摘　　要：依据化学势的基本原理，采用经典的化学热力学实验方法，测定苯-乙醇体系在不同温度下的活度系数，并求得其超额自由能、超额焓、超额熵等超额热力学函数，从而设计出一种测定非电解质溶液二元体系超额热力学函数的实验方法，应用于物理化学实验教学。该实验方法简便，结果准确。According to the basic principle of chemical potential, the experiment adopts classic chemical thermody- namics method, determines activity coefficient of benzene- alcohol system in various temperatures and works out seve- ral excess thermodynamics functions such as excess free energy, excess enthalpy, excess entropy and so on. There- fore, it will devise a kind of method that can determine non- electrolytic solution＇s binary- component system excess thermodynamics function. This method will be applied to physicschemical experimental teaching. It is convenient, and has an accurate result.
