泥浆沥清过程熵增物理机制研究

A Study on the Entropy Increase Physical Mechanism of Mud Sink to Settle Course

深入探索了泥浆沥清过程的物理机制,然后从理论上证明其过程满足热力学第二定律,最后发现:对于非孤立系统,可以把与系统有相互作用的那部分环境划出来与系统一起构成一个“新孤系”.其熵变有两种机制:一是系统与环境之间的热交换,热交换伴随熵交换,它可以使系统的熵增加,也可以使系统的熵减少;另一种机制是系统内部的不可逆过程,它只能使系统的熵增加.其总体情况是:在系统与环境的交界存在熵流,在系统内部存在不断往外“冒熵”的熵产生源泉——不可逆过程.

This paper discussed deeply the physical mechanism of mud sink to sere, then theoretically proved its course satisfy thermodynamic second law. Finally,The author drew a conclusion as follow： to the system which is isolated system, we can strike the part of environment interact with system out to form a ＂new isolated system＂ with system., it＇s entropy change have two mechanisms： one is the hot exchange between system and environment, which accompany with entropy exchange, it can make systematic and entropy increase, and make systematic and entropy decrease, too; the other kind of mechanism is systematic built - in not reversible course it can only make systematic and entropy increase. Its overall condition is that the boundary of system and environment exists entropy flow, systematic intemal existence the source that go continuously outside with ＂emit entropy＂ ——not reversible course.
