Abstract：The BC-subtree number index of graphs can reflect the important topological and structural characteristics of graphs,which is of great significance to prediction of new molecular properties,and discovery of new materials,new drugs. Based on the generating function and structure analysis in this paper,the BC-subtree generating function of book graphs is presented,and its asymptotic characteristics of BC subtree density is studied. This study provides a new perspective and method for further exploring the structural characteristics of complex circle graphs and important nanomolecules.
