Then updraft wind currents carry the light, positively charged ice crystals up to the top of the cloud.

然后上升气流将轻盈的、带正电荷的冰晶带到云的顶部。

Concentrations of positively charged particles develop at the top and bottom of the cloud, but the middle region becomes negatively charged.

带正电荷的粒子集中在云团的顶部和底部，但中间区域形成的是带负电荷的粒子。

When the negatively and positively charged streams meet, a complete channel connecting the cloud and the ground is formed.

当带负电和带正电的粒子流相遇时，就会形成一条连接云层和地面的完整通道。

So, we know now that we have charged particles. Are these negatively or positively charged based on this evidence?

弯曲的角度,现在我们知道,阴极射线是带电粒子,但从这个实验？

So, by the same logic, that means that all of our positively charged ions are, in fact, going to be smaller in terms of radius, compared to their neutral parents.

那么，按照相同的逻辑，我们所有的正离子，事实上，它们的半径都会缩小，与它们的中性母体相比。

According to this theory, the atoms consist of a positively charged nucleus surrounded by a stream of electrons kept together by attractive forces from the nucleus.

根据这个理论，原子由一个带正电荷的核组成,由于来自核的吸引力,电子流围绕在核的周围。
