In this paper, three correlative results are given : 1 ) the average crossing number of graph with n vertices and q edges can be signified approximately by quadratic equation of q. 2 ) the average crossing number of graphs with bigger girth is greater than that with smaller girth within given vertices and edges. 3 ) the average crossing number of r - regular graphs greater than that of non - regular graphs within given vertices and edges where n is odd or r < n / 2
並得出相關的規律： 1 ） n個頂點q條邊的單二連通分支圖的平均交叉數aac （ n ， q ）可近似地表示為q的二次多項式， 2 ）在給定頂點數n與邊數q的單二連通分支圖中圍長較大的圖的平均交叉數大於圍長較小的圖的平均交叉數， 3 ）在給定頂點數n與邊數q的單二連通分支圖中當n為奇數或r n / 2時， r正則圖的平均交叉數大於非r正則圖的平均交叉數。 -
