基于胞腔模型和无热溶液理论推导超额热力学函数和液相活度系数方程

Equations of excess thermodynamic function and activity coefficient based on cell model and athermal solution theory

基于胞腔模型和无热溶液理论导出相应的超额热力学函数和液相活度系数方程。同时还给出了由该活度系数方程计算出的１４个二元体系的汽液平衡数据，结果是满意的。

he equations of excess thermodynamicfunction and activity coefficient are derived onthe basis of simple cell model and athermal solution theory. The vapor-liquid equilibriumdata for fourteen binary systems are obtainedusing the activity coefficient equation. The results are fairly satisfactory.
