介绍了一种描述团簇聚集生长过程的模型，并用蒙特卡罗方法对其进行了研究。结果表明，这些团簇具有标度不变性。这类新的动力学临界行为在d=2维上的分维为D=ν−1=1.3 8±0.0 6，由团聚体的回转半径和密度关联决定.将该过程与其他类型的动力学和平衡临界现象进行了比较。
A model describing the process of cluster growth by aggregation of clusters is introduced and investigated with the Monte Carlo method. It is found that the clusters are scale invariant. The fractal dimension of this new class of kinetic critical behavior is D= ν− 1= 1.38±0.06 in d= 2 dimensions as determined by the radii of gyration and the density correlations of the aggregates. The process is compared with other types of kinetic and equilibrium critical phenomena.
