| 摘 要： | 采用Ｗｏｎｇ和Ｓａｎｄｌｅｒ混合规则，将ＰＲＳＶ立方型状态方程与ＵＮＩＦＡＣ活度系数模型相结合，给出一种预测混合物相平衡热力学性质的方法，并用５４个二元体系和９个三元体系的实验数据做了检验，结果表明，该法可以较好地预测二元及三元体系的汽液相平衡。

| Abstract: | method for predicting vapor-liquid equilibria of mixtures was presented using the mixing rule of Wong and Sandler,PRWV combined with UNIFAC. Results for 54 binary systems and 9 ternary sys-tems show that the new method can give good prediction for binary as well as ternary systems. |
