An atom's nucleus has a positive charge.

核带正电荷。

The fundamental charges are a positive charge and a negative charge.

基本电荷正电荷和负电荷。

At the center of an atom is its nucleus which has a positive electric charge.

的中心它的核，它带有正电荷。

Protons have a positive electric charge, electrons a negative charge, and neutrons are neutral.

质带正电荷，电带负电荷，中则中性的。

By applying a positive charge to the control electrode, it would permit the flow of electrons as before.

Bees, on the other hand, develop a slight positive charge just by flying through the air.

另一边，蜜蜂通过在空中飞翔获得微弱的正电荷。

The short and sweet of it is that the waste molecules lose electrons and become more positively charged.

简单来说，废物分失去电，带更多正电荷。

A positron for example is just like an electron but it has positive charge.

比如一个正电，就一个电，带有一个单位正电荷。

Electrons whiz around the nucleus, their negative charge attracted by the protons' positive charge.

电绕着核旋转，它们的负电荷会被质的正电荷所吸引。

Atoms that big need electrons to help stabilize all that positive charge packed together in the nucleus.

如此大的需要电来帮助稳定核中聚集在一起的所有正电荷。

Sometimes, the ground acts like an accumulator for the positive charges so that the lightning strikes direct into the ground.

有时，地面就像一个为正电荷的蓄电池，因此闪电直接击中地面。

And it's the ions with a positive charge of 1 or 2 that really cause problems.

正电荷为 1 或 2 的离才真正的问题所在。

Positrons are essentially electrons with positive charge.

心电图描记明确显示了除极波在每次心跳中怎样运动的；除极波一种正电荷的波。

So this is a negative charge and then you have positive charges in the center.

所以这一个负电荷，然后你在中心有正电荷。

These, despite being mutually repulsive because they are positively charged, are held together by a phenomenon called the strong nuclear force.

虽然质之间因带正电荷而相互排斥，被强核聚集在一起。

Sodium lost an electron, so it ends up with a positive formal charge, like that.

钠失去了一个电，所以它最终带有正电荷，就像那样。
