摘　　要：以非等精度法用电势差计测量电池的电动势和内阻 ,通过这一尝试 ,说明非等精度测量是一种误差小、准确度高、能使学生实验操作能力得到充分训练的好方法 .Applying the method of unequal precision measurement, we have tried to measure the emf and the internal resistance of a cell with potentiometer. It shows that the method has the advantage of higher precision and is good for developing the students′ ability of experiment operation.
