摘　　要：With many special physical and chemical characteristics, the fullerenes in cage-likestructure (C₆₀, C₇₀,etc.)have become a subject in the front fields of material science.According to Ref.[1], the C₆₀and C₇₀ molecules may be in two kinds of crystal struc-tures at room temperature. When deposited on a gold （Au） film, the molecules arein fcc structure(α=1.428×10^-9m), and when deposited on a glass surface, themolecules are in hcp structure (α=1.005×10^-9m, c=1.641×10^-9m). The phase transi-tions have been observed at different temperatures. Moreover, the C₆₀/C₇₀
