本文研究了由TEA CO_2激光器产生的单脉冲红外激光引爆NH_3-CH_4-O_2的反应,测定了不同气体混合物的组成比、总压力及激光频率对引爆所需的最低激光能量密度(引爆阈值)的影响.还对存在Pt-10％Rh表面的上述体系进行了研究,发现金属表面能降低引爆阈值.但复相反应与均相反应所得的反应产物相同,主要是N_3,H_2O和CO_2,而且在反应过程中都产生强烈的黄色闪光. In this paper, the reaction of NH_3-CH_4-O_2 detonated by a single pulse infrared laser generated by a TEA CO_2 laser was studied. The composition ratio, total pressure and laser frequency of different gases were measured to determine the minimum laser energy detonation threshold (detonation threshold) The above system was also investigated for the presence of Pt-10% Rh surface and found that the metal surface can reduce the detonation threshold.But the complex reaction with the homogeneous reaction of the same reaction products, mainly N_3, H_2O and CO_2, and in During the reaction have a strong yellow flash.
