But now it's going to make more sense because in that case we were just talking about single electron atoms, and now we're talking about a case where we actually can see shielding.

但是现在能讲得通了,因为在那个情况中我们仅仅是现在我们讨论的是,讨论单电子原子，看到屏蔽的案例,我们能看到屏蔽。

So, what we can do is figure out what we would expect the binding energy of that electron to be in the case of this total shielding.

完全屏蔽的案例中,期望的电子结合,能再次记住,结合能物理上来说是。

And this is absolutely confirming that what is happening is what we would expect to happen, because we would expect the case of reality is that, in fact, some shielding is going on, but it's not going to be total shielding, but at the same time it's not going to be no shielding at all.

因为我们期望看到的真实情况是,事实上,一些屏蔽发生了,但它不是完全的屏蔽，但与此同时它也不是，一点屏蔽也没有,如果我们从实验中得到电离能是多少。

And if we do that calculation, what we find out is that the binding energy, in this case where we have no shielding, 72× is negative 8 . 7 2 times 10 to So, let's compare what we've just seen as our two extremes.

我们会发现结合，能在这个情况中，没有屏蔽，等于-8。,所以我们来对比一下,我们在两个极端的案例中看到了什么。

In an extreme case b, we had a z effective of 2, so essentially what we had was no shielding at all.

我们有效的z是，所以本质上我们完全没有屏蔽。
