过程方向的热力学判据及其在有功参与过程中的应用

Thermodynamic criteria and their application in work involving process

将新的自发过程定义与热力学第二定律相结合,推导出了更加方便、适用的过程方向的热力学判据,其中包括有功参与的过程方向的热力学判据,解决了长期困扰物理化学工作者的一个理论问题,即有功参与的过程方向无热力学判据的问题。详细说明了该判据在电化学、表面化学及光化学等特殊物理化学过程中的应用。

Based on the second law of thermodynamics and the new definition of a spontaneous process,the more convenient and applicable thermodynamic criteria that include the criteria for the process involving work are deduced.The applications of the criteria in electrochemical process,surface process and photochemical process are illustrated in detail.
