By use of magnetic balance which is general physical experiment instrument, a simple and new method of measuring the charge-massratio of electron mass developed.
使用常用物理实验仪器磁天平，开发出用于近代物理实验测量电子荷质比的简易新方法。

This found that if the reverse idea of the electroncharge-massratio as a known quantity, it can re-theoretical derivation, and thus obtain the value of the vacuum in the speed of light.
笔者发现，如果进行逆向构思，把电子的荷质比作为已知量时，可重新进行理论推导从而得到真空中的光速值。

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 massratio.
