Abstract: We report the effects of charge particles on the fractal structure based on the Diffusion-Limited Aggregation(DLA) model. The dimensions of fractal structures become larger and the shapes of fractal structures alse change, in pace with the increase of the chargeability P in the scope of P≤30%. The reasons of the effects are discussed preliminarily.

Key words: diffusion-limited aggregation(DLA) model, charge particles, fractal dimension

摘要: 在有限扩散凝聚(DLA)模型基础上,讨论了部分粒子荷电对分形结构的影响。在一定荷电几率范围内(荷电几率P≤30%),分形结构的维数随着粒子荷电几率的增加而增大,且分形结构的形状亦同时发生变化。给出了粒子荷电使分维增大的初步解释。
