Furthermore, Ptychidio distinctly differed in osteological characters from other genera of Labeoninae, so it wasn't chosen as taxon of ingroup in phylogeny of Labeoninae. And Ptychidio's phylogenetic status can be ascertained only if more taxons of Cyprinidae be chosen and phylogeny of Cyprininae be solved in further research and molecular research.

此外，在特征分析时发现，卷口鱼属同野鲮亚科其它属的骨骼特征相差甚远，所以在分支系统学分析时没有被选择，有关其分类地位的确立，有待于今后在鲤科分支系统学研究中和分子生物学资料的研究中解决。

Baimatuoensis and Cloudina respectively imply that phosphatization of microbes was taxon-specific, and may due to the discrepancy of wall structures. The multi-walled S. levis with smooth outermost surface may be closely related to polychaete tubes with many organic laminae.

在共生的Sinotubulites baimatuoensis和Cloudina壳壁上，极少或完全不存在这些磷酸盐化组构表明微生物的磷酸盐化作用具有专属性，可能由壳壁微结构所决定，具多层状壁的S.levis可能与具许多有机质纹层的多毛类壳壁关系密切。

A taxon is any taxonomic grouping, such as a phylum , a family or a species

During ovulation the serosa wall is the thinnest. This study provides theoretical evidence for the taxon and artificial reproduction of Rana spinosa .

本实验的目的旨在为探讨棘胸蛙的分类学地位和棘胸蛙的人工繁殖性能等提供理论依据。

Especially,the subbranch of enterobacteriaceace made again four small branches as genus taxon.This tree also shows that bacilliform bacterium is distinct from each other in the NJ and MP trees.After all species on the tree are merged,the topological configuration of the unrooted tree of 16S gene is closed to that of the host range unrooted tree.However,the position of bacillus is greatly changed on both the unrooted trees.

将16S DNA的NJ树隐去所有的种，以属为单位所得到的以分枝形式的无根树在拓扑结构上与菌群分布含量所构建的无根树相近，但芽孢杆菌在两种无根树的位置中有较大的差异。

The results demonstrated closer relationship between the two species, in accordance with those from morphological classification. That is to say, the taxon of Helice is divided into two subgenera, Helicana H. japonica and H.

由于仿厚蟹亚属和厚蟹亚属的蟹类在外形上的差异较大，而且本研究的分子数据也表明二者之间存在着很大的遗传差异，因此，建议将此2亚属提升为属。

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。
