摘要
本文利用“特征数”对应所有n位数在重排求差变换T下的象,且将“共轭”的特征数结合成组；构造出N_n在变换T下的简化有向图。从而得到比文[1]更多的关于黑洞数的结果。
In this paper .using characteristic immbers as codes of images of decimal integers with iidigits by rearrangement -diviation transformation ,setting all conjugate characteristic numbers to same group ,we constract the Simplified Digraphs and obtain more results about tblack -hole numbers than [1]
