活动性系数(activity coefficient)这一名词,常见于一般化学书籍中。在理论方面最主要的是根据Debye-Hückel 的完全游离说和电解质游子相互吸引说。活动性系数的涵义,尤其是这系数和Arrhenius 学说中的游离度(degree ofionization)有何区别,可参考一般化学教本(例如拙著定性分析原理pp.30—33),本文仅介绍游子活动性系数的测求简法。 Activity coefficient (activity coefficient) the term commonly used in general chemistry books. In theory, the most important thing is to say according to Debye-Hückel’s completely free say and electrolyte wander attract each other. The meaning of the activity coefficient, especially the difference between this coefficient and the degree of ionization in the Arrhenius theory, can refer to the general chemistry textbook (for example, the principle of qualitative analysis pp. 30-33). This article only introduces the activity coefficient Jane
