| 摘 要： | 以DLA模型为基础,模拟研究了在二维欧几里德平面上由局部区域内产生随机运动粒子的聚集生长过程,发现对于足够大的粒子运动区域和足够远的粒子源距离,凝聚集团大体上被限制在欧氏圆形面内,圆心在粒子源对称中心和种粒子的连线上,且比种粒子更加接近粒子源;凝聚集团朝各个方向的平均生长速率虽然不同,但整体仍呈分形结构。

| Abstract: | Based on the model of DLA,this paper simulates the process of aggregation's growth for random walk particles from local area on two-dimension Euclidean plane.The aggregation is confined to Euclidean circular plane for large enough particle walking area and far enough partial source distance.The centre of the Euclidean circular plane is on the line between the particle source's symmetric centre and the seed particle,and is more closer to the particle source than the seed particle.Though the rate of aggregation growth is different in different directions,the whole aggregation shows fractal structure. |
