摘要：对多元酸浓度的计算方法作以改进，采用单纯形优化法优化稳定常数，所得结果与实际情况符合良好。通过对一元酸、二元酸（混合酸）、三元酸等体系的计算结果分析表明，单纯形优化法可以获得各种酸浓度相对误差小于１％的满意结果。
According to experimental data, when the concentrations of polybasic acids were obtained,the conditional stability constants were calculated directly. And they were optimized by the modified simplex method. These results agree with the actual results.On the basis of the calculating results of various polybasic acid systems,the relative error of the concentration,which were obtained using the modified simplex method, was less than one percent.
