Using the algorithm ccn ( calculate crossing number ) invented by us , we investigate the crossing numbers of all graphs for n < 9 利用我們研制的計算圖的交叉數的算法ccn ( calculatecrossingnumber ) ,本文對n 9的所有圖的交叉數進行了研究。
Using the algorithm ccn ( calculate crossing number ) , this article researches on the relation between the crossing number and girth of the 3 - regular graphs 利用計算交叉數的算法ccn ( calculatecrossingnumber ) ,本文對三正則圖的交叉數與圍長的關系進行了深入的研究。
In this article , a algorithm ccn ( calculate crossing number ) is put forward to study the crossing number . it is a very important development in graph planarity issue after planarity - determinant algorithm and embedding algorithm 本文首次給出了較好的計算圖的交叉數算法ccn ( calculatecrossingnumber ) ,這是繼圖平面性判定算法,二連通圖的平面嵌入算法之后在圖的平面性問題上的一個最重要的進展。
By the algorithm ccn , we investigate the crossing numbers of regular graphs with small order . we get the crossing numbers of 3 - regular graphs for n < 16 and 4 - regular graphs for n < 12 , and the lower bounds of the maximum crossing numbers of 3 - regular graphs for n < 30 and 4 - regular graphs for n < 19 , where n is the order of graphs . according to the result , we put forward the conjecture about the maximum crossing numbers of regular graphs 本文還利用算法ccn ( calculatecrossingnumber )對頂點數較小的正則圖的交叉數進行研究,計算出n 16的三正則圖和n 12的四正則圖的交叉數,以及n 30的三正則圖和n 19的四正則圖的最大交叉數的下限( n為圖的頂點個數) ,根據計算結果提出關于正則圖最大交叉數的猜想。
The influence of the cloud droplet spectrum character and the spectrum growth and change is considered , which does not use a cut - off value for conversion from cloud water into rain water process . in the continuous coalescence equation , the particles fall velocity difference is not moved out from the integral , but is integrated in the equation as the function of diameter d to avoid the error of using particles average fall velocity . in the new scheme , generation rate of graupel due to the collection of snow by graupel and the collection of cloud ice by graupel are included 云中凝結核ccn的數濃度采用超幾何函數表示;云水向雨水的自動轉換過程采用grabowski ( 1999 )的公式,考慮了云滴譜的特征和發展變化對該過程的影響,而不是采用原方案給定閾值的方法描述該過程;對連續碰并方程不再將粒子落速差作為常量提出積分號外,而是直接作為粒子直徑函數在積分號內求解,這樣處理可以回避使用粒子群的平均落速帶來的誤差;增加了霰和雪、霰和冰晶的碰并微物理過程。
