摘要

混合工质汽液相平衡学术内涵丰富且应用广泛，而混合规则是决定混合物性描述准确与否的关键因素。综述了具有代表性的混合规则，包括原始的二次型、非二次型、密度型、状态方程-超额自由能型等混合规则，评价了其在流体汽液相平衡的描述能力，辅以数学推导介绍了其发展的动机及存在的优劣，以期对将来混合规则发展提供思路。

Abstract

The vapor-liquid phase equilibrium data are the critical thermophysical property in chemistry industry. Since the mixing rules are the key factor to calculate the vapor-liquid equilibrium property of mixtures

they have been studied for more than one hundred years. The representative mixing rules are summarized

including the original quadratic form

non-quadratic type

density type

state equation-excess free energy type and other mixing rules. The ability to describe the vapor-liquid equilibrium in the fluid is evaluated. The mathematical derivation of these mixing rules are given in an understandable way and the motivation of their development and their strengths and weaknesses are analyzed.
