The deeds of famous scientists in China

Qian Sanqiang (19 13— 1992), formerly known as Qian Bingqiong, male, nuclear physicist and academician of China Academy of Sciences. Father Qian is a famous linguist in modern China.

He is a second-generation student of the Curies, and together with his wife He, he is called "the Curies of China" by the west. He is the organizer and chief designer of China's nuclear weapons development and the founding father of China's "two bombs and one satellite".

Engaged in nuclear physics research in his early years and made outstanding achievements in "nuclear fission". He is an advocate of many interdisciplinary and interdisciplinary subjects. He discovered the phenomenon of triple division and quadruple division of heavy nuclei, and made a reasonable explanation for the triple division mechanism, which deepened the understanding of fission reaction.

He has made great contributions to the establishment of China's atomic energy science and the "two bombs" research, and to the establishment and development of China Academy of Sciences, especially in establishing and perfecting academic leadership, cultivating scientific and technological talents, conducting international academic exchanges, and organizing and coordinating major scientific research projects.

The main founder of China's atomic energy industry is known as "the father of China's atomic energy science" and "the father of China's two bombs". An outstanding scientist.

2. Qian Xuesen

Qian Xuesen (191.12.1-2009.10.31), a native of Lin 'an County, Hangzhou City, Zhejiang Province, is an outstanding patriotic scientist in China.

Party member, an outstanding producer in China, a loyal fighter, an outstanding scientist at home and abroad, the founder of China's space industry, and one of the winners of China's two bombs and one satellite meritorious medal.

1In August, 935, Qian Xuesen went to the United States to study aviation engineering and aerodynamics as a public student. Before returning to China, he was the director of the supersonic laboratory of California Institute of Technology and the director of the Jet Propulsion Research Center.

1949 Mid-Autumn Festival, the good news of the founding of New China spread to the other side of the ocean. Qian Xuesen and a dozen overseas students from China poured out their hearts while enjoying the moon. On this beautiful day of full moon reunion, Qian Xuesen sprouted the idea of returning to China as soon as possible to serve the motherland.

Just as Qian Xuesen was actively preparing to return to China, the Korean War broke out, which set off a crazy counter-current in the United States. Qian Xuesen was suspected of being involved in the case of Weinbaum, secretary of Marxism-Leninism in the college. The US government decided to disqualify him from participating in confidential research and accused him of being an American-made party member and entering the country illegally.

Qian Xuesen formally applied to return to China while refuting the accusation of the United States. Just two days before he planned to leave Los Angeles, the immigration suddenly ordered him not to leave the United States, and the customs detained all his luggage.

From 65438 to 0955, after Premier Zhou Enlai's continuous efforts in diplomatic negotiations with the United States-even including the release of 1 1 American pilots captured in the Korean War, Qian Xuesen received a notice from the US Immigration Bureau on August 4, 1955 that he was allowed to return to China.

1September 1955 17, Qian Xuesen's wish to return to China finally came true. On this day, Qian Xuesen, his wife Jiang Ying and a pair of young children boarded the ship "President Cleveland" and embarked on the journey of returning to the motherland. 1On October 8th, Qian Xuesen's family finally returned to the haunted motherland and hometown.

Thanks to Qian Xuesen's return to China, China's missile and atomic bomb launches were at least 20 years ahead of schedule.

3. Deng Jiaxian

Deng Jiaxian (1June 25th, 924-1July 29th, 986), member of Jiu San Society, academician of China Academy of Sciences, famous nuclear physicist, pioneer and founder of nuclear weapons development in China, has made important contributions to the research and development of nuclear weapons and atomic weapons in China.

1924 was born in a scholarly family in Huaining County, Anhui Province. From 65438 to 0935, he was admitted to Zhicheng Middle School. During his schooling, he was deeply influenced by the patriotic national salvation movement. 1937 After the fall of Beiping, he secretly attended the anti-Japanese party.

Later, under the arrangement of my father Deng Yizhe, I went to Kunming with my sister, and 194 1 was admitted to the Physics Department of Southwest Associated University. 1948 to 1950, studied at Purdue University, USA, and obtained a doctorate in physics. In the year of graduation, he resolutely returned to China. ?

Deng Jiaxian is the main organizer and leader of China's nuclear weapons research and development. Deng Jiaxian has been leading many scholars and technicians in the front line of weapons manufacturing in China, successfully designing China's atomic bomb and hydrogen bomb, and leading China's national defense and self-defense weapons to the advanced level in the world.

1982 won the first prize of the National Natural Science Award, 1985 won two special prizes of national scientific and technological progress, 1986 won the title of national model worker, 1987 and 1989 won the special prizes of national scientific and technological progress 1 respectively.

1999 was posthumously awarded the "Two Bombs and One Satellite Meritorious Medal". Because of his great contribution to China's nuclear science, he is called "Two Bombs".

4. Li Siguang

Li Siguang (1889101October 26-1971April 29), formerly known as Li, was born in Huanggang, Hubei, Mongolian, geologist, educator, musician, social activist, geomechanics in China and modern China.

In 2009, the first batch of outstanding scientists and founding fathers who made outstanding contributions to the development of new China after the founding of New China were elected as one of the 100 people who moved China since the founding of New China.

Li Siguang1910 graduated from Osaka Higher Technical School in July; 19 1 1 year as the minister of industry of Hubei military government; 1928 1 month, as the director of the institute of geology, academia sinica; 1948 was elected as an academician of academia sinica;

1950 served as vice president of China Academy of Sciences in May; 1951April was elected as the vice chairman of the Executive Committee of the World Association of Scientists; 1September, 952, born in * * *, Ren Zhonghua, Minister of Geology; 1955 was selected as an academician of China Academy of Sciences;

1958 President of China Association for Science and Technology in September; 1April, 969, was elected as the 9th Central Committee member of China * * * Production Party; 1In August, 970, he was appointed as the leader of the State Council Science and Education Group.

Li Siguang founded geomechanics, which made great contribution to the development of China petroleum industry. In his early years, he made exquisite research on Odonata fossils and their stratigraphic stratification, put forward the existence of Quaternary glaciers in eastern China, established new concepts of geomechanics and tectonic system, established the concept of tectonic system, and founded geomechanics school.

It is pointed out that the three subsidence zones of the new Cathaysian tectonic system have broad prospects for oil exploration, and a way to predict earthquakes by combining active tectonic research with in-situ stress observation is created.
