摘　　要：本文构造了两类非连通图U(F_(m_i,t)) from i=1 to n和U(F_(m_i,t)) from i=1 to n,并证明了这两类图是优美的,且也是交错的.The present paper defines two kinds of unconnected graphs of ^nUi=1 Fmi,t and ^nUi=1 Hmi,t Furthermore we have proved that the unconnected graphs of ^nUi=1 Fmi,t and ^nUi=1 Hmi,t are graceful ones and they are alternating ones.

关 键 词：图 非连通图 优美图 交错图
