关于皇冠Q_n(2|n)的调和性

On the Harmonicity of the Crown Q_n (2| n)

文章研究了皇冠Qn(2|n)的调和性,给出了关于Qn(2|n)调和的必要条件,从而确定了一类可行的调和设计方案．并验证了当n=4,6,8,10,12,14,16,18时,Qn(2|n)为调和图．

This paper has studied the narmonicity of the Crown Qn（2｜n）, and given the necessary condition of the harmonicity for the Crown Qn（2｜n）. Thus, a kind of feasible scheme about har- monious labeling of Crown Qn（2｜n） is given and proved the harmonicity of the Crown Qn（2｜n） when n =4,6,8,10,12,14,16,18.
