If there is no charge on the plate, these droplets will simply fall under gravity.
如果在板子上没有电荷,这些液滴就只会由于重力掉下。
And then there is this third species, the neutron, which has no charge.
这是第三种了,中子,不带电。
There's no charge to students.
对学生是免费的
So if we add them all up, there should be no net charge on the molecule, if the molecule is neutral.
因此如果我们把它们都加起来,这个分子上应该没有净电荷,如果这个分子是中性的话。
The bartender says, "for you, no charge." OK.
酒保说,对你,不要钱。
Neutron has no charge.
中子不带电。
We will provide tutorial assistance at no charge.
我们将无偿提供个别辅导。
Now the last thing is that because the neutron has no net charge, we can change neutron number.
现在,最后一件事是,因为中子没有净电子,我们可以改变中子数。
We said that that second electron was so far out of the picture, that it had absolutely no affect on what the charge was felt by that first electron.
我们说第二个电子远离这张图片,这样它就彻底的对,第一个电子感觉到的电荷没有影响了,所以。
So now that means if this is where the center of positive excess charge lies and on top of it is the center there is no displacement of the charge so there is no net dipole.
所以现在我们说,如果正电荷中心,就位于,那么还是在这里负电荷中心也在这里,所以没有空间偶极。
