| 摘 要： | 本文利用能量一级近似模型，分析研究了轴快流CO2激光器中的气体温升，获得了与实验相符的结果。提出在轴快浇CO2激光器中，气体快速流动不仅可获得较大的热容量液，而且在放电过程中还可以将部分热能转化成气流本身的动能，从而减小气体的温升。定量地给出了气体温度与放电功率、热容量流和气流速度的关系式。

| Abstract: | The temperature rise in fast axial flow CO2 lasers has been studied with first-order approximation of energy. The theoretical resuls tare in agreement with the experiments. Driving the gas to flow fast can not only increase the heat capacity flow rate but also convert partial waste heat to gas kinetic energy, hy which the temperature rise in laser tubes can be restrained to a great extent.A simple expression, which relates the temperature rise to the gas speed, the heat capacity flow rate and the discharge power, is quantitatively presented. |
