论孤立系统的熵与开放系统的熵

Study on Entropy in Isolated System and Open System

阐述把热力学第二定律滥用于整个宇宙的错误论点,论述孤立系统的熵变关系与开放系统熵变的区别与联系,在此基础上重点叙述开放系统熵变的问题.论文中针对生物系统的开放性,结合熵理论解释了开放系统的负熵论观点.并引出信息熵,叙述了信息熵与负熵的等价性.

On the basis of discussion the distinction and relation of entropy in isolated system and in open system, this paper mainly states the entropy change in open system. Aiming to the openness of the biological system, the author, combining the entropy theory, analyses the negative entropy theory in open system. The author also introduces the information entropy and states the equivalence between information entropy and negative entropy.
