| 摘 要： | 本文阐述封闭体系中的熵产生原理.据此原理说明封闭体系经历一个任意过程,体系的熵变等于熵流dSe和熵产生dSi之和.体系若经历一个不可逆过程必定产生熵,经历一可逆过程,熵产生等于零.把熵产生原理应用于封闭体系中的各种过程,可以判断过程的性质,它较Clau-sius不等式和孤立体系中的熵判据更为简便.

| Abstract: | :The principle of entropy production for a closed system is derived from the Clausius inequality in this paper. It shows that when a closed system has changed a change of entropy of system equals the sum of flow of entropy and entropy production. Irreversible processes generate entropy. The principle of entropy production is easier to be understand and more convenient to be used than the Clausius inequality. |
