| Abstract: | 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. |
