collision excitation meaning in English

碰撞激发

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
Since the carrier mobility in organic materials is very low , no collision excitation is possible . the short wavelength peak is due to direct bombardment by electrons from sic > 2 . we name this luminescence as cathodoluminescence - like ( cl - like ) emission or solid state cathode luminescence because the energized electrons are accelerated in solid instead of in vacuum
这样在有机层中的电子数是nl n计n汁n ，空穴数是p n （ n是类阴极射线激发出的电子，也是类阴极射线激发出的空穴儿这两类载流子的复合将比单纯有机发光的复合nip增加了（ n计n叶n ）叮（ l n计n叶n ） n 。
