Even in fair weather, a very small electric field is present in Earth's atmosphere. This field can charge airborne particles and the edges of clouds, Harrison said.

哈里森说，即使很好的天气情况下，地球大气层的电场依然存在。电场可以使空气中传播的粒子以及云端边缘带电。

And the charges in the plates are what causes the electric field between the plates. That is how you can get the relation between voltage and charge in these guys.

板材上的电荷，生成了薄片间的电场，这就是得到电势与电荷之间关系的方法。

Just to give you formulas, the force caused by the electric field is the charge times the electric field.

先给出一个公式，电场生成的力，等于电荷与电场之积。

The method works because the electrical field polarises the electric charge on water molecules in the air around the icy tip and then draws them in electrostatically.

My proposal with this fellowship will use the novel method of applying an electric field gradient instead of chemical substitution to induce charge carriers in large gap insulators, and thereby create new superconductors.

Mass spectrometry works by evaporating molecules, giving them an electric charge, and then applying an electric field to them and accelerating them through a vacuum chamber to a detector.
