| 摘 要： | 对火灾现场常见聚合物材料和易燃液体燃烧烟尘凝团进行了分形研究,通过线性回归得到了描述其形貌特征的分形维数和分形前置因子。研究发现大多数材料烟尘凝团的分形维数在1.5~2.0之间,燃烧时发烟量较大的材料通常具有较高的分形维数值。利用分形分析结论,对烟尘进行判别分析,可以准确判别烟尘种类。

| Abstract: | In this paper, fractal analysis method is used to study the soot sample of fires for common polymeric materials and liquid fuels. Fractal dimensions and fractal prefactors are obtained by linear regressions. The results show that the fractal dimensions for most materials fall into the range of 1.5~2.0. Rich burning soot materials usually have higher values of fractal dimensions. It is concluded that fractal analysis method can be used to distinguish the type of burning soot. |
