A gas flow model with laser plasma as heat source was developed based on axial symmetric Euler equations in the laser propulsion rocket engine absorption chamber.

以轴对称非定常欧拉方程为基础，建立了激光推进火箭发动机吸收室内纯气相单组分、以激光等离子体为内热源的流场模型。

The energy absorption by the working gas, the radiation loss from plasma and the effect of working-chamber shape on the laser-sustained plasma characteristics are considered.

研究中考虑了工质对激光能量的吸收与辐射热损失，以及吸收室形状对激光维持等离子体特性的影响。

The authors of this paper developed a transient temperature measurement system of burnt gas in a combustion chamber based on the theory of absorption-emission.

根据辐射吸收法测温原理，作者研制了一套燃烧室内燃气瞬态温度测试系统。
