理想气体一般准静态过程吸、放热量的讨论

Endotheorm and Exotherm of the ldeal Gas in an Ordinary Qnasi-Stationary State

本文讨论了一段吸热而另一段放热的一般准静态过程,从理论上证明了转变点就是过程曲线与绝热线相切时的切点,找到了判别过程转变点的依据,导出了计算转变点Pc、Vc值的两种方法,最后还阐述了如何分段计算热量。

This paper discusses the quasi-static process in which one region heat is resorbed and the other heat is released. From theory it proves that the point of variation is the cut point when the curve of process cuts the line of adiabatic. It finds the base of discrimination of the point of variation. Two methods are found of calculating the values of the points of variation PC, vc. Finally it describes how to Calculate the quantity of heat by means of dividing reaions.
