| 摘 要： | 通过依次给具有二分优美标号的树的每个顶点连续添加两次悬挂点, 运用拆分的方式, 有效证明了一类超级对虾树S(P2m)(其中m为任意正整数)为强优美树, 该方法称为悬挂拆分法.

| Abstract: | Adding suspension points to those trees having set ordered graceful labellings two times, and then using a split approach, we proved that a class of the super lobster trees S(P2m) were strongly graceful tree, where m is an arbitrary positive integer. This method is called the suspension split method. |
