摘要
提出了一种新的绘制φ—pH 图的方法, 即先求出所有的单变线方程, 再选取某一种组分Mi 为主组分, 把含有该组分的所有单变线方程两两求解, 求出交点( φi ,pHi) , 然后用化学势约束原理法, 将主组分同其它组分在该点的化学势作比较, 若前者的化学势小于后者, 则该点为所求的三相点。把生成该三相点的所有组分用数组标记, 若任意两个三相点有两种组分相同, 便可连成线。
A new method of drawing φ —pH diagram has been proposed. Firstly, all of univariant line equations are attained; secondly, a crossing point ( φ i , pH i ) is got by solving univariant line equations including a main component(M i ) one another; thirdly, φ i is compared with the chemical potentials φ of other components in this crossing point by chemical potentials minimization. If φ i < φ , then the crossing point is the point of three phase, components in the point of three phase are labeled in an array; if two components of two points of three phase are same, then the two points of three phase are lined safely.
