摘　　要：物理化学的宏观部分是以热力学三个定律为基础建立起来的，其中有八个状态函数，Ｕ、Ｈ、Ｓ、Ａ、Ｇ、Ｔ、Ｐ、Ｖ，通常称它们为热力学八大状态函数．这八个状态函数之间相互结合，构成了热力学函数间的各种关系式．本文对这些热力学函数间所建立的各种关系式和相互转换的法则进行了规律性的总结，提出了解热力学函数间关系式证明题的一般思路、方法和步骤．Three laws of thermodynamics were the major content in the macroscopic parts of physical chemistry. Many relations were produced by the combination of the eight state functions, i.e., U, H, S, A, G, T, P, V. In this work, a useful method was proposed to resolve the complicated proving questions in the macroscopic parts of physical chemistry. The method was useful for the student to understand the eight state functions as well as the relations conversed from them.
