The average panmictic heterozygosity ( hs = 0.3037 ± 0.0058) in the Gongliu population was the highest, followed by the Huocheng population.

巩留群体、新源群体、霍城群体和裕民群体分别扩增了180、169、178和165条多态性带，巩留群体的随机交配杂合度（ hs = 0.3037 ± 0.0058）最高，其次为霍城群体。

Together with the cited sequences of other species (cattle, zebu cattle and buffalo), the molecular phylogenetic tree was therefore built to probe phylogenetic relationship between Bovine subfamilies, Total 5 variation sites were examined and two types of mutation, transition and transversion, were observed, with the overage percentage of nucleotide variation of 1.66%. It demonstrated the poverty of polymorphism at exon 5 of GH gene of three bovine species. There was only one missense mutation out of 5 mutation sites which led to the shift between leu and val amino.

结果表明，在雷琼牛、巴州牦牛和巴州蒙古牛中共检测到5个变异位点，核苷酸取代方式仅有转换和颠换，核苷酸平均突变率仅为1.66%，说明这3个牛种GH基因外显子5多态性较为贫乏；5个变异位点中仅有1个为错义突变，导致亮氨酸和缬氨酸的转换，但该突变在牛种中分布有差异。

By use of 90 individuals DNA from Gold Queen maize population, 6 inbred lines DNA, and 15 pair SSR primers, the effect of 4 kinds of DNA sample treatments of the individual DNA sample, the mixed DNA sample with 3 individuals, with 10 individuals, and with 15 individuals for the genetic diversity in the same population were compared and analyzed.

以金皇后玉米群体90个单株DNA和6个自交系DNA为供试材料，利用15对SSR引物，比较了同一群体 4种DNA样品处理(单株DNA样品、3个单株混合DNA样品、10个单株混合DNA样品、15个单株混合DNA样品)的SSR遗传多态性。

Methods Allele Specific polymerase chain reaction and Confronting Two-pair primers-PCR techniques were used to determine β_2-AR genetic polymorphisms in 42 patients with asthma,which were treated in The Affiliated Hospital of Inner Mongolia Medical College from 2004 July to 2005 September and 30 healthy controls.

方法对2004年7月至2005年9月内蒙古医学院附属医院收治的42例支气管哮喘患者和30名健康者采用等位基因特异性聚合酶链反应和两对相对引物PCR法(confronting two-pair primers，PCR-CTPP)进行β2-AR基因多态性分析。

In this study, we explored the relationship between the alpha2-HS glycoprotein gene and bone size variation at the spine and hip in a Chinese population.

本研究目的为检测中国人群中α2-HS糖蛋白基因多态性和腰椎及髋部骨大小变异之间的关联。

Methods DNAs from Candida species were amplified by PCR,and the amplicon was assayed by single-strand conformational polymorphism.

以聚合酶链反应对多种念珠菌进行扩增，而后采用单链构象多态性技术对6种念珠菌的扩增产物进行分析。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
