And I think people would start looking to see, well, maybe other dimensionless ratios like the ratio of the mass of the electron to the mass of the proton are changing.

而且我认为人们也会开始考虑，像电子的质量对质子的质量的比值，也许其他无量纲的常数也在发生变化。

The energy equipartition time is longer than the interparticle collision time by the mass ratio of proton and electron.

由于质子与电子的质量比很大，能量平衡时间比粒子间碰撞时间长。

Use the way with peak data taken by stepped processing to get more exact and scientific results during data processing for evaluating electron charge 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。
