摘要
建立了一个分形聚集的粒子-集团模型(径向分层聚集模型).研究了外场中的分形聚集性质,提出了一个关于分形聚集的阈值的证据.计算机模拟结果表明,阈值占据概率Pac=0.67±0.03,分形维数Dc=1.70±0.02.
A particlecluster mode (radial shellshells aggregation model) for fractal aggregation has been developed. The properties of fractal aggregation in the external fields are investigated, and a proof of a threshold value existing in the fractal aggregation is proposed. Computer simulation results show that the concentration of the threshold value is Pac=0.67±0.03 and the fractal dimension is Dc=1.70±0.02.
