摘要 介绍了κ-test算法基本原理,并将此算法运用于近邻星系团系统A399/A401。κ-test算法对该系统中215颗星系空间分布的成团现象进行了判定,证实确是真正物理意义上的成团。 The basic principal of the κ-test algorithm was presented and applied to a nearby pair of galaxy clusters A399/A401.The conglobation phenomenon of the spatial distribution for 215 galaxies in this system are determined by the κ-test algorithm,and as a result,it is found to be a real physical sense of conglobation.
