逸度和逸度系数推导计算中的常见误区

The Common Mistakes in Derivation and Calculation of Fugacity and Fugacity Coefficient

分别以某《物理化学教程》教材中关于逸度和逸度系数的错误计算为例,介绍了逸度系数和逸度公式推导过程中易犯的错误,并给出了的正确推导方法,同时分析了错误产生的原因。指出是由于公式推导过程中对于非理想气体化学势的状态混淆不清造成。并以某非理想气体为例,分别采用正确的和错误的公式进行计算验证。希望以此引起广大教研人员和学习者的注意。

There are some mistakes in some a textbook of 〈physicalchemistry course〉. Take those errors as example, introduced the easy mistakes in the derivation of fugacity and fugacity coefficient. The right derivation courses were given in the paper, as well as the origin of mistakes. That is the confused understanding of the potential energy state of imperfect gas. Take some imperfect gas for instance, tested the wrong and the correct formulas mentioned in the paper. It should cause the attention of vast teachers and students.
