And if we experimentally know z what the ionization energy is, we actually have a way to find out what the z effective will be equal to.

我们实际上就有了一个办法,去找出有效的，等于多少,我们可以使用这里的方程。

So z equals 7 -- this is the cut-off where, in fact, the sigma orbital is going to be higher in energy than the pi 2 p orbitals.

所以z等于7-这是分界点，实际上，sigma轨道能量,要比π2p轨道高。

bug Now, this was not the bug in this program because I did, in fact, use the equality operator and so it feels like if I type the word foo both times I should, in fact, get back you type the same thing.

现在，在这个程序中这个不是，因为，实际上，我使用了等于号,如果我输入单词foo两次，我返回给你“输入了相同的东西“
