In the summer of, Qian Sanqiang (19 13- 1992), who has been in France for many years, will soon return to China. He bid farewell to his mentors, famous scientists Aurio and Curie, and Curie gave him an appraisal signed by them, which read: "In the past ten years, among those contemporaries who came to our laboratory and accepted our guidance, Qian Sanqiang has made great contributions to the scientific development of the motherland with outstanding achievements for 40 years, and he is an outstanding nuclear physicist in China.

Qian Sanqiang is from Xing Wu County, Zhejiang Province. My father is Qian, a famous linguist during the May 4th Movement. 1936, after graduating from Tsinghua University, Qian Sanqiang was sent to study in France the next year. During his stay in France, Qian Sanqiang was engaged in nuclear physics research in the Curie laboratory of the Institute of Radium Science of the University of Paris, with Marie? Curie's daughter Elena? Madame Aurio Curie. Their teachers cooperated with their students and made many new discoveries. 1945, it is generally believed that nuclear fission can only be divided into two fragments. Qian Sanqiang, his wife He and two French graduate students found that the nucleus of uranium was split into three pieces in about 300 fission after being hit by neutrons. They were very excited about this important discovery, but they didn't publicize it immediately, but went on with the experiment. At that time, there was no electronic computer, and every time an abnormal phenomenon was found, complicated calculations were needed. After a period of time, they observed more than 10,000 times, and finally proved at the end of 1946 that the nucleus of uranium can be split into two and three under the impact of neutrons. Not long after, He Hui Ze also observed the "four-split phenomenon" of uranium nucleus. These research results make people have a deeper understanding of nuclear fission and are praised by the French scientific community. It is considered to be the first important achievement of the Curie Laboratory and the Nuclear Chemistry Laboratory of the French Academy after the Second World War.

After the founding of People's Republic of China (PRC), Qian Sanqiang presided over the establishment of China's first nuclear science and technology base-Atomic Energy Research Institute, trained a large number of young and middle-aged business backbones, and personally participated in the first atomic bomb explosion test in June 1964+ 10/6, which made great contributions to the development of atomic energy in China.
