固体C_（60）中取向运动模型与结构相变温度的计算

Molecular Orientational Motion Models and Calculation of Structural Phase Transitions Temperature in Solid C_(60)

提出了不同温度范围内固体Ｃ_（６０）分子取向运动模型，从微观上探索了取向相变发生的原因，并根据这些模型计算了面心立方及取向玻璃态的转变温度Ｔ_ｃ及Ｔ_ｇ，结果与实验颇相符合。

The molecular orientational motion models in different regions of temperature have been proposed in solid C_(60) to study the mechanism of orientational phase transitions. In terms of these models, the temperatures T_c and T_g are calculated for the transition from facecentred-cubic to simple-cubic lattice and the glass transition respectively, which agree well with the results of experiments.
