In general, the operation of insertion of removal of vertices of degree 2 does not affect the planarity of a graph . 一般地,插入或移去2次頂點運算,并不影響一個圖的平面性。
Nevertheless, it has been shown that side-chain planarity is important in conferring high adenyl cytokinin activity . 然而已經(jīng)證明,對于高的腺苷細(xì)胞激動素活性,側(cè)鏈的平面性很重要。
Planarity detection and embedding 平面性檢測和嵌入
Figure 5 . transfer efficiency of a solder paste related to aperture area ratio and its effect on reflowed bump co - planarity 圖5 ,錫高轉(zhuǎn)移的效率與孔面積比率及它對回流峰共面度的影響。
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(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題上的一個最重要的進(jìn)展。
On the basis of the deep analysis of the semiconductor device numerical analytical methods , using a pisces for dos as a kernel , we develop a software which can simulate the semiconductor devices under windows operation system . the software is programmed by mixed languages including visual c + + , fortran9o and matlab . so the problems such as mixed - language programming are solved and the interpolation algorithm on a triangle - partitioned planarity is realized 在對半導(dǎo)體器件數(shù)值分析方法和手段有深入分析的基礎(chǔ)上,以dos下的piscesii為內(nèi)核,綜合利用了vc + + , fortran90 , matlab等計算機語言,解決了混合語言編程的出現(xiàn)的如變量傳遞等多種難題,實現(xiàn)適用于三角形網(wǎng)格劃分二維空間的插值算法,開發(fā)了可以在windows操作系統(tǒng)下運行的一半導(dǎo)體器件模擬軟件,使得在windows下的器件模擬成為可能。
4 . the interaction between la3 + and mp - 11 would decrease in the intensity of the soret band and shift the band position , because of the strong coordination action of la3 + with o of the carboxyl group in the heme group and weak interaction of la3 + with o of the amido group in the peptide . the interaction also increases in the non - planarity of the heme group 由于la ~ ( 3 + )與血紅素上羧基氧o配位鍵合作用較強,而與多肽鏈上的酰氨氧o鍵合作用較弱,因此使mp - 11的soret帶吸收值下降,峰位紅移,血紅素環(huán)的非平面性增加。
A set of nonlinear equations of precise synthesis are established for special case according to co - planarity and equal distance conditions . by resultant elimination , 3 polynomial equations containing 3 variables are obtained . all of the groups of real solution within a certain value range are generated with computer graphic method 針對實現(xiàn)兩個函數(shù),每個函數(shù)四個精確點的rssr機構(gòu),通過結(jié)式消元法消元,得到三元高次多項式方程組,并采用計算機圖解法,在一定值范圍內(nèi)解出了方程組的全部實數(shù)解。
