| 摘 要： | 自发过程是化学热力学一个极为重要的基本概念,但是各教材对其定义历来不尽一致,对自发过程判据的阐述也不十分清楚,给教学带来了一定困难。鉴于此,讨论了迄今为止几种自发过程定义的优缺点,分析了造成自发过程定义不统一的主要原因,讨论了熵判据可作为自发过程判据的条件。

| Abstract: | Spontaneous process is a very important concept in chemical thermodynamics, but its definitions are quite different in different textbooks. Besides, the explanations on the deciding of spontaneous process are unclear. Therefore, difficulties arise in the process of teaching. In this respect, discussions are made on the merits and demerits of different definitions with analysis made on the reasons for the discrepancies of definitions. Moreover, the conditions for deciding according to entropy as deciding according to spontaneous process are discussed. |
