系统发育

The ability of cultural evolution to maintain intergroup diversity is what allows for the study of cultural phylogenetics.

文化进化保持群组间多样性的能力，为文化的系统发育研究提供了可能性。

All 13 strains can agglutinate the red blood cell of chicken and human O type. However, their ability of agglutinating the erythrocytes of swine, horse, cow, rabbit and guinea pig were variable.

为了分析分离毒株的流行病学来源及它们之间的相互关系，我们对13 株F 基因1-374bp 的片段进行同源性分析比较并绘制了系统发育树。

One method of inferring phylogeny is to pinpoint primitive as opposed to advanced characters.

推断系统发育的一个方法是准确查明那些与进化性状相对的原始性状。

This paper presents a review of the main methods of the polyphasie taxonomy system and the phylogeny of rhizobia.

文中主要阐述了根瘤菌多相分类体系中的主要方法及现代根瘤菌系统发育地位的研究和进展。

Methods The spiroplasma morphology was examined by dark-field microscope and transmission electron microscopy. The biological characteristics of the spiroplasmas were investigated by using conventional culture-dependent method and phylogenetic analysis based on 16S rRNA gene and ITS (16~23S rDNA intergenic space) sequence comparisons.

常规螺原体分离、培养方法，应用暗视野显微镜和透射电子显微镜观察螺原体形态，根据16S rDNA和ITS序列构建系统发育树研究螺原体分离菌株可能的分类地位。

Amino acid sequences of l ysin in 28 known abalones are analyzed by Cluswtal to find their comparability and these abalones cladogram.

以鲍精子识别蛋白为分子标记，通过对比已知的28种鲍lysin的氨基酸序列来研究鲍的系统发育特征。

On the basis of introduction of the phylogenetic relationship and gene flow between biotypes Q and B of B.

在介绍烟粉虱Q型与B型系统发育关系以及基因交流的基础上，着重论述这两种生物型的种群动态及其影响因子的研究进展，以期揭示烟粉虱Q型与B型的成功入侵机制，并为其控制提供依据。

在介绍烟粉虱Q型与B型系统发育关系以及基因交流的基础上，着重论述这两种生物型的种群动态及其影响因子的研究进展，以期揭示烟粉虱Q型与B型的成功入侵机制，并为其控制提供依据。

The constructed phylogenetic tree revealed that the relationship between T.saginata asiatica and T.saginata is closer, both are distant relative to T.solium and other species of cestodes.

系统发育树状图显示，牛带绦虫亚洲亚种和牛带绦虫最为接近，远离猪带绦虫及其他绦虫。

Numerical classification and cladistic analysis were new ways in phylogenetics.

数值分类和支序分类是系统发育分析的两种新方法。

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。
