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(jì)算圖的交叉數(shù)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(wèn)題上的一個(gè)最重要的進(jìn)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(duì)頂點(diǎn)數(shù)較小的正則圖的交叉數(shù)進(jìn)行研究,計(jì)算出n 16的三正則圖和n 12的四正則圖的交叉數(shù),以及n 30的三正則圖和n 19的四正則圖的最大交叉數(shù)的下限( n為圖的頂點(diǎn)個(gè)數(shù)) ,根據(jù)計(jì)算結(jié)果提出關(guān)于正則圖最大交叉數(shù)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(jié)核ccn的數(shù)濃度采用超幾何函數(shù)表示;云水向雨水的自動(dòng)轉(zhuǎn)換過(guò)程采用grabowski ( 1999 )的公式,考慮了云滴譜的特征和發(fā)展變化對(duì)該過(guò)程的影響,而不是采用原方案給定閾值的方法描述該過(guò)程;對(duì)連續(xù)碰并方程不再將粒子落速差作為常量提出積分號(hào)外,而是直接作為粒子直徑函數(shù)在積分號(hào)內(nèi)求解,這樣處理可以回避使用粒子群的平均落速帶來(lái)的誤差;增加了霰和雪、霰和冰晶的碰并微物理過(guò)程。
