 In 1960, Shi Ruwei (then director of the Institute of Physics, Chinese Academy of Sciences ) arranged for Li Fanghua to independently carry out electron diffraction research, so that she could take the scientific knowledge learned in the Soviet Union into China. "Single crystal electron diffraction" structure analysis research. In October 1982 , Li Fanghua went to the Department of Applied Physics, Osaka University, Japan as a visiting scholar (until May 1983), and carried two new domestically produced minerals: Yellow River ore and bastnaesium ore, hoping to use Japanese super-high resolution There are new discoveries in domestic minerals by the electron microscope.
