But now,if I integrate the charge density over the entire region, then what I will get is actually the total amount of electric charge inside the region.
如果将电荷密度对整个区域做积分，将得到,在区域内的电量总和。
A proton contains three charged quarks bound by the strong force and its radius is defined as the distance at which the charge density drops below a certain value.
一个质子由三个带电的夸克通过强相互作用力结合而形成，它的半径是由电荷密度降到某一确定值的距离来确定的。

So for example, that might have a formal charge of negative 1, because to some extent it has gained that much electron density that it now has a formal charge that's negative.
比如，可能它的形式电荷为负一，因为在一定程度上它得到了这么多的共用电子密度,那么它现在就有了负的形式电荷。
