摘　　要：针对板式电位差计测量电阻的实验装置,以干电池为研究对象,用补偿法测量实验数据,引入SPSS的曲线估计功能,得到并验证出长度和标准电阻的复合量与长度量的定标曲线,由此标定出待测干电池的内阻。用置信概率为95的不确定度,对实验结果进行分析和评价,最终得到更为直观的、可靠的实验结果。The paper applies plate potentiometer and compensation method to measure inner resistance of dry battery. In addition, we obtain the calibration curve between the compound quantity of length and standard and length. The paper testifies the calibration curve between the compound quantity of length and standard and length. Therefore, the paper gets the inner resistance of dry battery. We evaluate the experiment data and result with the uncertainty confidence probability of 95% . It has shown that we gain reasonable experiment result.
