radiation-cooled tube

The results show that, in the coupled heat transfer of laminar developing flow of high temperature medium in a tube, the effects of thermal radiation on the velocity distribution and heat transfer intensity is obvious even though the optical thickness is not large.

结果表明，即使在不大的光学厚度下，热辐射作用对管内高温介质层流入口段耦合换热的速度场与换热强度都有明显影响。

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。
