| Abstract: | The fractal characteristics of aerosol particles and the significance of studying of atmospheric aerosol property were analyzed.Based on the Diffusion-Limited Aggregation(DLA) model,the fractal aerosol aggregation particles with different number of original particles aggregation growth was simulated,and the simulated results were compared with the experimental observation results which verify the reliability of the simulation results.Final,the variation curve of fractal dimension of aggregation particles changed with the number of original particles was given and the result shows that the number of original particles affect the fractal dimension of aggregation particles directly. |
