摘　　要：以二维DLA模型为基础,发展了一个多集团聚集生长模型,并且利用该模型模拟研究了在二维欧氏平面内多个凝聚集团同时聚集生长的情况。模拟结果显示:集团与集团间存在不可忽略的影响,使得不同区域内集团形态各异;集团间存在生长概率几乎为零的区域;这种相互作用并不影响集团的分形维数。A aggregate growth model of multi-aggregation was developed based on 2-dimension DLA model. And the multi-aggregation growth on the 2-dimension Euclidean plane was simulated with the aggregate growth model,Tne simulation results showed that there was a crucial impact among the aggregations, which made the morphology of aggregations different. Tnere were some regions whose growth rate was zero nearly, But the interaction didn＇t impact fractal dimension of aggregations.
