In this experiment,nad4 and cox1 genetic variation of cestodes were firstly studied.Genetic variation and DNA polymorphism of mitochondria were carried out from mitochondrial gene.So the effective genetic markers were found which studied molecular taxonomy and Phylogenetic relationship of cestodes.This study have filled in the blank space of research that was related to China\'s cestodes mitochondrial genome research.

本试验首次对绦虫nad4和cox1基因的遗传变异情况进行研究，从线粒体基因的角度，开展绦虫线粒体遗传变异和DNA多态性方面的研究，找到了研究绦虫分子分类学、种群遗传关系有效的遗传标记，填补了我国寄生绦虫线粒体全基因组相关研究的空白。

遗传分类学是当前推断系统树的首选方法。

It makes sense of the geologic record, biogeography, parallels in embryonic development, biological homologies, vestigiality, cladistics and other fields, with unrivalled explanatory power; it has also become essential to applied sciences such as medicine and agriculture.

它以无与伦比的解释力，合理地解释了地质记录、生物地理学、胚胎发育的类似、生物同源性、退化遗迹、遗传分类学和其他的领域；它也已经成为应用科学的基本要素。

The dendrogram of clustering analysis showed that there were obvious difference between genus different species of Zanthoxlum.

结果显示，该方法可以有效地鉴别不同产地的花椒药材，且与经典形态分类学结果基本一致，是一种快速、简便、低耗的新型分析技术。

Numerical analysis indicated that B2817 was a species of genus Vibrio and shared a high homology with V. gazogenes. However, there were obvious differences between them in phenotypic and chemotaxonomic characterization. The result from this study indicates that B2817 is probably a novel species of Vibrio.

经多相分类学鉴定，发现B2817是弧菌属中一个种，与弧菌属中的产气弧菌Vibrio gazogenes亲缘关系最近，但两者在形态、生理生化特征、分子遗传等方面存在很大差异，故认为B2817可能是弧菌属的一株未被认识的新种。

This thesis attempt to provide some scientific evidence for the chemotaxonomy and medicine development of these genuses and to provide some of molecular basis for anticancer mechanisms of flavonoids.

本论文研究工作对上述的三个属的化学分类学及药用植物资源的合理应用、开发提供了一定的科学依据，同时对从分子水平研究黄酮类化合物抗肿瘤作用机制提供了一定的理论基础。

Based on the phylogenetic analysis, we interred that this was a result of a genome dulplication that occurred c.

我的&分子同僚&很聪明，他们在植物分类学领域从来不说自己是搞分类，也不敢说是研究植物系统发育重建分类系统的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
