And this spin magnetic quantum number we abbreviate as m sub s, so that's to differentiate from m sub l.

这个自旋磁量子数我们把它简写成ｍ下标ｓ,以和ｍ小标ｌ有所区分。

The violin string extends from x equals zero to x equals L, and we pluck the violin string.

弦从X轴指向原点,让x等于L，然后我们拉直那根弦。

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

And that's just to take 1 the principle quantum number l and subtract it by 1, and then also subtract from that your l quantum number.

主量子数,减去,再减去，量子数,你们可以对1s轨道来验证一下。
