普遍适用于两相平衡体系的相关式

Universal Relationship Equation in Two Phases Equilibrium System

本文提出了一个能普遍适用于两相平衡体系的基本关系式，讨论了该式与其它相关方程式、定律的内在联系，并对相图中的恒沸点。

In this paper, a universal basic relationship equation in two phases equilibrium system has been proposed. The internal connection between this formula and other relative equations or laws have been discussed. The degree of freedom on the constant boiling point and the critical point in phase diagram has also been explained.
