摘　　要：用构造的方法给出了优美图T_(n)和1∧C_(4,n)的冠I(T_(n))和I(1∧C_(4,n))的优美标号,并证明了I(T_(n))和I(1∧C_(4,n))都是优美图.This paper uses the construction method to give the graceful labels of the crowns I(Tn) and I(1-∧C4,n) of the graceful graphs Tnand 1-∧C4,n,thus proving that both I(Tn) and I(1-∧C4,n) are graceful graphs.

关 键 词：优美图 优美标号 冠 梯子
