功变热过程不可逆性的统计分析

A statistical analysis of the process converting work to heat

功变热过程是系统从有序运动向无序运动的转化 .本文在分析功变热过程的基础上 ,引入了功变热过程的简化模型 ,利用经典玻尔兹曼分布计算了一定量气体[1] 从有序运动向无序运动转化中的熵变 .结果表明 ,此过程系统的熵增加 .

The conversion of work to heat is the process from order to chaos.The process converting work to heat is analysed introducing a model.The entropy change in the process is calculated by classical Boltzmann distribution.In result,the entropy increased.
