[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,CH_2O,C_2,CH,CH_3O,CO_2 and H_2O 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.
