We know that charge is equal to the integral of current times the time. And he knows the current, he knows how much time and then he weighs this.

我们知道电量等于电流,对时间的积分，他知道电流，他也知道时间，然后他测量这个。

So, how could he know that the charge on the two particles was equal?

就是这两种粒子,电荷量是相等的？

The first, which I just stated, is that the deflection of that negative particle was just far and away more extreme, much, much larger than that of the positive particle. The other assumption that he made here is that the charge on the two particles was equal.

为了这么做，他又做了更多的观察,首先，像我之前已经说了，测到的负电粒子,偏转要远远,大于正电粒子,另外一个他做了一个假设。
