Well, the reason, the way that we can check it is just to see if it's in between our two extreme 1 cases. We know that it has to be more than 1, because even if we had total shielding, 1 we would at least feel is the effective of 1.

好的我们可以检查它的原因和方式是观察,它是否在我们的两种极端案例之间,我们知道它必须大于，因为即使如果我们有完全的屏蔽，我们最小感到的有效值是。

So again, when we check these, what we want to see is that our z effective falls in between the two extreme cases that we could envision for shielding.

所以当我们再一次检查这些时，我们想看到的是,有效电荷量处于两种极端案例中,这两种极端案例。

The electron completely canceled out 1 it's equivalent of charge from the nucleus, such that we only saw in a z effective of 1.

电子完全抵消了来自原子核的等量电荷,这样我们仅仅看到有效的z为，在极端案例b中。
