    1998年,Estrada等人在Randi＇c指数的基础上进一步提出了原子键连通性指数,简称ABC指数.该指数已被用来研究烷烃的稳定性以及环烷烃的应变能等.该文给出了双圈图ABC指数的上界并确定了具有最大ABC指数的双圈图.

    In order to take factors into account but at the same time to keep the spirit of Randi c＇ index,Estrada et al.proposed a new index in 1998,known as the atom-bond connectivity（ABC） index.The ABC index has been applied up to now to the study of the stability of alkanes and the strain energy of cycloalkanes.In this paper,we give the sharp upper bound on ABC index of bicyclic graphs.
