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(P_(2m))(其中m为任意正整数)为强优美树,该方法称为悬挂-拆分法.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（ P_（2m）） were strongly graceful tree,where m is an arbitrary positive integer. This method is called the suspension-split method.

关 键 词：树 强优美标号 完美匹配
