| Abstract: | The constitution of the equivalent directed graph D(G) of undirected graph G is discussed.By using the Boolean determinant det2(A) and it’s nature,as well as the criterion and methods of judging Boolean determinant for the directed H-graph,the new criterion and methods of judging Boolean determinant for the undirected H-graph are obtained. |

| Keywords: | Boolean determinant undirected graph equivalent directed graph character determinant ofundirected graph criterion of undirected graph. |
