图线法判断任意准静态过程吸、放热问题

The Heat Exchange in Quasi-Stationary Process by Using Diagram Analysis

为了更直观地判断准静态过程中系统的吸、放热问题，可以通过不同的物态参全国（如Ｐ－Ｖ图、Ｐ－Ｔ图、Ｔ－Ｖ图、Ｔ－Ｓ图）来分析。本文试图对此问题进行一些讨论。

For directiy analying the heat exchange in quasi-stationary process,we may use dis-tinct diagmin of pammeter for analysing(e.g P-V、P-T、T-K、T-S diagram),this acticletries to discuss thase problems.
