编辑同志: 近年来,在一些系统的活度计算中,曾多次地用到各种形式的变通的Gibbs-Duhem关系式,在某些情况下,由于遇到了图解积分的困难,影响了活度系数的完整计算,限制了一些新方法的推广和应用。本方法试图从一般的变通式入手,分析可能出现图解积分困难的各种情况, Editorial Comrades: In recent years, various forms of modified Gibbs-Duhem relations have been used on many systems of activity calculations in some cases, and in some cases, the difficulty of graphical integration has been affected, affecting live The complete calculation of degree coefficient limits the popularization and application of some new methods. This method attempts to start from the general variation, analyze various situations that may appear difficult to integrate graphically,
