利用ｐＨ滴定法测定多元弱酸逐级条件稳定常数ｌｏｇｋ＇＿ｉ的通用公式，由ＭｏｎｔｅＣａｒｌｏ法确定各ｌｏｇｋ＇＿ｉ初值，Ｈｏｏｋｅ－Ｊｅｅｖｅｓ法进行精解，对实验点进行了非线性拟合。计算结果表明，本法实验简便，数值运算效率高，收敛快。
The general formula for determining the logk’_i stability constant of stepwise condition of multivariate weak acid was determined by pH titration. The initial values of logk’_i were determined by Monte Carlo method. The Hooke-Jeeves method was used for the solution. The experimental points were nonlinearly fitted. The calculation results show that the method is simple and convenient, the numerical calculation efficiency is high, and convergence is fast.
