    如果G是连通的并且G的边数是n+1,那么n阶图G叫做双圈图.设B(n)是所有的阶为n的双圈图构成的集合.本文给出了B(n)(n≥9)中前三大的邻接谱半径以及它们对应的图.

    A graph G of order n is called a bicyclic graph if G is connected and the number of edges of G is n + 1. Let B(n) be the set of all bicyclic graphs on n vertices. In this paper,the first three largest spectral radii in the class B(n) (n≥9) together with the corresponding graphs are given.
