将所有溶液态物质作为一个整体， 绘制了 Ｍ Ｈ２ Ｏ 体系综合平衡电位ｐ Ｈ 图。任何非溶液相物质 Ｘｊ 优势区的边界线可简单地通过比较与 Ｘｊ 呈平衡的所有溶液态物质的总浓度Σ Ｃｉ 和任一给定总浓度［ Ｍ］ Ｔ 的大小来确定。当体系中所有固相和气相优势区的边界线确定之后， 剩余的区域就是溶液相物质的优势区。在微机上自动绘制了 Ｚｎ Ｈ２ Ｏ、 Ｓ Ｈ２ Ｏ 和 Ｃｕ Ｈ２ Ｏ 体系的电位ｐ Ｈ 图， 并对［ Ｃｕ］ Ｔ＝ １０ － ８ ｍｏｌ·ｌ－ １ 时文献报道的 Ｃｕ Ｈ２ Ｏ 体系电位ｐ Ｈ 图做了更正。本文报道的方法简单， 运行时间短， 能自动生成各物质的稳定相区并自动消除不稳定相区。 The solution of all the material as a whole, drawn M  H 2 O system integrated equilibrium potential  p H map. The boundary of any Xj-dominant region of the non-solution phase material can be simply determined by comparing the total concentration Σ Ci of any solution-state material that is in equilibrium with Xj and the magnitude of any given total concentration [M] T. When the boundaries between all the solid-phase and vapor-phase dominant regions in the system are determined, the remaining region is the dominant region of the solution-phase material. The potentials  p H diagram of ZnH 2 O, SH 2 O and CuH 2 O systems were automatically plotted on the microcomputer, and the CuH 2 content reported in the literature [Cu] T = 10 -8 mol·L -1 O system potential  p H map was corrected. The method reported in this paper is simple and has short running time. It can automatically generate the stable phase of each substance and automatically eliminate the unstable phase.
