摘要
通过对胶体扩散控制聚集机理的MonteCarlo模拟，表明粒子簇的布朗扩散系数与其大小和形状有关，粒子簇的大小分布可被标度．在微观或介观的层次上，揭示了表征粒子簇结构的几何形状因子在扩散控制聚集过程中对动态标度和粒子簇分布的影响．
The diffusion-limited aggregation mechanism was simulated by using Monte Carlo method- Brownian diffusion coefficient depends on the cluster size and morphology. Thecluster size distribution can be scalled, which agrees with experiment result. The effect of geometric morphology on the cluster size dynamic scaling and distribution was studied on the level of the microscope.
