| 摘 要： | 在搭建的试验房间顶部及墙壁上布置一系列采样板,模拟火灾现场中易燃液体燃烧烟气的蔓延和吸附情况,然后定量提取采样板上吸附的烟尘,并利用GC/MS进行定量成分分析,根据采样板上烟气特征成分的含量,确定易燃液体燃烧烟气在不同空间位置的沉积规律,从而确定火场勘查中物证提取的最佳位置。试验结果表明,火源上部正对火源处为最佳提取位置,同时还可提取墙角处,以及距火源最近的壁面和顶面交汇处的烟尘。

| Abstract: | A series of sampling boards were laid at the ceiling and wall of a room set up for experiment.The spread and adsorption of burning flammable liquids smoke at fire scene were simulated.The dust on the sampling board was quantitatively extracted,and the GC/MS was used for quantitative component analysis.According to the characteristic component contents of smoke on sampling board,the deposit laws of burning flammable liquids smoke at different spatial location were determined,and the best locations for eviden... |
