正电和负电

1

摩擦也有可能分离正电和负电而产生很强的静电场。

Friction can also separate positive and negative charges and generate strong static electric fields .

电子墨水的显示技术是依靠无数的带正电和带负电的微胶囊充电。

Ink : This display tech relies on millions of positively and negatively charged microcapsules .

但是还有别的问题，因为我现在得到了带正电的东西和带负电的东西。

But there 's more because now I 've got pluses and minuses .

如果我把带正电的东西和带负电的东西都放在，一个气相中，会是什么样呢？

So , what happens if I put pluses and minuses in a gas phase ?
