荷电粒子对分形结构的影响

Effects of Charge Particles on The Fractal Structure

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。

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.
