No, we can't. Because if l equals 1, we can not have m sub l equal negative 2, right, because the magnetic quantum number only goes from negative l to positive l here.

不行，因为如果ｌ等于１,ｍｌ的值不可能等于－２，对吧，因为磁量子数的值,这时只能从－１到１

So this means we can only have 2 different values of l.

这就意味着我们只有２个不同的ｌ值。

s We are back over to E as a function of n, l, m and s, only we got there through this other torturous route.

我们回到将E作为函数n，l和，只要我们解决了这个烦人的路径。

Again, the reason for that is because the energy only depends on the n value here, it doesn't depend on l or on m.

因为，能量,只和n的值有关，与l和m的值无关。

And what you can see is that 0 for any n that has an l equals 0, you can see here how there's only one possibility for and orbital description, and that's why we don't need to include the m m when we're talking about and s orbital.

你们可以看到,对于任何n，如果l等于，你们从这里可以看到，只有，一种,可能的轨道描述，所以,当讨论s轨道的时候,不需要考虑。
