Abell-ACO团二维分布中的结构

The Structure in the Two-Dimensional Distribution of Abell-ACO Clusters

本文用团分析法分别对距离类D＝5及D＝6的Abell－ACO团的二维分布进行了分析．分析的目的是探讨星系团分布中可能存在的超大尺度结构．分析结果表明：富星系团分布中的确存在尺度≥100h-1Mpc的超大尺度结构．本文的分析为超大尺度结构的存在提供了又一支持．

In this paper, we study the structure in the two-dimensional distribution of Abell-ACO clusters of distance classes D = 5 and D = 6 by using cluster analysis. The intention is to explore the ekistences of super-large-scale structures in the distribution of the clusters. The results show that there are real structures on the scale of≥ 100h-1 Mpc in the distribution of rich clusters. This provides an additional evidence for the existence of super-large- scale structures.
