总熵判据与克劳修斯不等式

NET GAIN OF ENTROPY AND INEGUALTG OF CLAUSIUS

热力学第二定律的墓本课题即是判别过程的方向性,利用嫡变可以判卿万,.体系中过程的方向,但不适用于一般体系。为了扩大利用嫡判据的范围,往往将体7几手;环境作为一大体系(弧立体系)考虑。

The net of entropy is usod to judge the spontaneity of tho total change of system and reservoir, and it can not judgo the spontaneity of the change of system. The net of entropy and tho ineguality are the sano in essence.Both of them mag be used to judge tho reversibility and tho spontanoity of process When they are used to judge the spoutanoity of process, the change of system does not expend the net work.If they are used tojudge the reverolbility of process, the limited condition about the net work is unnecessary.
