于是就有了凝聚态物理中比较基础的有限粘结扩散模型(DLA),通过利用简单的随机行走和编程,任何人都可以利用电脑去模拟大自然的分形。 这里简单介绍一种简易的DLA模型:先画一个矩形框,比如100×80像素。在框里划分出精细的格子,比如每个各自的大小是1×1像素,而中央的格点在原点O=(0,0)处,在此处设置一个中央点。

8.1 Diffusion-Limited Aggregation 8.1.1 Basic Idea 时光易逝,容颜易老?且看度娘怎么说: 首先置一初始粒子作为种子,在远离种子的任意位置随机产生一个粒子使其做无规行走,直至与种子接触,成为集团的一部分;然后再随机产生一个粒子,重复上述过程,这样就可以得到足够大的DLA团簇(cluster)。
Natural growth of diffusion-limited aggregate (DLA), without any external stimuli, in boric acid doped starch system is reported here. Fractals grown were confirmed to be of diffusion-limited aggregate (DLA) pattern having fractal dimension ~1.49. Effect of substrate and humidity on growth pattern...

Starting from the explanation of diffusion-limited aggregation (DLA) model, we discuss various aspects of DLA; properties of the fractal structure, a variety of related phenomena, theoretical attempts to derive the fractal dimension expression, inherent stochasticity, extension and generalization of the ...
The development of the diffusion-limited aggregation (DLA) model by Witten and Sander1 has stimulated interest in a broad range of non-equilibrium growth and aggregation processes (see references 2–12 for recent books, reviews and conference proceedings). Since that time a wide range of physical...
