讨论如何由无空间电荷存在的场求空间电荷作用下电子注的包迹。

Method of calculations for electron beam comtours including the effect of space charge was derived from the field free of space charge.

这些胶囊按照像素排列，电荷会作用于每个像素点上，将白色或者黑色的粒子拉到胶囊的顶部（同时，那些相反的颜色会被排斥到底部）。

The capsules are arranged as pixels and electric charges applied to each pixel pull either the black or the white particles towards the top of the capsule (and the opposite colour to the bottom).

When the charge is applied, if the upper plate is negative, we would expect that the negative droplet would be repelled at a rate exceeding the gravitational fall.

当电荷起作用时，如果上边的板子是负电的，我们可以期待负电的液滴会,超过重力下降速度的速度被排斥。

And let's say our second electron now is really far away, such that it's actually not going to shield any of the nuclear charge at all from that first electron.

距离原子核非常非常近,我们说第二个电子处于非常远的位置,这样它不会对第一个电子,感受到的来自原子核的电荷量有任何屏蔽作用,我们最后要说的是。
