In October, Guangzhou was liberated and public schools opened, and she transferred to the Department of Astronomy at Sun Yat-Sen University.
But because of frequent suspension of classes and drumming and going to the street to do political propaganda, she wanted to change to a school with more studies.
Her research content includes:[7] In the early 1960s, Li Fanghua first carried out electron diffraction in China to determine the structure of a single crystal.
[8] While studying in Japan in the 1980s, Li Fanghua summarized new experimental rules and developed a method for determining the position of light atoms.
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.
[8] The research team led by Li Fanghua first discovered and reported the almost continuous transition process between quasicrystals and crystals, and she gave a theoretical explanation.
[8] For the newly developed field emission electron microscope, Li Fanghua proposed a new research direction for measuring crystal defects with atomic resolution.
