摘　　要：改进了林文如酸碱双点电位滴定方法，导出了不作近似的计算公式，并对该方法准确度进行了探讨。用于鱼油酸价测定，其相对误差皆小于１％Lin Wenru method was improved.In this paper,a nonapproximate calculation formulae of the acidbase titration with doublepoint potentiometric method has been described and the factors which affect the accuracy of measurement results has been discussed.The experiment showed that the titration relative error for acid value of fish oil was less than 1%.
