摘　　要：利用距离正则图的交叉表及性质对k=10,a1=1的距离正则图的参数进行了讨论,可对其得到的结论进行分类。By mean of intersection diagrams, properties of distance-regular graphs and the known conclusions of distance-regular graphs in this thesis, we discuss intersection numbers of distance-regular graphs. Using the conclusion of this thesis, we can give a classification of distance-regular graph of ar＋2 = 4.
