摘 要: 用系统的内能和总能量两个概念解释并消除了热力学和统计物理中电磁介质在外场中热力学基本方程的差别。用通用特征函数导出当自变量为T,P,M时的特征函数为U,即吉布斯函数G。当系统自变量为T,P,H时的特征函数为U。从而可把热力学和统计物理中对该系统的热力学讨论统一起来。 The concepts of internal energy and total energy are adopted to explain and to eliminate the difference in the basic equations of the dielectric and magnetic material between thermodynamics and statistics. According to the general characteristic function, when the independent varibles are T, P and M, is ^((1.0))U, i. e. Gibbs function. But the characteristic function, when independent varibles are T, P and H, is ^((2.1.0))U. So we can unify thermodynamic discussion of the system in statistics with that in thermodynamics.
