麦氏恒等式与麦氏关系式证明与应用

The Prove and Application of MaxweIl's Formula and Maxwell's Relation

从热力学基本方程出发,利用勒让德变换和全微分性质证明了热力学中麦氏关系式和麦氏恒等式;从麦氏关系式出发导出熵和物态方程,应用麦氏恒等式证明定压热容量和定容热容量之差的关系。

From thermodynamic basic formula,The Maxwell＇s relation and Maxwell＇s formula can be made by using Legendre transformation and the differential properties.From Maxwell＇s formula,the entropy and equation of state is derived;the constant pressure heat capacity and constant volume heat capacity difference can be gotten by using Maxwell＇s relation.
