| 摘 要： | 采用光学发射谱（ＯＥＳ）技术对脉冲ＴＥＡ ＣＯ2激光诱发ＳｉＨ4＋ＣＨ4系统击穿产生的等离子体辐射进行了时间分辨的光谱测量。结果表明等离子体内分子的各碎片发光均在气体击穿时刻开始出现，但具有不同的时间特性，由此探讨了气体分子的分解过程。分析结果支持激光诱发ＳｉＨ4＋ＣＨ4等离子体内的主要离解通道为产生Ｓｉ，Ｃ原子通道的分解动力学机制的解释。据此观点讨论了气体分解碎片间的反应过程。实验与理论符合较好。

| Abstract: | The time-resolve optical emission spectroscopy is used to study silane and methane laser plasma. The results show that the different fragments' characteristic lines has the same appearance time but different temporal behaviours when the reactant breaks down. Based on the experimental results of dissociation processes it is suggested that the producing of Si and C atoms is the main dissociation channels of the reaction. |
