摘要: 本文用KODAK-2485胶片拍摄了激波管内四种烃燃料（正庚烷、异辛烷、M-17乳化汽油、W-11乳化汽油）的爆轰光谱。发射光谱由爆轰产物产生的连续光谱，Fe、Cr、Mn原子的大量线光谱，以及550~660 nm强而复杂的带光谱组成。经分析，在这些带光谱中存在FeO分子的黄带系光谱。

Abstract: The KODAK-2485 film is used to study the impurity spectrum appeared in the detonation spectrum of four hydracarbon fuels (heptane, isooctane, M-17 and W-11 emulsification) mixed with oxygen (or nitrogen). The emission spectra consists of the continuous emission spectra from detonation products, spectral lines of Fe, Cr, Mn atom, and a series of strong and complex bands in the range 550~660 nm, in which exist orange bands for FeO molecules.
