查询词典 two pairs

Inthe paper, we study the relation of pairs of lines and pairs of needles, and two results ofintegral formulas are gained. Thus, the geometric probability problem is solved. Also.we give a solution to the problem: pick two points randomly in a convex body K anddraw two lines passing through two points.

文章考虑了线偶与针偶的依附关系，得到了两个积分公式的结果，从而解决了这一问题，并得到了随机地在凸体K内任取两点，通过这两点任意投掷两直线，两直线的交点落入凸体K内的概率及其它的一些结果和推论。

Three primer pairs located in psbA~trnK, psbB~psbH and trnR-ACG~trnN-GUU regions were applied in phylogenetic analysis according to Maximum parsimony and Neighbor-joining methods. The consistent results between the phylogenetic analysis and taxonomy indicated the application potential of the three primer pairs in phylogenetic analysis and species identification. However, due to no sequence variation observed in amplified regions between two vegetable soybean varieties (KS5 and KS8), two cowpea subspecies (Vigna unguiculata ssp. cylindrica and Vigna unguiculata ssp. sesquipedalis), and among three rice varieties (TNG67, TK9, and TCS10), the three primer pairs are not effective in identifying variation within species.

选择其中三组引子对(基因体位置为psbA~trnK、psbB~psbH及trnR-ACG~trnN-GUU)增幅片段之序列进行亲缘分析，以最大简约法及邻接法之分群结果皆与目前植物分类相符，故三组引子对在物种间亲缘关系分析及物种鉴定上都有不错的效果，位於psbA~trnK及psbB~psbH之引子对效果尤佳，但是三组引子对在物种内变异的辨识效果不甚理想，在两个毛豆品种间(高雄5号与高雄8号)、两个豇豆亚种间及三个水稻品种间(台农67号、台稉9号与台中秈10号)的增幅片段没有明显差异存在。

以分析两对齿轮副构成的定轴轮系为非圆齿轮机构分析的起始点，本文首先分析了两对齿轮之间有相位角与无相位角两种安装情况下，定轴轮系的构成原理与轮系等价齿轮副的传动关系。

Methods Using the well-conserved regions of the DNA polymerase gene in human herpesviruses,we synthesized two pairs of primer,including one pair of primer designed to amplify herpes simplex virus type 1 and 2,Epstein-Barr virus and cytomegalovirus,another pair of primer to varicella-zoster virus and human herpesvirus 6 by PCR.

2 0 0 2年 1～ 12月浙江大学儿童医院在疱疹类病毒高度同源序列DNA多聚酶基因中设计两对通用引物，该引物能同时扩增单纯疱疹病毒Ⅰ型与Ⅱ型、爱泼斯坦—马尔病毒、人巨细胞病毒、水痘带状疱疹病毒和人类疱疹病毒 6型(HHV6) 6种病毒。

Two pairs of chutes and holes on the cleaning base and the brushes form the double chute swing mechanisms by the connection of an axis and cause the brush to cling to the wall surface to clean by the friction feedback, thus achieving effective cleaning when walking error occurs and the pipe section changes, furthermore, the larger the friction on the wall surface is, the larger the forward pressure on the wall surface is, therefore, the dirtier the wall surface is, the higher the cleaning efficiency is.

清扫底座与刷子夹上的两对滑槽和孔通过轴的连接形成双滑槽摆动机构，并通过摩擦力反馈使得刷子能够紧贴壁面进行清洗，从而在出现行走误差和管道截面变化时都能够有效清洗，并且壁面摩擦力越大刷子作用在壁面上的正压力越大，因此壁面越脏时清扫效率越高。
