【摘要】 本文从平衡判据的普遍规律——克劳修斯不等式出发,按照不同的过程条件,分别讨论了熵判据、亥氏函数和吉氏函数判据以及相变化和化学变化的可逆性判据。同时指出了这些平衡判据所包含的物理意义及它们间的一些内在联系。更多还原

【Abstract】 From the point of the general criterion of equilibrium——Clausius inequality,we discussed the various expressions of criteria in terms of the entropy,the Helmholtz energy,the Gibbus energy and the reversibility of physical and chemical changes in different processes with the specified constraint conditions.Furthermore,we interpreted the physical significance of these criteria and elucidated the relationships among them.更多还原
