作为这些沉淀离子的补充，来自阳极的金属被溶解并进入溶液平衡离子势能。

As a replenishment for these deposited ions, the metal from the anode is dissolved and goes into the solution and balances the ionic potential.

由于这些带负电的粒子(称离子)使带正电的树脂保持在溶液中，它们有时被叫做平衡离子。

Since these negatively-charged particles (called ions) help keep the positively-charged resin in solution, they are sometimes referred to as counterions.

一种情况是正负离子平衡问题，或比率问题。

One thing is the balance or ratio between positive and negative ions.

And there is this separation which is a balance of attractive forces because the chloride is net negative and the sodium is net positive, but both of them, regardless of net charge, have electrons.

这里有一个平衡,引力的平衡,由于氯离子带有负的净电荷,钠离子带有正的净电荷，但是它们两个，没有考虑净电荷，电子。

The balance of sodium movement relative to potassium movement changes because there's this resting movement of all these molecules anyway, but that balance changes dramatically when these ion - when these gated ion channels open.

钠钾各自运动始终保持动态的平衡,因为尽管在静息状态,所有这些离子也在运动,但是平衡的剧烈变化,只发生在这些门控离子通道打开的时侯
