在过去的40年里，星系和星系团的非随机星团引起了越来越多的关注。概述了用于区分观测分布和泊松分布(即随机的、统计上均匀的分布)的数学检验和准则。回顾了星系和星系团在从0.1MPC到至少100MPC的不同特征长度尺度A上支持(和反对)等级聚集的观测证据。讨论了星系谱的一些宇宙学含义和可能的起源。关键词：星系-星系团1.绪论2.亚星系团：成对和多重态(A 0.1MPC)3.小尺度星系团：群和小星系团(A1 MPC)4.统计学原理5.哑度指数和弥散-细分曲线6.相关技术和功率谱分析7.星系吸收效应.平均效应.涨落效应8.中尺度星系团：大星系团、云复合体和超星系团(A 10 MPC)9.丰富星系团的分布A.兹维基星表B.Abell星表10.大尺度星团和密度梯度(A 100 MPC)11.星系星系团和密度-半径关系12.星系团的光谱及其起源
The nonrandom clustering of galaxies and clusters of galaxies has attracted increasing attention in the past 40 years. The mathematical tests and criteria used to distinguish between an observed distribution and a Poisson, i.e., random, statistically uniform distribution, are outlined. The observational evidence for (and against) hierarchical clustering of galaxies and clusters on various characteristic length scales A from 0.1 Mpc to at least 100 Mpc, is reviewed. Some cosmological implications and possible origins of the clustering spectrum are discussed. Key words: galaxies - clusters of galaxies 1. Introduction 2.
