摘要 讨论2n个优美二分图与一条通路并的优美性,得到如下结论:设二分图G=(X,Y,E)优美,优美标号为θ,边数为q,a=max{k|0<k<q,k≠(v),v∈V(G)},b=min{k|0<k<q,k≠(v),v∈V(G)},h=min{q-a,b},pm为m长简单路.(1)当m=2n-1或m≥2n+h时,(2n)G∪pm是优美的.(2)若q为奇数,则图(q+2)G是优美的. The present paper deals with the gracefulness of unconnected graph,and proves the following results:let G is a graceful bipartite graph with q edges,gracefu labeling of G is θ,a=max{k|0kq,k≠θ(v),v∈V(G)},b=min{k|0kq,k≠θ(v),v∈V(G)},h=min{q-a,b},Pm is a path with m edges,(1) when m=2n-1 or m≥2n+h,then the graph(2n)G∪Pm be a graceful graph.(2) when q is odd,then(q+2)G be a graceful graph.
