系统研究了化学计量学方法在滴定分析中的应用，将多元线性回归与ｐＨ络合滴定方法相结合同时测定稳定常数极为接近的金属离子钴和镍，获得良好结果，同时还探讨了该法原理，回归方程及最优条件．
The application of chemometric method in titration analysis was systematically studied. The combination of multiple linear regression and pH complexometric titration was applied to determine the cobalt and nickel metal ions with very closestate constants, and good results were obtained. The principle of this method was also discussed , Regression equation and optimal conditions.
