在Visual-Basic平台下实现DLA分形生长的模拟

Simulation for the Fractal Growth on the Platform of Visual-Basic

简要概述了扩散置限聚集(Diffusion Limited Aggregation,简称DLA)模型的物理机制和分形维数的计算方法,给出该模型的计算机算法和在Visual-Basic平台下的程序设计,在Windows操作系统下实现了DLA模拟生长的动态过程,在程序中避免伪随机的产生,并尽可能实现等概率的生长.

This paper describes the physical principle of Diffusion Limited Aggregation（DLA） and the calculational method of fractal dimension, giving out the computer arithmetic of this model and the program design on the platform of Visual-Basic, actualizing the simulation of DLA dynamic growth process, avoiding false random emergence, and actualizing equiprobable growth as possible.
