摘　　要：针对现有仪器分析教材中有关电位分析法中电池电动势计算方法的论述上的概念性模糊、公式间相互矛盾等展开了较深入的讨论，并做了相应的实验验证．指出电位分析法中真正要知道的是２支电极之间的电位差及其与被测离子活度之间的关系而非电池电动势。The definition of the electro motive force of voltammetry in most current textbooks is vague.This article disscussed the problems related.Four experiments have been done to prove our view pint.It could be concluded that it is important to know potential difference of the two electrods other than the electro motive force of the cell in Voltammetry and that the potential difference can be claulated by the equation: E P=Φ I-Φ R ( P :Potential diference; I :Indicator; R :Refrence.)
