摘　　要：我们知道轮Wn及齿轮图都是优美图.马克杰等在文[1]中已证明了轮Wn和齿_n轮都是优美图.本文将证明_n是k-优美图,并证明了当n≡0(mod2)时L_n也是k-优美图.We know weel and wheel are graceful graphs. Ma Ke Jie ect. have proved weel and wheel are graceful graph[1].In this paper,we will prove wheel is k- graceful graph and L_n is k- graceful graph when n ≡ 0(mod2) too.
