摘　　要：火灾中聚合物材料的燃烧过程产生的热解产物,从而增加化学分析谱图的复杂性,对助燃剂鉴定造成干扰。针对常见的聚合物材料开展了一系列燃烧实验,对其在燃烧过程中的热解机理进行了分析,并通过汽油存在条件下的聚合物材料燃烧实验分析了热解对汽油辨识产生的干扰。Pyrolysis products generated in combustion of polymer materials may complicate the interpretation of chromatograms. In this work, a series of combustion experiments were conducted to study the pyrolysis products of typical polymers in fires, and the pyrolysis mechanisms involved were analyzed. Also the combustion experiments of polymers were conducted under the presence of gasoline, by which the impact of pyrolysis products on the gasoline identification was studied.
