| Abstract: | It mainly introduced the relations between degree sequence of tree and the spectra of its line graph in this paper. Firstly, the relations between the degree sequence of the centrally symmetric especial tree and eiqenvalue of maximum of its line graph were obtained, then the relations between degree sequence of general tree and eiqenvalue of maximum of its line graph were got by using of the centrally symmetric tree. |

| Keywords: | centrally symmetric tree clique number diameter |
