摘　　要：不少物理化学教材中,把总熵作为体系自发过程方向和限度的判据,然而,总熵判据不完全正确,是片面的,产生片面性的原因是扩大了研究的对象。要应用总熵判据,必须要加上一个环境不向体系做功的限制条件。In several reference books, total entropy criterion was used to determine the direction and limitation of the process. However, there is one--sided and improper influence as the application range is enlarged. A restrictive condition, surroundings does not apply work to system, it should be added when using entropy criterion.
