摘　　要：从元电荷反证法出发,通过对其误差项进行分析、讨论,提出了一种利用对数求解元电荷e值的实验数据处理新方法.通过对大量实验数据样本的计算结果表明,这种方法能有效地减小数据处理的误差,提高元电荷e值的测量精度,与元电荷反证法相比数据处理精度约提高一个数量级.Starting from the elementary charge reductio ad absurdum, through the analysis of its errors and discussing, a new data processing method for solving e values of the elementary charge using the logarithmic is proposed. The calculation results for a large number of experimental data samples show that this method can effectively reduce errors in data processing, and improve the measurement precision for e values of the elementary charge, data processing accuracy improved by about one order of magnitude compared with the elementary charge reductio ad absurdum.
