摘要

摘要: 利用多种光谱技术，提出了一种确定燃料冲击点火延迟时间的新方法。用这种方法所获得的实验值比国内外常用光电二极管（峰值波长约在800 nm）方法的所测值更接近实际值。环氧丙烷受冲击后，反应中间产物出现的时间是不同的，辐射强度也不同。在冲击波作用下，基团出现的顺序便可确定，它们依次为O、CH2O、C2、CH、CH3O、CO2、H2O等，而O原子总是首先出现。

Abstract: A new spectroscopic technique is introduced to measure the delay time of the shock ignition of epoxypropane. Intermediate product of the most early emergence for the loaded fuel is determined at first using spectrometer, because the intermediate product of O for epoxypropane after shock ignition is always emerged early. Then the monochrometer is adjusted to 436.8 nm (or 395.46 nm, 394.7 nm) wavelength of O, and the arrival time of shock wave is measured by gauge. The delay time of shock ignition for epoxypropane is determined. The delay time determined by the method is closer than that of using photo-electric diode whose peak wavelength is about 800 nm. The measured results show that the emergence times of intermediate product of O for epoxypropane after shock ignition are different, and radiation intensities for the radicals are also different. The emergence times for O, CH2O, C2, CH, CH3O, CO2, H2O radicals are obtained after the shock wave enters into the epoxypropane. Oxygen atoms are always presented first.
