同时，每个液滴上的极化朝着相反电荷的方向积累。

At the same time, the poles of each drop were acquiring opposite electric charges.

不使我们粘到任何相反电荷物体上面去的原因是这些力必须排列合适才能起作用。

What prevents us from sticking to anything with an opposite charge is that all these forces have to be properly aligned before you can see them at work.

youdao

在胶体中加入一些能够吸附在它上面的带相反电荷的分子，有时可以中和其电荷。

The charge on a colloid can sometimes be neutralized by addition of molecules of opposite charge which have the ability to absorb onto the colloid.

youdao

These gas ions, if you take gas ions, these gas ions, if you take gas ions, gas ions of opposite charge will necessarily agglomerate without limit.

这些气态离子，如果你得到气态离子的话，如果你得到这些气态离子，具有相反电荷的气态离子,将必然会无限地聚集。
