 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 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. Li Fanghua used the phase sub-strain field to derive some formulas reflecting the relationship between the quasicrystal and the crystal, and on this basis, proposed a new method to determine the structure of the quasicrystal, as well as the determination of the local phase sub-strain in the quasicrystal. method. And successfully applied to Al-Cu-Li and Al-Mn-Si quasicrystals. .
