摘　　要：采集了南京市区不同的路面积尘试样,进行了试样的粒径与元素的相应实验分析,得出了相应的粒径分布规律、元素组成和元素含量;并对路面积尘的应用基低热值和分形维数进行了分析和计算,其应用基低热值在5 385.0-7 366.6 kJ/kg之间,分形维数为2.302-2.541,为路面积尘的直接能源化利用和卫生填埋提供了依据.Different samples of road dust are taken in Nanjing city. Corresponding experiments on particle diameter and elemental components of these samples are performed to obtain distributions of particle diameters, elemental components and levels. Low-calorie-value of arrived basis and fractal dimension of road dust are computed and analyzed where lowcalorie-value of arrived basis ranges from 5 385.0 kJ/kg to 7 366. 6 kJ/kg and fractal dimension fluctuates between 2. 302 and 2. 541. This provides fundamental information for direct energy utilization and sanitary landfill of road dust.
