利用CfA2南部星系的数据，研究了星系数分布的尺度特性。构造了两个星系星等为MB(0) 19:42和MB(0) 20:00的体积有限样本，并采用盒计数法计算了二阶至九阶矩。在5 ~ 27h1mpc的尺度上，矩表现出多重分形尺度。从标度指数来看，我们认为星系处于具有丝状密集区域的平面结构中。
The southern CfA2 galaxy data are used to investi- gate the scaling properties of the galaxy number distribution. We construct two volume-limited samples with galaxy magni- tudes MB(0) 19:42 and MB(0) 20:00, and calculate the second- to ninth-order moments with the box-counting method. On scales from 5 to 27 h 1 Mpc, the moments exhibit multi- fractal scalings. From the exponents of the scalings, we suggest that the galaxies lie in planar structures which have filamentary dense regions.
