反转机理 meaning in Chinese

inversion mechanism

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，讨论了二氧化碳激光粒子数的反转机理，包括电子碰撞激励、激发态n2分子等共振转换激励过程，激光上下能级co2 ( 00 1 ， 10 0 )以及最低能级co2 ( 0110 )的弛豫过程等几个方面
