[Study on micro-behaviours shock ignition for epoxypropane using spectrum techniques].

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.
