resonance tube

The separation distance between the nozzle and the resonance tube and the feed pressure of the driving gas were the main considerations. The validity of N-S equations, the distribution of flow parameters and aerodynamic force and the relation between axial force and separation distance have been analyzed.

实验中主要考虑喷嘴与谐振管间的分离距离以及供气压力的变化。分析了流场参数分布、气动力分布特性及轴向力随分离距离变化情况。

The resonance radiation trapping in alkaline-earth metal atomic lasers were investigated according to Holstein's theory. The threshold temperature, ground-state density and resonant level effective lifetime of the resonance radiation trapping were calculated for Ca, Sr, and Ba atomic vapor lasers with different tube radii.

根据Holstein理论研究了碱土金属原子激光中的共振辐射俘获效应，分别计算了Ca，Sr和Ba蒸气激光在不同半径时产生共振辐射俘获效应的阈值温度、基态粒子数密度和共振能级的有效寿命。
