| 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. |
