摘要
在扩散有限聚合模型中，引入噪声抑制、切向及法向随机因子等参数，将得到形态各异的分形图形。噪声抑制参数使局部场梯度很小的待生长位点成为生长点的概率更小，但引入切向随机因子后，噪声抑制的增加只使生长图形变密，图形总体形态大体不变。
Various fractal morphologies are obtained by lcading noise reduction, tangential and radialprobabilities into DLA(Diffusion-Limited Aggregation).As the nolse is reduced, perimeter sites withextremely small values of local field gradient are extremely unlikely to be chosen. But under tangentialprobability, the noise reduction only makes patterns to become dense. And the structure of patternshardly changes.
