用法例句

Based on the L-S coupling approximation.

本文根据同科电子在L-S耦合下量子数取值的组合特点,推出了总轨道磁量子数为ML时出现次数的计算公式,结合Maple数学软件,给出了一种推求同科电子光谱项的新方法。

In the many-electron system,for L-S coupling,ground-state spectroscopic term of atom is determined by two situations,one is configuration of equivalent electron,the other is configuration of non-equivalent electron.

原子的基态光谱项是由原子外层电子的组态的耦合决定的,在L-S耦合时,对多电子体系,原子基态光谱项的确定分两种情况,一是同科电子的组态,二是非同科电子的组态,由于受泡利不相容原理的限制,两种组态基态光谱项的确定方法不同。

This paper raises a delete principle which infering the spectral term of five equal electrons system in L-S couple and gives a certificating.
