摘　　要：如果任意与图G有相同Tutte多项式的图都同构于图G,那么,称图G是满足Tutte唯一性的,简称为T-唯一的.本论文研究了梯图的线图的T-唯一性.A graph G satisfies uniqueness of Tutte polynomial, Tutte - unique for short, if any other graph having the same Tutte polynomial as G is isomorphic to G. The Tutte - uniqueness of line graphs of ladders is studied in this paper.

关 键 词：Tutte多项式 线图 Tutte唯一性 梯形图
