Based on the complete sequences of the mitochondrial 12S rRNA and Cyt b genes, and the combined sequences of the two genes, the phylogenetic relationships among all extant zokors except the Siberian zokor (M. myospalax) and the Smith's zokor .

根据线粒体12S rRNA基因和Cyt b基因全序列以及合并的序列数据分别研究了鼢鼠亚科已知所有物种（除阿尔泰鼢鼠Myospalax myospalax和斯氏鼢鼠M.smithi）的系统发生关系。

Motherboard is not sufficient and stable voltage and current, so the system re-start phenomenon occurred.

主板得不到足够而稳定的电压和电流，于是系统发生了重启动现象。

Modern industrial civilization is colliding violently with our planet's ecological system.

现代工业文明与我们的星球生态系统发生了严重的冲突。

Back-pressure valve in the course of precautions are: 1, to void resonance with the system occurred.

背压阀在使用过程中应注意的事项有： 1、避免与系统发生共振。

The combination of a crystallographic plane and, within that plane, a crystallographic direction along which slip (i.e., dislocation motion) occurs.

滑移面和该面上一个滑移方向的组合称为一个滑移系，晶体滑移可以沿该系统发生。

Solutions should be deliverable in commercial, engineering and technical before detail design.

独立递交配电系统发生问题的处理方案。方案在商务和技术方面有可交付性。

As the product of the tumor (including ectopic hormone produced) or abnormal immune response (including cross-immunity, autoimmune and immune complex deposition, etc.) caused by endocrine, nerve, blood, digestion, bone joints, kidneys, skin lesions and other systems, causing corresponding clinical symptoms, known as paraneoplastic syndrome.

由于肿瘤的产物或异常免疫反应（包括交叉免疫、自身免疫和免疫复合物沉积等）引起内分泌、神经、造血、消化、骨关节、肾脏、皮肤等系统发生病变，引起相应的临床症状，称为副肿瘤综合征。

Grounding grid is essential to the safety of substation, however, the corrosion caused by earth may result in thinness even break of the grounding down-lead and horizontal equal-voltage conductor. This will lead to fault spread when grounding fault occurs, and will be dangerous to human and facilities.

接地网对变电站安全运行至关重要，但土壤的腐蚀可能使接地引线和水平均压导体变细甚至断裂，当系统发生接地故障时可能造成事故扩大，危及设备和人身安全。

Based on the result of PSI-BLAST search against GenBank Database, 38 microbial rhodopsin sequences were collected from archaea, eubacteria and eucarya. Two different phylogenetic methods were used to analyze their sequence alignment based on 7 transmembrane a-helice. The result of phylogenetic analysis shows that these microbial rhodopsins were divided into three clades.

对美国基因数据库进行PSI-BLAST搜索后，筛选了38条来自古细菌、细菌和真核生物的视紫红质蛋白质序列并进行了蛋白质结构和序列比对，并对比对结果用了邻接法和贝叶斯法进行了基于7个a螺旋跨膜结构的系统发生分析。

According to the proportion of taxa from archaea, eubacteria and eucarya in each clade, the division of three clades is consistent with three domains of life. However, every clade contains the rhodopsin from the other domain.

系统发生分析结果表明：这些微生物视紫红质分为3个进化分支，每个分支中按照古细菌，细菌和真核生物的多少可以归类为古细菌类、细菌类和真核生物类微生物视紫红质。

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。
