摘要
在局部区域粒子源聚集生长模型的基础上,通过对凝聚集团的生长平面进行区域划分,研究了局部区域粒子源凝聚集团在生长平面内各区域的粒子密度分布情况。结果显示:凝聚集团大多数粒子均聚集于生长平面的中心区域,越远离区域中心,粒子数越来越少;另外,越接近种粒子区域,集团的粒子在生长平面内的面密度值越大,且其最大值出现在种粒子所在的区域,而不是生长平面的中心。该结果可能有助于找到凝聚集团生长的种粒子,从而判断粒子的来源,了解凝聚物生长的历史环境。
Basing on the growth model of local particle source, the particle density distribution of local area particle source aggregation in each area of growth plane are studied, by dividing the growth plane of aggregation for region. The results show that ： the most particles of aggregation are gathered in the central area of the growth plane, the more far away from regional center, particle number is less ; In addition, the more closer to the seed particle ar- ea, the growth plane density value of particles is larger, and the maximum value appeared in the particle area, rather than the center of the growth plane. The results may help to find the seed particle of the aggregation, and judge the source of particles, and understand th,~ th hi~ ;
