摘要
使用光学多道分析仪（ＯＭＡ）详细收集了氢氧气体爆炸产物激励下，两种不同粒度的铝粉在不同氧含量条件下快速反应的低分辨和高分辨光谱。实验结果表明在２４０～８５０ｎｍ的光谱范围内的辐射以连续辐射为主，并有较弱的铝原子线和ＡｌＯ的Ｂ２Σ＋→Ｘ２Σ＋带光谱。
Optical multichannel analyzer(OMA) was used to investigate the emission spectra from the fast reaction of aluminum powders driven by hydrogen oxygen detonation in shock tube. The spectra from the reactions of two sizes of aluminum powders throughout of the 240～850 nm wavelength region has been determined experimentally with a resolution of 0 6nm at various pressures. Higher resolution(0 071nm resolution) spectroscopic were also made in several region of interest in the 240 ～850 nm wavelegth region. The spectra measurements in this study were dominated by continuum radiation. The intense blue green emission of the AlO B 2Σ +→X 2Σ + transition was also present.
