Most of the time, there's about the same number of positive and negative particles in any object you can think of … like my balloon … or my shirt.

大多数时候，在你能想到的任何物体中， 正粒子和负粒子的数量大致相同… … 比如我的气球… … 或我的衬衫。

And most of our atmosphere is made up of gas molecules that don’t have an electric charge – they all have a balanced number of positive and negative particles.

我们的大部分大气是由不带电荷的气体分子组成的——它们都有数量均衡的正粒子和负粒子。

Now the inside of the shell has a net negative charge due to the attraction of the central positive particle leaving the outer shell with a net positive charge.

内壳现在有一个总的负电荷 它是由中心正粒子的吸引力引起的。

And when there's an imbalance of positive and negative particles in things -- like when the balloon has more negative particles than positive ones -- it's said to create static electricity.

当事物中的正负粒子不平衡时——比如当气球的负粒子多于正粒子时——据说会产生静电。
