它们的活动被离子间的引力所制约。

Their action is impeded by interionic attraction.

这同时会改变离子间的静电力，改变离子串震动的方式。

This also modifies the electric forces between the ions, changing the way the row vibrates.

离子晶体的单位化学式就是其中不同离子间的最简比。

The simplest ratio of the ions in thecrystal is known as the formula unit.

And, this minimum here is what gives us the value of the inter-electrode separation, the inter-ion separation.

这个最小值就是,电极间距离的值，离子间距离的值。

There is a repulsive force, the attractive force between ions of opposite charge is offset by a repulsive force due to electron cloud interactions.

有一个斥力时,存在于电性不同的离子间的引力,是可以被抵消的，因为电子可以相互影响。

So, for example, if I have a sodium ion over here, and I have a chloride ion over here, where the distance from center to center r I'm denoting as r, this is nucleus to nucleus separation.

所以，比如这有一个钠离子，和一个氯离子，它们中心与中心间的距离,我把它设为，这是原子核和原子和的间距。
