摘要(Abstract)：
开展对典型可燃物燃烧烟尘的物化特性差异性研究,是全面了解烟尘信息的基础。基于可控条件下的燃烧试验,对典型可燃物燃烧烟尘物理特性和化学组分进行了分析。通过对比分析汽油燃烧烟尘、聚苯乙烯燃烧烟尘、ABS燃烧烟尘及柴油烟尘和正庚烷烟尘的透射电镜图片,对透射电镜图的紧凑性、复杂性及灰度值进行了深入分析,探讨了燃烧烟尘的物理差异性。利用固相微萃取-气质联用技术(SPME-GC-MS),对汽油燃烧烟尘、聚苯乙烯燃烧烟尘、ABS燃烧烟尘化学组分进行了分析和对比。通过燃烧烟尘的特征物质组分的分析,得到3种燃烧烟尘在特征物质的分布和出峰时间等方面的差异性。这些差异性可作为对烟尘来源及燃烧条件等因素判别的依据。
