摘要: 利用DLA模型,研究平行力场对凝聚物生长的影响.结果表明:力场使凝聚物的生长失去对称性,粒子凝聚密度增加,且引力场越强,密度值越大;同时凝聚生长出现不可再生长区域,凝聚物生长迅速由生长区过渡到饱和区.

关键词: 分形, 平行引力场, 凝聚物, 粒子密度

Abstract: In diffusion limited aggregation( DLA) model,particle aggregation in parallel field is investigated. It shows that symmetry of particle aggregation is destroyed and particle density is increased. Aggregation pattern transforms fractal into compaction and growth location of aggregation transforms into saturated growth region. As intensity of parallel force field is stronger,aggregation grows faster and particle density is higher.

Key words: fractal, parallel force field, aggregation, particle density
