The atoms are excited by these collisions, and they typically emit light as they return to their original energylevel.
原子被这些碰撞而激发，它们为了返回原来的能级，通常会发出光亮。

The energy was excited to a level never seen before.
这一能量被激活到一个前所未有的水平。

Our results suggested that the research of polarizedluminance will benefit the study of excited and exciting energylevel, transition probability, and delay mechanism in nano semiconductor.
