摘　　要：为使学生理解补偿法对减小实验系统误差的作用,介绍了补偿法测电流的原理,分析了其不确定度,由结果可知补偿法测电流可显著减小系统误差。学生通过实验对补偿法有了具体认识,并清楚的看到补偿法能减小实验系统误差。In order to make the students understand the compensation method to reduce the experimental error function, a method of measuring current by compensation is proposed, the analysis of uncertainty is given and the result shows the measurement of current by compensation method can distinctively reduce the systematic error. Students through the experiment with the specific understanding of the compensation method, and clearly see the compensation method can decrease the error in the experimental system.
