random motion

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.

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。

The stochastic chaotic motion and the threshold parameter value for ships onset chaotic motion in random beam waves are studied by the probability density function and the numerical method.
