According to the RFLP analysis and phylogeographic pattern, combined the radiation record of A. pernyi, it was inferred that the 12 cultivars used might origin from two different maternal ancestors, one from Henan province and the other from Shandong.

根据对12个柞蚕品种的线粒体AT富集区和tRNA〓基因序列的模拟酶切和种内系统发育分析结果，结合柞蚕种的传播历史记载，本文推测所分析的12个品种可能有2个母系来源：一个来源于山东，一个来源于河南。

Through the traditional physiological and biochemical method, together with the 16SrDNA sequence homology and phylogenetic analysis, the strains were identified. The result shows they belong to the genus photobacterium, but they differ from any species of this genus in some characteristic which suggests they might be new species, and their taxonomic placement needs more information on genes level.

对两株菌进行鉴定，分析其生理生化特征和16SrDNA产物序列，确定这两株菌均属于发光杆菌属，但是和该属的各种还有一定差异，对其分类地位的最后确定还需进一步的系统发育学分析。

The potential functions of these genes were discussed on the basis of phylogenetic and expression pattern.

根据基因系统发育树和表达模式讨论了这些基因的功能。

Phylogenetic methods have been widely used to detect the evolution of influenza viruses.

系统发育分析方法被广泛应用于检测流感病毒的进化。

Molecular ecological methods may be used for phylogenetic analysis, genetic differentiation of populations, and identification of kinship.

利用分子生物学技术可以研究物种的系统发育、种群的遗传分化、个体的亲缘关系等。

Phylogenetic studies are needed to test this hypothesis.

系统发育研究被需要来测试这个假说。

The successive start-up of genome project in recent years has far-reaching impact on present phylogenetic studies.

生物基因组计划的相继启动对系统发育学研究的发展产生了深远影响。

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。
