理想气体任意准静态过程中两个状态间的熵变

The Entropy Change Between two States of an Ideal Gas for an Arbitrary Quasi-Static Process

本文给出计算理想气体的任意准静态过程中两个状态间熵变的公式和判断熵变符号的判据.并将此公式与判据应用于四种等值准静态过程和实例,得出了一些重要的结果.

In this paper the authors give the formulas for Calculating the entropy change of an ideal gas between two states of an arbitrary quasistatic process and the criterions to determine the plus minus signs of the entropy change. Using them to four quasi-static processes and two examples, some important results are gviven.
