| 摘 要： | 利用多台单色仪、光电系统及高速数据采集系统，成功地研究了硝基甲烷和氧混合物点火后快速反应的光谱。实验观察到CH3O、CH、CH2O、OH、CHO、CO、CO2、H2O、NO、NO2等中间产物及最终产物的辐射。时间分辨的光谱测量发现：在爆炸激波管中，硝基甲烷快速反应的机理明显不同于硝基甲烷热分解和冲击引爆时的结果。

| Abstract: | High speed reaction spectra ignited for the mixture of nitromethane and oxygen aresuccessfully studied by using multi-monochromator , photoelectric system and high speed data ac-quisition system. Both intermediates and termination products , for example , CH_3O,CH, CH_2O,CO,H_2O,CO_2 , NO,NO_2 , and so on , are observed.It is found using spectrum measurements withtime-resolution that the mechanism of high speed reaction for nitromethane in explosion shocktube is different from that of heat dissociation and shock initiation. |
