二元系相图中的数学方法

本文介绍绘制二元系各类相图的数学方法。它是把确定相图中分溶曲线的问题,转化为通过确定平面动力系统来确定初值的一条轨线的问题。这样,可以用计算机来绘制二元系的相图。同时也为从相图来研究二端元的活度和活度系数提供了一个新的途径。

MATHEMATICAL METHOD IN PHASE DIAGRAMS OF BINARY SYSTEM

This paper introduces the Mathematical method for drawing the phase diagrams of binary system, which transforms the problem of the dissove curve in determining phase diagrams into the problem to determining a initial value trajectory through determination of the planar dynamical system.This method can draw diagram using computer.This paper deals mainly with the dynamical system and the initial value of the dissove cure of phase diagrams of binary systems of the eutectic, the incogruent melting, the complete solid solution.It'r also a new method to studyying activity from the phase diagrams.
