讨论了在热力学中容易混淆的混乱程度、剧烈程度。

The concepts of degree of anarchy,severe degree,and changes of entropy are often obscured by beginners.This article gives some examples to make these concepts clear.It considers the severe degree be related to the average of kinetic energy of molecules.The degree of anarchy,however,is in erlation with the order in the phase space.A change of entropy is a mesurement of the changes of the order of the system.
