摘　　要：采用气相色谱-质谱联用(GC-MS)分析技术对92#汽油燃烧残留物进行分析。实验结果表明随着燃烧时间增加,芳香烃和稠环芳烃类组分含量减少,多环芳烃类组分含量增加,茚满类组分含量较为稳定,不同的燃烧时间会对汽油燃烧残留物特征组分的鉴定产生不同的影响。实验结果可以为汽油燃烧残留物火灾物证鉴定工作提供参考。The analytical technology of gas chromatography - mass spectrometry （GC - MS） was applied to analyze the combustion residues of 92# gasoline in this paper. The experimental results showed that with the increase of burning time, the aromatic hydrocarbon components and some specific polycyclic aromatic hydrocarbon components decreased, some polycyclic aromatic hydrocarbon components increased, the indan components were relatively stable, and different burning time would bring different effects to the identification of the characteristic components of the gasoline combustion residue. The results provided reference for the physical evidence identification of gasoline combustion residue.
