Abstract: 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.

Key words: Millikan oil-drop experiment, elementary electrical charge, least square method
