本文提出固体Ｃ_６０分子间合理的相互作用势模型，利用对称性适配函数描述了晶体场及取向模间耦合，并通过自由能的计算得出相交模及与实验相符的取向相变温度．
In this paper, the reasonable interaction potential model of solid C_60 is proposed. The symmetry adaptive function is used to describe the coupling between the crystal field and the orientation mode. The free energy is used to calculate the intersecting mode and the experimental phase transition temperature.
