After returning to China, Wang Chengshu engaged in uranium isotope separation, which laid the foundation for theoretical research on uranium isotope separation in China and trained a theoretical research team. He contributed to the development of China's first atomic bomb, and remained anonymous until he studied China's first atomic bomb.
Anecdotes of characters
In the early 1960s, when the Soviet Union withdrew its experts, China's first gas diffusion plant to separate uranium isotopes faced a grim situation. Wang Chengshu put the national interest first and resolutely accepted the uranium isotope separation he had never done before. Since then, Wang Chengshu's name has quietly disappeared in Chinese physics circles.
Together with Wu Heqian, she started her silent work for the rest of her life. For decades, Wang Chengshu, together with workers, engineers and researchers, donated all his travel allowance, various awards and manuscript fees to the unit to buy books and stationery, and donated them to the uranium isotope separation branch of China Nuclear Society to carry out academic exchange activities under extremely difficult conditions.
In the difficult period of three years of natural disasters, in order to make up for the shortage of office funds, she bought a lot of paper for theoretical personnel.
