在第一钳口线之前和之后设有至少一个用于偏转纤维须条的机械机构。

At least a mechanical mechanism for deflecting the fiber fringings is equipped before and after a first Jew line.

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。
