摘要：
We investigate the diffusion limited aggregation of particles executing persistent random walks. The scaling properties of both random walks and large aggregates are presented. The aggregates exhibit a crossover between ballistic and diffusion limited aggregation models. A non-trivial scaling relation E e "5 between the characteristic size in which the cluster undergoes a morphological transition, and the persistence length e, between ballistic and diffusive regimes of the random walk, is observed. 0 2011 Elsevier BM.
