatening tone: "If the Beijing-Zhangjiakou Railway was built by Russian engineers themselves, it has nothing to do with Britain and Russia." They think that, in this way, it is impossible to build a railway in China. At this critical moment, Zhan Tianyou accepted this arduous task without hesitation and was solely responsible for the construction of the Beijing-Zhangjiakou Railway. News came that some imperialists and British newspapers sarcastically said, "The engineer who can build this railway in China has not been born in the womb! China people want to build railways without foreigners, even if it is not a dream, it will take at least 50 years. " They even attacked Zhan Tianyou, the general manager and chief engineer, for being "arrogant" and "overreaching". Under pressure, Zhan Tianyou insisted on not appointing foreign engineers, and said: "China is vast and rich in resources, and I feel ashamed to rely on outsiders all the way to work!" "China has awakened, and China people will use their own engineers and their own money to build railways."
1In August, 905, the Beijing-Zhangjiakou Railway was officially started, and intense exploration and route selection began. Zhan Tianyou personally led the students and workers, carrying benchmarks and theodolite, running around the rugged mountains day and night. One evening, the fierce northwest wind roared in Badaling area, whizzing past with dust, which made people unable to open their eyes. The survey team finished the work in a hurry, filled in the survey figures and climbed down from the rock wall. Zhan Tianyou took the notebook, looked at the figures and asked doubtfully, "Is the data accurate?" ? "Almost," replied the surveyor. Zhan Tianyou said seriously: "The first requirement of technology is accuracy, and there can be no ambiguity or rashness. Statements like' probably' and' almost' will not be said by engineers. " Then, he picked up the instrument, braved the wind and sand, climbed to the rock wall again with difficulty, carefully surveyed it and corrected a mistake. When he came down, his lips were purple with cold.
Soon, exploration and construction entered the most difficult stage. At Badaling and Qinglong Bridge, there are overlapping mountains and steep walls hanging rocks, and four tunnels will be opened, the longest of which is more than 1000 meters. After accurate calculation, Zhan Tianyou decided to adopt the method of sectional construction: simultaneously drilling from the north and south ends of the mountain, opening a large well in the middle of the mountain, and then drilling from the north and south ends in the well. This not only ensures the construction quality, but also speeds up the project progress. When digging a hole, I dug a lot of stones by hand and picked out the spewing spring water one by one. Zhan Tianyou, as the chief engineer, has no shelf. He digs stones and carries water with the workers, and his face is covered with mud and sweat. He also encouraged everyone to say, "The Beijing-Zhangjiakou Railway is the first railway that we built with our own people and our own money. The eyes of the whole world are watching us, and we must succeed! " "No matter success or failure, it is definitely not our own success or failure, but the success or failure of our country!"
In order to overcome the difficulty of driving on steep slopes and ensure the train to climb up Badaling safely, Zhan Tianyou creatively used the principle of "turn-back line" to design a herringbone line on the steep Qinglong Bridge section in mountainous areas, which reduced the tunnel excavation and slope. When the train arrives here, it will cooperate with two high-powered locomotives to push and pull to ensure the safety of the train uphill.
Zhan Tianyou once put forward three requirements for the whole project: "less money, good quality and quick completion". After several struggles by workers, the Beijing-Zhangjiakou Railway was finally opened to traffic in September 1909. It was originally planned to be completed in six years, but it was completed four years ahead of schedule, and the project cost was only one-fifth of that estimated by foreigners. Some European and American engineers paid tribute to Zhan Tianyou after visiting by bus. But Zhan Tianyou said modestly: "This is the strength of more than 10,000 employees of Beijing-Zhangjiakou Railway, not my personal credit. Glory should belong to everyone. "
Li Siguang, (1889- 197 1), a Mongolian, was born in a poor family in Huanggang county, Hubei province on October 26th. He studied in a private school taught by his father Li Zhuohou since childhood. 14 years old, bid farewell to his parents and came to Wuchang alone to apply for higher primary schools. When filling in the registration form, he mistook the name column for the age column, wrote down the word "fourteen", then changed the word "ten" to "Li", followed by the word "light", and from then on he got the good name of "Li Siguang".
