摘要：

从Barber－Henderson的硬球微扰理论出发，运用幂级数形式的经向分布函数和分段的势能函数导出了马丁-侯状态方程．推导过程中导出了一种理论式，其计算P－V－T性质的精确度与马丁-候原式相当．理论式的常数与分子微观参数有确定的函数关系．

关键词: 状态方程, 微扰理论, P-V-T性质

Abstract:

 By using a power series form of radial distribution function, Martin-Hou equation of state is derived theoretically by using an approximate form of Barker-Henderson’s hard particle perturbation theory. In this derivation, a theoretical form of the Martin-Hou equation is obtained. It has similar form and the same abilities to predict P-V-T properties as the Martin-Hou equation. The constants of the theoretical expressions have functional relationships with some molecular parameters.
