拓展了目前关于星与低阶图的笛卡儿积交叉数的某些结论,确定了1个特殊6-阶图与星K1,n的笛卡儿积交叉数为z(6,n)+4n,并给出了1个有在K2,4,n中加入2条边分别联结K2,4,n中2对,1+2度点得到的1个特殊图类Hn的交叉数.%There are several known exact results on the crossing numbers of Cartesian products of stars with "small" graphs. In this paper we extend these results to the cartesian products of a specific 6-vertex with the star K1,n and determine its crossing number is z(6, n)+4n. In addition we give the crossing number of the graph Hn obtained by adding 2 edges to the graphin K2,4,n such a way that these new edges respectively join a pair of vertices of degree n+2 of the graph K2,4,n.
