摘要
在由光学多道分析仪收集的氢氧气体爆轰激励下铝粉快速反应光谱中，观察到ＡｌＯＢ２Σ＋→Ｘ２Σ＋跃迁Δｖ＝０带系的光谱特征与通常铝氧化反应的光谱特征不同。经分析是因为存在一个从４６７ｎｍ开始向长波方增强的连续辐射，它改变了该波长区ＡｌＯ分子的辐射特征。这一连续辐射可能是由铝与水蒸汽发生水合反应生成。
The optical multichannel analyzer(OMA) was used to investigate the radiation emitted from the fast reaction of aluminium dust ignited by hydrogen-oxygen gas detonation in shock tube.An intense blue-green emission of the AlO B 2Σ +→X 2Σ + transition was observed.The spectra in the region of the Δν=0 of AlO B 2Σ +→X 2Σ + transition are very differant from the radiation from aluminium oxide.By analyse,these is an intense continum in creasing with wavelength,which has short wavelength 446nm in the region.The continua radiation may be assigned to an aluminium monodydroxide-HAlO,which is the product of hydration reaction.
