| 摘 要： | 在目前所流行的任何一本普通物理教材中,对公式W=—PdV都未作过推导。只是在某些热力学专著中作一些说明,但也从未作过严格的推导。本文较严格地导出了计算准静态过程功的公式,并讨论了该公式的适应条件,指出该公式只对无摩擦的准静态过程,以及等压或等容的非静态过程适用。澄清了一些易于误解的问题。

| Abstract: | In any current general physics textbooks there is no deduction from fordula dW=-PdV, only some speculations in some thermodynamics literature. No rigorous deduction has ever been manifested. In this paper, a formula calcylating the work of quasi-state process is discribed in a rigorous way. Posing condiction in which the formula can be used is discussed. It is proved that it is only useful for zero-friction quasl-state process, non-quiet isometic or isobaric process. Finally, Some problems caused by confusion are solved. |
