Using two-step laser excitation, we obtained the spectrum of highly excited nf series of Al. Stark effect induced forbidden transition lines, line shifts and line broadening are also observed. The theoretical analysis is presented. 利用两步激光激励,得到Al原子高激发态nf系列的谱线,观察到由于Stark效应引起的禁戒跃迁线的产生,谱线位移与谱线放宽,并给出初步的理论分析。
As shoot often happens near forbidden zone, and forbidden zone lines in a long-view shot can be detected to find forbidden zone, which can help shoot event detection. 射门事件通常是在禁区附近发生的,本文通过检测禁区线实现对禁区的检测,从而辅助射门事件的检测。
