摘要

以对应状态原理计算混合物的热力学性质是一较好的方法

为此必须计算混合物的假临界常数。本文利用统计力学基本关系式

作某些简化假设

给出了一种简便的非极性和微极性混合物假临界常数的计算方法。并与Lee-Kesler方法进行了详细比较。对一些实际混合气体的压缩因子进行了计算

与Lee-Kesler法和实验数据皆能很好地一致。

Abstract

With the aid of fundamental correlations of statistical mechanics and some assumptions

a simple method for calculating pseudocritical constants of mixtures containing nonpolar and slightly polar components is proposed in this paper. A detailed comparison of pseudocritical constants by this method with that by Lee-Keslers rule has been made. Finally

using this method together with Lee-Kesler tables

compressibility factors for some gas mixtures have been calculated

obtaining good agreement with experimental data.
