摘要
证明了三角蛇图、梳子图都是边幻图。给出了简单连通图是边幻图的一个充分条件。对满足一定条件的边幻图从规模和种类两个方面进行了扩张。
We prove several classes of special graphs are edge-magic graphs,such as:triangular snake,comb tree and dragonfly tree.Theorem 4 gives a sufficient condition about the edge-magic labeling of connectedsimple graphs.Theorem 5 and 6 can be used to generalize largerer and more complicatied edge-magic graphs.
