The authors consider regular graphs as Cm,Kn and strongly regular graphs,for example,cocktail party graph,CP(k); a special class of Kneser graphs,KW2 and Johnson graphs:Cm,Kn J(W,2,1) with the method of matrix theory,the authors obtain some conclusions.

• 运用矩阵理论的方法；研究正则图Cm；Kn以及强正则图如鸡尾酒会图CP(k)；Kneser图KW2；Johnson图J(w；2；1)的强积图的秩；得到了许多结果.
