热力学第二定律的信息论表示式及其应用

A Representative of Information Theory of Second Law of Thermodynamics and Its Some Applications

本文运用信息量负熵原理给出了热力学第二定律的信息论表示式——孤立系的信息量减少原理.把热力学观点和信息论观点结合起来进一步阐述了热力学第二定律的本质.通过对单原子理想气体的扩散问题的简单讨论,结合Shanonn的信息量公式,定量地说明了热力学第二定律的熵增加原理和信息量减少原理两种表述的一致性.本文还应用信息量减少原理为光速c作为极限速率提供了一种新的论证方法.

This paper gives representative of informa-tion theory of second law of thermodynamics with the use of neg-entropy principle of information.This representative is used todiscuss the problem of gaseus diffusion and provide a new me-thod for proving the light speed c as the limit speed.
