摘　　要：讨论了无向图G的等价有向图D(G)的构成,并利用布尔行列式det2(A)和det2(A)的性质,以及有向H-图的布尔行列式的判定方法和判定准则,给出了无向H-图的新特性和新判定准则.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 determi- nant for the undirected H-graph are obtained.

关 键 词：布尔行列式 无向图 等价有向图 无向图特征行列式 无向H-图判定准则
