Use the way with peak data taken by stepped processing to get more exact and scientific results during data processing for evaluating electroncharge and charge mass ratio.
在电子电量与荷质比测定实验的数据处理过程中，采用分步处理取峰值的方法，使结果更准确、更科。

This found that if the reverse idea of the electroncharge-mass ratio as a known quantity, it can re-theoretical derivation, and thus obtain the value of the vacuum in the speed of light.
