通过计算机模拟对随机集料模型进行了研究。该模型适用于以前测量过关联的金属-粒子聚集过程。与金属聚集体的密度关联一样，模型聚集体内的密度关联随着距离的增加而按分数幂规律下降。模型集料的回转半径呈幂函数行为。该模型是枝晶生长模型的一个极限。
A model for random aggregates is studied by computer simulation. The model is applicable to a metal-particle aggregation process whose correlations have been measured previously. Density correlations within the model aggregates fall off with distance with a fractional power law, like those of the metal aggregates. The radius of gyration of the model aggregates has power-law behavior. The model is a limit of a model of dendritic growth.