Li Siguang's greatest contribution is to establish geomechanics, study the phenomenon of crustal movement from the mechanical point of view, explore the laws of geological movement and mineral distribution, the characteristics of the new Cathaysian tectonic system, and analyze the geological conditions in China, which shows that there must be oil on the land of China. Theoretically, it overturns the conclusion that China is poor in oil and affirms that China has good oil storage conditions. After listening to the report carefully, Mao Zedong and Zhou Enlai supported his point of view, and according to his suggestion, they started a large-scale oil survey in Songliao Plain and North China Plain. From 65438 to 0956, he personally presided over the oil survey and exploration. In a very short period of time, he successively discovered Daqing, Shengli, Dagang, Huabei, Jianghan and other oil fields, and made immortal contributions to China's oil industry. From the late 1950s to the 1960s, the exploration departments successively discovered the major oilfields such as Nianji Oilfield, Dagang Oilfield, Shengli Oilfield and Huabei Oilfield. When the national construction was in urgent need of energy, rolling oil appeared. In this way, not only did China get rid of the "poor oil" hat, but Li Siguang's original geomechanics theory was also the most powerful proof.
Liu Xiang, a Shanghainese, was born in 1983.7. 13.
In the 2004 Athens Olympic Games, he tied the world record held by British star colin jackson with 12 seconds and 9 1. This gold medal is the first track and field gold medal won by China male athletes at the Olympic Games, which has written a new history of track and field in China!
Liu Xiang's running shows that yellow people can fly. Ethnography is like an anesthetic. While Japanese football, Korean football, Japanese men's swimming and marathon are striding forward quietly, China football, track and field, men's swimming and many other events are still idling to kill time under the comfort of this anesthetic. Liu Xiang's contribution to China sports is a breakthrough in track and field short-distance events; For the world sports, his contribution lies in breaking through the prejudice of "ethnology", as he himself said: "Whoever says that China people can't enter the top 8 in the world, I am the world champion!" Moreover, Liu Xiang tied the world record, saying that yellow people can not only fly, but also fly as fast. Moreover, Liu Xiang has a bright future because of its youth, especially in 2008. We expect Liu Xiang to break through 0.0 1 s again-it seems that this is a quick and easy thing-so yellow people can not only fly, but also fly faster.
Yuan Longping 1 930 September1. People from De 'an County, Jiangxi Province.
In the early 1960s, Yuan Longping led students to practice in rural areas and witnessed the current situation of food shortage and people's living difficulties in rural areas. He is determined to start with improving crop varieties, explore the road of developing agriculture through science and technology, and fight hunger and famine.
According to the theory of "asexual hybridization" of Michulin and lysenko, teaching and scientific experiments were carried out. According to their classical theory and the general international view at that time, rice, as a self-pollinating plant, has no heterosis and the experiment is meaningless. Yuan Longping had doubts about these theories, and it took a lot of courage to discuss them with Mendel and Morgan's theory of genetic contamination, which was criticized at that time.
1964, Yuan Longping accidentally discovered a natural hybrid rice with very strong advantages, which gave him great inspiration.
He conceived to use the male sterility of rice to produce hybrid seeds by cultivating "three lines" of sterile line, maintainer line and restorer line instead of artificial emasculation, and published "Rice Male Sterility", an epoch-making paper on hybrid rice research, in Science Communication No.4 1966 published by China Academy of Sciences.
According to the western world, hybrid rice is "Oriental magic rice". His achievements not only solved the problem of eating in China to a great extent, but also were regarded as the magic weapon to solve the world hunger problem in the next century. Internationally, hybrid rice is even regarded as the fifth great invention of China after the four great inventions, which is called the "second green revolution".
