摘要
本文主要给出了两类图的支撑树的计数公式,这两类图的支撑树的计数公式,几乎把目前所获得的特殊图的计数公式都作为它们的特例。另外附带地给出了几类图的支撑树的简便计数方法。
The enumeration formulars of two types of graphs are mainly given in this paper, the enumeration formulars of spanning-tree of the two types of graphs include almost all enumeration formulars of particular graphs obtained in the past as their special situations. The simple enumeration methods about the spanning-tree of several types of graphs are obtained.
