PVT系统的热力学性质

THE THERMODYNAMIC CHARACTER OF PVT SYSTEM

给出了ＰＶＴ系统的物态方程和热力学微分方程，并通过对描述ＰＶＴ系统的四个热力学量Ｐ、Ｖ、Ｔ、Ｓ的偏导数的讨论，确定了为ＰＶＴ系统的三个基本热力学偏导数。

This paper gives out PVT system's Equation of state and Equation of differential in thermodynamics.Discussing the derivative of P. V. T. S, we define for system'sbasic derivative of thermodynamics.
