三元四元简单水盐体系相图的自动分析及绘制

Automatic analysis and phase diagram drawing of simple ternary and quaternary water-salt system

通过分析水盐体系中自由度及相图中点与线的关系,研究了能够自动分析相图中点与线的算法.此算法能利用相图数据点上的液相离子组成和平衡固相分析出点的类型及点之间的连线关系.并基于此算法开发了相图绘制程序,此程序能够自动分析并绘制三元和四元简单体系的等温相图.

By analyzing the degrees of freedom and relationship between points and curves in water-salt phase diagram, the arithmetic was researched to analysis the phase diagram. Using the data of phase equili- brates and equilibrium solid phase, the type of point and relationship of points can be obtained. The phase diagram drawing program was developed based on this arithmetic,it can automatic analysis phase equilibrate data and draw phase diagrams of simple ternary and quaternary phase system.
