这里描述的是由聚集颗粒引起的混沌行为产生的图案。“聚集”是用于描述由扩散颗粒的附聚引起的生长的术语。在1981年,维滕和桑德开发了一个计算机模型的聚集开始于一个单一的种子粒子在一个空间的中心[1]。他们的计算机程序引入了一种新的粒子,这种粒子随机移动,直到它接近另一个粒子并粘在它上面。第一个粒子附着在种子上,但很快就形成了一个分支,分形结构,维数约为1.7。这个过程被称为扩散限制聚集(DLA)。自1981年Witten-Sander模型提出以来,人们对DLA的性质进行了大量的研究[2-6]。在这里的图表中,额外的轮廓线为科学家提供了关于生长过程的额外信息。
Described here is a pattern produced by chaotic behavior arising from aggregating particles. “Aggregation” is a term used to describe growth arising from the agglomeration of diffusing particles. In 1981, Witten and Sander developed a computer model for aggregation starting with a single seed particle at the center of a space [1]. Their computer program introduces a new particle which moves randomly until it approaches another particle and sticks to it. The first particles attach to the seed, but soon a branched, fractal structure evolves with a dimension of about 1.7. This process is calleddiffusion limited aggregation(DLA). Since the introduction of the Witten-Sander model in 1981, considerable research has been devoted to the properties of DLA [2–6]. In the diagram here, the additional contour lines give extra information to scientists concerning the growth process.
