这个最小值就是，电极间距离的值，离子间距离的值。

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

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.
