摘    要：介绍了新开发的优势图计算机绘制系统,提出了绘制优势区图的一种新算法——主元素活度项法,说明了绘制含一种金属的三元系及含两种金属的四元系的优势区图绘制的算法原理,解决了四元系中双金属化合物的归属问题.算法简易,效率高,符合热力学原理.系统采用C⁺⁺语言,基于Windows3.X/Win95平台编制了优势图绘制系统的应用程序.该系统具有使用简单,维护方便,界面友好,输入少量的信息即可得到完整的优势区图.

Abstract: This paper briefly describes a newly-developed computer plotting system of predominance area diagrams. A new method for plotting metal predominance area diagrams, activity term method of base element, is proposed in this paper. In the proposed method, the principle of one-metal and two-metal predominance area diagrams is demonstrated and the problem of two-metal complex species is solved. The algorithm is easy, efficient and conforms to the thermodynamic law. The system is programmed with C⁺⁺ language based on the Windows 3.X/Win95 operation system.The soft system presented is simple and friendly to the user.
