| 摘 要： | 利用高温热解SiH4的方法获得气相Si原子，然后通过气相Si原子与N2O反应成功得到了亚稳态储能粒子SiO(bb3П)。通过不断地改进装置和实验探索，掌握了该合成反应的实验规律，并对实验条件进行了优化。N2O与SiH4的流量配比在8~10，SiH4稀释比在0.3%左右，热解温度在1 160～1 170 ℃时，得到了最强的光谱信号。

| Abstract: | Silicon atom was obtained by pyrolysis of silane and then reacted with N2O to produce the metastable state storage medium-SiO (b3П). An improved experiment device was set up and the optimal experiment parameters were achieved through plenty of experiments. Based on the present experiment device, when the ratio of the flow of N2O and SiH4 is 8～10，the SiH4 is diluted to 0.3% and the temperature of the oven is in the range of 1 160~1 170 ℃, the intensity of the spectrum measured in the experiment is the strongest. |
