摘　　要：基于一些图参数得到了图G及其线图L(G)广义距离谱半径的上下界,并确定了极值图;然后计算了一些合成图的广义距离谱。The upper and lower bounds of the generalized distance spectral radius of G and of its line graph L(G)are obtained,based on some graph parameters,and the extremal graphs are determined.Then,the generalized distance spectrum of some composite graphs is calculated.
