宇宙大尺度分形结构的上限

On the Upper Cut-Off of the Large Scale Fractal Structure in the Universe

本文给出了用几种达到不同极限星等的星系表确定宇宙分形结构上限截止尺度的公式.利用Zwicky星系表、Shane-Wirtanen星系表和Jagellonian天区的星系表的数据,可以估计这一截止尺度R_c至少为60—70Mpc,且R_c随着自相似分布所占比例f的减小而增大,或可大到约270Mpc的尺度.

A formula used to determine the upper cut off Rc of the fractal structure of the Universe is given by analysis of different apparent magnitude limited catalogues. Using the data of the Zwicky, Lick and Jagellonian catalogues, the upper cut-off Rc can be estimated to be at least 60-70 Mpc. The value of Rc increases with decrease of the ratio of the self-similar distribution component to the random distribution component and it may extend to 270 Mpc.
