用多种谱仪技术研究环氧丙烷点火的微观特性

Study on Micro-Behaviours Shock Ignition for Epoxypropane Using Spectrum Techniques

利用OMA(光多通道分析系统)谱仪和单色谱仪技术研究了环氧丙烷冲击点火的微观特性。OMA谱仪观察到O,CH2O,C2,CH,CH3O,CO2,H2O等许多中间产物和最终产物。利用三台单色谱仪和压力传感器确定环氧丙烷冲击点火后这些产物出现的顺序并确定了它们的点火延迟时间和临界条件。

The micro-behaviours of shock ignition of epoxypropane were studied by OMA（optical multii channal system） and monochromator techniques. The radicals O, CH2O, C2, CH, CH3O, CO2 and H2O were observed by OMA spectrometer. The delay time and critical condition of shock ignition were determined using three monochromators and gauge. The emergence of intermediate product of O for epoxypropane after shock ignition is always the earliest.
