讨论了非连通图 I(Km,n )∪ G的优美性,给出了非连通图 I(Km,n )∪ G是优美图的一个充分条件:m,n 为任意自然数(2≤ m <n +2),非连通图 I(Km,n )∪ Gk+n+1是优美图。
討論瞭非連通圖 I(Km,n )∪ G的優美性,給齣瞭非連通圖 I(Km,n )∪ G是優美圖的一箇充分條件:m,n 為任意自然數(2≤ m <n +2),非連通圖 I(Km,n )∪ Gk+n+1是優美圖。

The gracefulness of the unconnected graph I(Km,n )∪G is discussed.One sufficient condition about determining the gracefulness of unconnected graph I(Km,n )∪G is obtained.For arbitrary positive integer m,n (2≤m <n +2),if there exists a balanced labeling of graph G,the critical value of the balanced of graph G is k and k +n +1 is the missing value of the balanced labeling of graph G,then the unconnected graph I(Km,n )∪G is a graceful graph.
