摘要
从理论和实际应用两个方面对热力学基本关系式的使用条件进行了探讨,指出基本关系式主要运用于只做体积功,没有相变和化学变化的封闭体系的任意过程;并指出它在特殊过程中的运用。
In this paper, the applicable conditions of the fundamental equations of thermodynamics are discussed theorically and practically. It is pointed out that the fundamental exquations are mainly used in the arbitray process in a closed system which produces only expansion work without causing the phase transformation and chemical reaction, and that the fundamental equations are used in a particular process.
