In this paper,the concepts of limit set,cluster set of L-net were introduced in the topological molecular lattices,many properties of molecular net were extended.
在拓扑分子格中引入了L 网的极限集、凝聚集等概念,推广了拓扑分子格中分子网的诸多性质,并以L 网为工具,刻划了拓扑分子格中T2分离性、紧性与次紧性。
First, the concepts of limit set, cluster set of L-.
在拓扑分子格中提出L-网的极限集、凝聚集等概念，系统地讨论它的收敛性、L-网与生成滤子之间的关系，推广原有L-网的性质。
Beginning with the point of statistic and basing on the model of DLA,this paper studies the assemble-growth aggregation with foursquare four sides’ midpoint as random particles generate positions.
从统计的角度出发,在二维DLA模型的基础上,以正方形四边中点作为随机粒子产生位置的聚集生长凝聚集团进行研究,测量在不同粒子数情况下凝聚集团的平均特征长度,寻找平均特征长度与粒子数之间的关系。
For many natural aggregations, considering the particle-source of aggregations don’t always have the characteristic of symmetry like the traditional DLA model, they can be in one direction of their aggregations.
这可能会对凝聚集团的生长产生影响,使得集团与传统DLA模型集团存在某些差异,而这些差异又可能蕴含着粒子源的某种信息。
