从图G的补图谱半径角度研究图的泛圈性.利用图的补图谱半径的界,讨论泛圈图存在的谱条件,证明了n阶图G,如果μ（G）≤（n-3）（1/2）,则图G是泛圈图.
從圖G的補圖譜半徑角度研究圖的汎圈性.利用圖的補圖譜半徑的界,討論汎圈圖存在的譜條件,證明瞭n階圖G,如果μ（G）≤（n-3）（1/2）,則圖G是汎圈圖.

In this paper, some spectral conditions we studied pancyclic of a graph from the spectral radius of a graph G. for the existence of pancyclic graph by using bounds on spectral We discussed radius of the complement of a graph, and show that if G was a graph of order n withμ（G）≤（n-3）（1/2）, then G was a pancyclic graph.
