研究了具有和不具有粒径分散性的二维Ising偶极粒子的吸引限制团簇-团簇聚集。观察到相对较小的集群的数量的快速减少。阈值浓度也被确定，根据该浓度下的动态聚集使用著名的Vicsek和家庭的动态标度理论解释。在阈值浓度以上，动力学取决于颗粒大小的分散性。此外，它建议，即使在稀释极限，动力学指数的影响，周围的集群之间的碰撞屏蔽两个集群。
The attraction-limited cluster-cluster aggregation of two-dimensional Ising dipolar particles with or without particle-size dispersity is studied. The fast decrease of the number of even-sized clusters for relatively smaller clusters is observed. The threshold concentration is also determined, under which the dynamics of aggregation is explained using the well-known dynamic scaling theory of Vicsek and Family. Above the threshold concentration, the dynamics depends on particle-size dispersity. Furthermore, it is suggested that, even in the dilute limit, the dynamic exponents are affected by the screening of the surrounding clusters on collision between two clusters.
