van der Waals型立方状态方程中的混合规则——Ⅰ多参数vdW单流体混合规则

Mixing Rules for van der Waals Type of Cubic Equation of State Ⅰ Multiparameter mixing rules of vdW one-fluid type

近十几年来，为了将简单的 ｖａｎ ｄｅｒ Ｗａａｌｓ型两参数立方状态方程的使用范围扩大到复杂混合物体系，发展起了一系列混合规则，这些混合规则可分为两类，一类是ｖｄＷ单流体多参数混合规则，另一类称之为状态方程／过量吉布斯自由能模型（ＥＯＳ／ＧＥ）．本文介绍第一类混合规则中有代表性的、重要的混合规则，并扼要讨论各混合规则的适用范围及存在问题．

In the last decade, several mixing rules were developed to extend the applicability range of the simple two parameter van der Waals type of cubic equation of state to complex mixtures. These mixing rules can be divided into two classes. The one is the muliparameter mixing rules of the van der Waals one-fluid type, the other is the equation of state/excess Gibbs free energy model(EOS/GE). In this manuscript, we review the representative and important ones in the first class of mixing rules and briefly discuss the range of applicability for every mixing rule presented.
