1in the autumn of 949, when People's Republic of China (PRC) was founded, Li Siguang was invited to be a member of the Chinese People's Political Consultative Conference (CPPCC). The ambassador of the Kuomintang government in Britain had received a secret order and publicly stated that he refused to accept the position of CPPCC, otherwise he would be detained. Li Siguang made a decisive decision and secretly returned to China in February 1949. Until1May 6, 950, Li Siguang finally arrived in Beijing.

For a long time, China has been regarded as an oil-poor country. When China began to implement the first five-year plan, Li Siguang, after carefully analyzing the geological conditions in China, was convinced that there should be abundant natural oil resources in the vast territory of China, and the key was to do a good job in petroleum geological exploration.

65438-0954 made a report on Petroleum Exploration Prospect in China from the Perspective of Tectonics, and pointed out three possible oil-bearing areas with the greatest prospect, namely Qinghai-Kangdian Belt, Alashan-Shanbei Basin and Northeast Plain-North China Plain, and put forward that Qaidam Basin, Sichuan Basin, Yishan Platform, A Ning Platform, North China Plain and Northeast Plain should be integrated first.

1in the spring of 955, he served as the chairman of the National Petroleum Investigation Committee to guide oil prospecting. Especially after the breakthrough in the Northeast Plain and the North China Plain, he strengthened China's confidence in its rich oil resources, and pointed out that the oil exploration theory in the New Cathaysian subsidence zone was reliable, which made an indelible contribution to the oil exploration in China.

2. Zhan Tianyou

In the seventh year of Guangxu in Qing Dynasty (188 1), he graduated from Yale University (Yale studied for three years at that time). Return to China immediately after graduation. After returning to China, he was sent to Fuzhou Shipping Bureau to learn to drive naval vessels, with excellent results and five military exploits.

1905- 1909 In order to develop commerce, the Qing government decided to build the Beijing-Zhangjiakou Railway. Zhan Tianyou was assigned to be responsible for road construction, first as chief engineer and general manager, then as general manager and chief engineer. This road runs from Beijing to Zhangjiakou and across the Du Jun Mountains. The terrain is steep and the project is extremely arduous. It is about 200 kilometers long and is the main road leading to the northwest.

In order to compete for the right to build roads, Britain and Russia were deadlocked, and the Qing government decided to build it by itself, but it lacked confidence. Foreigners are talking about China's inability to complete the road construction project. Zhan Tianyou said: "China has a vast territory and rich resources. It is shameful to rely on outsiders for all the work along the way!" In the face of foreigners' sarcasm, he led all road builders to face difficulties with fearless spirit. Qi Xin won glory for his country.

It took only four months from survey to opening to traffic, two months ahead of schedule. Cixi was very happy to sit on this special train and specially summoned Zhan Tianyou. In order to show Zhan Tianyou's contribution to road construction, Cixi gave Zhan Tianyou the jewels she carried with her. Zhan Tianyou only took a clock as a souvenir, and all the rest were given to the road builders.

3. Hua

From 65438 to 0946, Hua was invited to give lectures in the United States and was hired as a tenured professor by the University of Illinois. His family also settled in the United States, with a house and a car, and their life was very comfortable. At that time, many people thought that Hua would never come back. The birth of the new China touched China's love for the motherland.

1950, he resolutely gave up his comfortable life in America and returned to his motherland. He also wrote an open letter to China students studying in the United States, urging them to return to China to participate in socialist construction. In his letter, he confessed his love for China: "Friends! Although Liangyuan is good, it is not the hometown of longevity. Go back to Xi ... For the sake of the nation, we should go back ... "Although mathematics has no national boundaries, mathematicians have their own motherland.

Hua returned from overseas and was warmly welcomed by the party and people. He returned to Tsinghua campus, was appointed as the head of the Department of Mathematics, and was soon appointed as the director of the Institute of Mathematics of China Academy of Sciences. Began the real golden age of his mathematical research. He not only made remarkable achievements that attracted worldwide attention, but also trained a large number of mathematical talents. He devoted a lot of efforts to the research, experiment and popularization of applied mathematics.

According to incomplete statistics, Hua * * * has published important mathematical papers 152, 9 mathematical works and1/mathematical popular science works for decades. He was also elected as a foreign academician of the Academy of Sciences and an academician of third world scientists. From junior high school graduation to people's mathematician, Hua has gone through a tortuous and brilliant life path and won great honor for his motherland.

4. Deng Jiaxian

Deng Jiaxian is an academician of China Academy of Sciences and a famous nuclear physicist. 1 949 65438+1October1,New China was founded. Facing the ruined land of China, the Party and people have devoted great enthusiasm to the construction of this new society. With a pure heart, Deng Jiaxian broke through many obstacles from the United States on the other side of the ocean and returned to his beloved land.

At that time, the United States gave him generous treatment and hoped that he could stay in the United States, but he abandoned the generous life of luxury food and devoted himself to the ruined motherland without hesitation. 1958 when he learned that he was going to participate in the research of the atomic bomb, he was so excited that he was willing to remain anonymous for life that even his wife needed to hide it. After five years' efforts, China successfully exploded the first atomic bomb in June 1964+00!

Since then, China no longer has to fear the nuclear deterrence of other countries. From that moment on, China people's backs were completely straight! It can be said that Deng Jiaxian has given the Chinese nation unprecedented confidence! Perhaps the best way to pay homage to such a noble person is to remember his name deeply!

5. Feng Ru

19 10, Feng Ru designed and manufactured an airplane with better performance in the United States. Flying at an altitude of over 700 feet and a speed of 65 miles per hour, it broke the world record of the first international flight competition held in France in 1909 and won the Excellence Award, which once again enabled China people to surpass the West in aviation technology. Feng Ru has become a world-recognized aircraft designer, manufacturer and pilot.

Revolution of 1911 broke out. Feng Ru resolutely took part in the revolutionary army and devoted himself to the revolutionary torrent of overthrowing the Qing Dynasty and establishing the Republic. The revolutionary army appointed Feng Ru as the captain of the army plane, and authorized Feng Ru to organize a flight reconnaissance team to cooperate with the Northern Expeditionary Army to carry out air strikes against the Qing army stationed in the north.

1965438+On August 5, 2002, with the approval of the provisional government of the Republic of China, Feng Ru made his second flight show in the suburbs of Guangzhou. An accident happened during the flight. On September 24th, 2002, people from all walks of life in Guangzhou held a memorial service at the plane crash site in Feng Ru. According to Feng Ru's wishes, his body was buried on the left side of Huanghuagang Martyrs' Tomb under Baiyun Mountain in the eastern suburb of Guangzhou. Feng Ru, together with the heroes who founded the Republic of China, is remembered by people all over the country.

Feng Ru's life is a life of struggling for the rise of China. He devoted his short and lifelong energy to the aviation industry of his motherland. Before he died, he never forgot to let his assistants inherit his last wish and improve China's airplane industry.
