利用从GenBank中下载的22个海豹科动物的ND4L基因序列的系统进化分析表明，海豹科动物分为南半球和北半球两大类群，斑海豹与港海豹为北半球种类，亲缘关系最近。从46个辽东湾斑海豹线粒体DNA控制区和苏氨酸及脯氨酸tRNA基因717bp片段的测序，得到17个单倍型。

SSRs are very suitable for research on genetic diversity and phylogenetic relationship since they are more reliable, co-dominant in heritance large number of alleles per locus, and abundance in genomes.

From the RAPD analysis data, the band similarity rates and average band similarity rates between two individuals in the sampling population, average band allele frequencies, average band heterozygosis degree, and the Shannon genetic diversity index were calculated to perform the cluster analysis of heterozygosis arithmetic averages and construct the phylogenetic tree.

根据RAPD结果分别计算了两两个体间的带纹相似率、平均带纹相似率、带纹的平均等位基因频率和平均带纹杂合度及遗传多样性指数，作亲缘关系的类平均聚类并绘制了相关关系聚类图。

They shared the highest homology to "world-B" group isolates in Brassica pathotype (between 91.8% and 100%). Phylogenetic analysis based on the CP gene sequences of TuMV strains or isolates showed that these 6 TuMV isolates from Shandong belonged to "world-B" group.

所得6个分离物的CP基因的核苷酸序列同源性较高，在97.0%～99.4%之间，系统进化分析表明：它们与Brassica致病型分离物中的world-B组分离物的同源性最高（91.8%～100%），亲缘关系最近，从而从分子水平上将TuMV山东分离物划分为world-B组。

The molecular markers have been applied in phylogenetic analyses, construction of genetic linkage map and identification of cultivars in roses.

分子标记已广泛应用于月季亲缘关系分析、遗传图谱的构建和品种的鉴定。

The phylogenetic trees revealed the GD3 strain was a intergrade virus strain evoluated from classical PRRV CH-1a strain to the PRRSV JXA1 and HUN4 mutant strains indicated by 97.1 %, and 97.2 % nucleotide homology with JXA1 and HuN4 strain, 94.9% nucleotide homology with CH-1a strain.

序列分析结果表明，GD3株在分子遗传演化上介于PRRSV变异毒株(HuN4 株、JXA1株)和CH-1a之间，与HuN4和JXA1之间的相似性为97.1 %和97.2 %；与CH-1a的核苷酸相似性为94.9 %。

Avian vocalization,which is a tool of intraspecific communication and interpecific and a kind of mechanism of intraspecific identification,is widely used in the phylogenetic studies.

鸟类的鸣声作为同种个体间的一种通讯方式及种内和种间的识别机制早已被广泛的应用在系统学的研究中。

Apparently, the results is determined extremely by theoretical algorithm. In 147 zinc-finger-containing genes, 50nt identity sequences were extracted. The results hint that 15 genes may related to block evolution. we analyzed the phylogenetic map of these 15 genes by uncorrected distance, Jukes Cantor distance, Tamura distance, Tajima-Nei distance, Jin-Nei distance or Kimura distance correction, but we found no satisfied result according to the block exchange pattern mentioned before. Introducing Bootstrap test to assistant correction, an comparatively perfect map was drown by Neighbor Joining method.

以147个含锌指基因为模板，我们搜索了其中的50nt一致序列作为板块式进化的核心，获得15个相关基因，应用无校正距离、Jukes Cantor校正距离、Tamura校正距离、Tajima-Nei校正距离、Jin-Nei校正距离和Kimura校正距离等分析了他们之间的进化关系，结果与已知的板块交换模式吻合度较差，引入靴带检验对Jukes Cantor校正距离结果进行统计学校正，并重新用Neighbor Joining方法绘制进化图，结果可靠性大大提高。

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。
