After analysis of multiple sequences alignment, phylogenetic tree and similarity of sequences, it was shown that Ac-ASP has similar relation with Am-ASP, and shared high homology with other Hymenopteran and Coleopteran. From above analysis, we firmly suggest Ac-ASP1 and Ac-ASP2 belong to OBPs family and Ac-ASP3 belong to CSPs family.

通过多序列联配、系统发育树及序列相似性分析，Ac-ASP除与西方蜜蜂Am-ASP亲缘关系较近(相似性达到80％以上)外，与其它膜翅目以及鞘翅目的OBPs及CSPs也有一定的亲缘关系(相似性达到30～60％)，且Ac-ASP1和Ac-ASP2应为OBPs，Ac-ASP3则应为CSPs； 4。

While the divergence of homologous genes from different species is in well congruent with phylogenetic relationship of those species.

不同物种的同一种基因的聚类关系能较好地反映物种间的系统发育关系。

将所得序列与各科鱼、蛙、鸡、牛、鼠、人等的β-肌动蛋白基因序列同源性分析显示，核苷酸序列具有68%~95%的相似性，氨基酸序列具有97%~100%相似性，显示该基因在生物进化过程中的保守；系统发育分析表明黄鳝β-肌动蛋白基因与罗非鱼的亲缘关系最近。

Objective To clone and express a new protein adenosine deaminase of Schistosoma japonicum.

目的 克隆和表达日本血吸虫腺苷脱氨酶编码基因，分析该基因的系统发育及预测其编码蛋白的空间结构。

Evolution and phylogeny are a factual system based upon the temporal order framework of fossils, which by no means can be deducible solely by any data analysis.

进化和系统发育是以化石的时序框架为基础的事实体系，而绝不可能单独通过任何数据分析就可推测。

The dendrogram from RAPD markers supported that Shantao was in an independent group. 5. Core germplasm in each deme was put forward and listed as Liemage, Haluhong, Bailey, Akelawa in rootstock group; Hongchongban, Shouxintao, etc.

采用ITS序列重建系统发育树，陕甘山桃和山桃为并行分支，各自成为独立一组，位于桃、新疆桃，光核桃、甘肃桃的基部。

Direct sequencing of DNA amplified by PCR was used with the primers designed according to the sequence of control region and the neighbor region. Sequences were analyzed and compared base on Sequencing Analysis 3.4 and Seq/Ede software. DP of mtDNA in Yao ethnic group was calculated. MAGA2 software was also employed to analyze the genetic distance between samples and construct the phylogenentic tree.

以南方民族瑶族为研究对象，根据mtDNA控制区及周围区域的序列设计引物，用PCR产物直接测序对105份无关瑶族样本mtDNA控制区进行了测序，通过Sequencing Analysis 3.4和Seq/Ede软件分析比对，得到的序列结果，计算瑶族mtDNA单倍型的识别率，并应用MEGA 2软件对数据做进化距离分析，构建系统发育树。

The middle and small breed dogs were clustered at first; German Sheepdog, Swedish Elkhound, and Black Russian Terrier were clustered into one group, and the Tibetan Mastiff, Old English Sheepdog, Leonberger, and Saint Bernard were clustered in another group.

本文根据家犬线粒体基因组DNA序列设计引物，获得了2，525bp的藏獒线粒体DNA序列（包括细胞色素b、tRNA-Thr、tRNA-Pro和控制区全序列），并以灰狼、郊狼作为外类群对藏獒、12个家犬品种进行了系统发育分析。

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。
