采集黄岛区主要相关区域的大气颗粒物样本分析了大气颗粒物分形特征.实验结果表明:分形维数越大的颗粒物中细颗粒物含量越高;越高层的细节信号中分离出的大粒径颗粒物越多;颗粒物的分形维数与球形度呈反比关系,与比表面积成正比关系.

Collecting atmospheric particulates from mainly related areas of Huangdao district,and analyzing the atmospheric particulates' fractal feature.Results indicate that:Larger fractal dimension of the particulates includes more fine particulate matter;Higher level's detail signal of atmospheric particulates includes more large diameter particles;There is a inverse relation between fractal dimension and degree of sphericility,and a positive relationship between fractal dimension and specific surface area.
