摘　　要：本文研究了两类连通双圈图的最大特征值,得出了随着n的增大,双圈图Sn(3,3)和θn(3,3)的最大特征值也随之增大;同时给出了n≥5在的条件下,Sn(3,3)和θn(3,3)的最大特征值的比较。This paper studies the maximum eigenvalues of two types of connected bicyclic graphs, and finds that as n increases, the maximum eigenvalues of bicyclic graphs Sn(3,3) and θn(3,3) also increase;at the same time, it also gives a comparison of the maximum eigenvalues of Sn(3,3) and θn(3,3) under the condition of n≥5.

关 键 词：双圈图 特征值
