1.
A positive electric charge.
正电正电荷，阳电荷
2.
Electrical positives attract electrical negatives.
正电荷吸引负电荷。
3.
An electron with a negative charge, as contrasted with a positron.
电子带有负电荷，与正电荷相反的电子
4.
Electrons are negatively charged with electricity; protons are positively charged
电子带有负电荷，质子带有正电荷。
5.
Electrons are negatively charged with electricity,protons are positively charged.
电子是带负电荷的,质子是带正电荷的。
6.
Neutron has no charge, either positive or negative.
中子既不带正电荷，也不带负电荷。
7.
Two negative charges repel each other, and so do two positive charges.
两个负电荷相斥，每个正电荷也是如此。
8.
Two negative charges repel each other , and so do two positive charges .
两个负电荷相斥，两个正电荷也是如此。
9.
The fur must have a positive charge.
毛皮必定带有正电荷。
10.
Similarly, either an addition of positive charge or a removal of negative charge will result in an excess positive charge.
加入正电荷或移出负电荷，都将同样地导致过剩的正电荷。
11.
If a body is nonelectrified, the positive charges balance with negative ones.
如果一个物体不带电，它的正电荷与负电荷相等。
12.
We believe that there are electrical charges of two kinds, called positive and negative, in each atom .
我们确认，每一个原子具有两种电荷：正电荷与负电荷。
13.
As mentioned above, an object has positive charge when it has lost electrons.
如上所述，物体失去电子时带正电荷。
14.
This influx of positive charges reduces the potential.
这种正电荷的内流导致电位减
15.
"The potential energy of a positive charge increases when it moves against an electric field, and decreases when it moves with the field. Electric potential can be thought of as potential energy per unit charge. "
正电荷逆电场方向运动时,位能减少。电势可比作每单位电荷的位能。
16.
Some of these positive charges are then satisfied by electrons blowing in from wire B.
然后，这些正电荷中的一些电荷由从导线B流入的电子得到补偿。
17.
Qualitatively, the equations mean this: Electric fields point out from positive charges and into negative charges, and magnetic fields curl around currents (moving charges).
定性地看，这个方程组意味着：电场是由正电荷指向负电荷，磁场围绕着电流即移动的电荷。
18.
As is known to all, like charges repel while unlike charge attract.
正如大家所知道的，同种电荷相斥，异种电荷相吸。
