Zhou Da · Harbin Gongcheng Daxue Xuebao/Journal of Harbin Engineering University · 2000
The paper presented a graceful label of the graph of the first category.Therefore,we came to the following conclusions:When dragonC n⊙P t,it is a graceful diagram.The nonconnection C 2k+1 ∪P k is a graceful graph.The bi_loop C 4m+1 C 4m+2 ,C 4m-1 C 4m+1 ,C 4n C 4m+3 ,C 4n C 4m are graceful graphs.
