不同成分的水混合是一种常见现象。将电荷中性方程引入水中物种平衡分布计算方程中，即可计算出混合水的pH值。本文采用黄金分割法对所得方程组进行求解。为了验证计算方法，对三组混合水进行了室内实验。结果表明，计算值与实测值吻合较好。
Mixing of waters with different compositions is a common phenomenon. The pH of mixed water can be calculated by introducing charge neutrality equation into the equations for equilibrium distribution calculation of species in water. In this paper, the equations thus obtained were solved by golden section method. To verify the calculation method, laboratory experiments were done for three sets of mixing water. The results showed the calculated pH values are in good agreement with measured ones.
