摘要：

 采用簇合物生长的自调整模型，并用扩散粒子的非均匀几率密度场模拟了簇合物和扩散粒子之间的非均匀相互作用势场, 研究了广义簇合物在非均匀场下的生长形态，考察了深度因子α、粘附参数t等对簇合物生长形态及对非均匀场的影响. 结果表明，非均匀场的性质是决定簇合物生长几何形态的主要因素，深度因子α决定了簇合物中生长形态的紧密程度，粘附参数t决定了致密程度，α、t等参数对场的作用有一定的影响

关键词: 广义簇合物, 非均匀几率密度场, 自调整模型

Abstract:

The morphologic characteristics of the clusters growth were studied by means of the model of self-adjusted growth of clusters under the field of nonhomogeneous potential which was simulated by the field of nonhomogeneous probability-density of the diffusion particles. The effects on the growth form of cluster as well as the field about the depth factorα, sticking coefficient t were investigated. The results show that properties of the field of nonhomogeneous potential are the main factors controlling the geomitrical morphologic characteristics of the clusters growth , the a and t factors have some effects on the action of the field. Theαfactor determines a dense extent and the t coefficient a compact extent for the growth form of cluster.
