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 one another; thirdly,φ i is compared with the chemical potentials φ of other components in this crossing point by chemical potentials minimization.

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，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。

Individuals crossing exclusively within the same population produce more progeny than those crossing in both directions and thereby use up some of their gametes for the production of inviable hybrids.

完全在同一种群内进行杂交的个体比以两个方向进行杂交的个体繁殖后代要多，因此为了产生无生机的杂种，就要消耗掉一些配子。
