 In February 2003, she received the L'Oréal-UNESCO Awards for Women in Science Award . Li died on January 24, 2020 in Beijing . Personal life Li was married to fellow physicist Fan Haifu While studying in Japan in the 1980s, Li Fanghua summarized new experimental rules and developed a method for determining the position of light atoms. On this basis, after returning to China, she proposed a new image contrast theory: "pseudo-weak phase object approximation". This theory clarified the relationship between image intensity and crystal thickness for the first time, and revealed the law of changes in the intensity of different atomic images. , Is the theoretical basis of the above-mentioned image processing technology. Under the guidance of this theory, Li Fanghua et al. observed lithium atoms in crystals for the first time experimentally. In addition, she participated in the early research of high-temperature superconducting materials by means of high-resolution electron microscopy, and was one of the first groups in the world to report the presence or absence of commensurate modulation structures of bismuth superconductors. .
