抄録

Computer simulations have been conducted to investigate the cluster formation process. Clusters can be expressed with some indices, including new ones. Growth of diffusion-limited aggregation (DLA) and ballistic aggregation (BA) are characterized by their indices, for example, cluster diameter, fractal dimension (D), density distribution along radius and so on. As the consequences of comparison between the both types of clusters, BA seems to be more harmful than DLA. Particle jump length (L) affects the cluster formation. When L is situated middle between DLA and BA, values of D, cluster diameter and cluster shape are also intermediate. From the fact that these new indices have great influence on structure formation, we can get possibility to identify the process which the clusters are generated in.
