金作为催化剂直接置入封离型ＣＯ２激光器毛细管能有效地促使放电分解的ＣＯ２复合［１］，但也导致器件工作状态的改变［２］。作者从管内电场分布、有效放电等离子体体积及激励效率、迁移电流、双极性扩散、管壁电荷中和与壁电流等方面作了分析，用以自己的工艺镀制的环膜、离散膜及未置金催化剂管进行了比较实验，建立了器件的数学模型并编程数值计算，指出加入导体环膜后将降低器件效率，改变乃至恶化其运行状态，明确提出离散膜和弥散膜的概念并肯定其优越性，修正了前期工作所得“置入金环使着火电压与ＩＶ曲线都升高”的结论。
Gold as a catalyst directly into the capped CO2 laser capillaries can effectively promote the CO2 decomposition of the decomposition of the discharge [1], but also lead to changes in the working conditions of the device [2]. The author analyzed the electric field distribution in the tube, the volume and efficiency of the plasma, the excitation current, the bipolar diffusion, the wall charge neutralization and the wall current in the tube. And the catalyst without gold tube were compared. The mathematical model of the device and the numerical calculation were established. It was pointed out that adding the conductor ring film will reduce the efficiency of the device, change or even worsen the operating status, and clearly put forward the concept of the discrete film and the diffusion film Affirmed its superiority, amended the previous work income “into the Golden Circle so that the firing voltage and I V curve are increased” conclusion.
