摘要
对于纵火火灾调查,在火场中检测出的易燃液体残留物可在很大程度上给案件定性.从火场提取的易燃液体残留物存在挥发效应,会在一定程度上阻碍火场易燃液体及其残留物的鉴定.以易燃液体及其燃烧残留物为研究对象,阐述了不同条件(温度和基质)下,挥发效应对火场易燃液体及其燃烧残留物物质变化和鉴定的影响,介绍了仪器分析和数据分析手段对易燃液体及其残留物挥发干扰因素的消除,并对未来火场易燃液体的鉴定提出了一些建议(引用文献44篇).
Abstract
For the investigation of an arson fire,the case was largely classified with the flammable liquid residues detected at the fire scene.However,flammable liquid residues extracted from fire scence often had weathering effect,which hindered the identification of the flammable liquids and their residues.Flammable liquids and their combustion residues were used as the object,describing the weathering effect on changes in the substance of flammable liquids and their combustion residues at fire scenes and on their identification under different conditions(temperature and substrate),and the analytical methods of instrument and data were introduced to eliminate the weathering interference factors of flammable liquids and their residues.Some suggestions were given for the further identification of flammable liquids at fire scenes(44 ref.cited).
