Sample method for scatter angle of electron collision in gas discharge 氣體放電中電子碰撞散射角的抽樣方法
The second part is about co2 lasers . we first discuss the mechanisms of population inversion , including excitations and relaxations ( electron collision excitation , resonance transition excitation impacted by excited n2 molecules , the relaxation of both the lower - upper laser levels and the lowest level of co2 ) 首先,討論了二氧化碳激光粒子數(shù)的反轉(zhuǎn)機(jī)理,包括電子碰撞激勵(lì)、激發(fā)態(tài)n2分子等共振轉(zhuǎn)換激勵(lì)過程,激光上下能級(jí)co2 ( 00 1 , 10 0 )以及最低能級(jí)co2 ( 0110 )的弛豫過程等幾個(gè)方面
