M- Luxman T-117 - Very good-sounding tuner. No real faults, top to bottom. Not as three-dimensional as the L-02T and gives up some bass richness.

力士的T-117，非常好声的收音头，从高频到低频几乎没有缺憾，三维声场不如建伍的L-02T，而且也放弃了一些低频的浓郁度。

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
