Abstract: By applying determinant det2(A) in boolean algebra,the authors introduce the characteristic determinant det2(A) and discuss the relationship between the features of det2(A) and the cycle of directed graph.Based on the conclusions,the authors put forward some new features of directed H-graph and its new judgment criteria.

Key words: boolean determinant;characterisitic determinant of directed , digraph;judgment of directed H-graph
