分群

We also examine the traditional agglomerative hierarchical clustering methods using the information of content to have a thorough comparison.

我们也检验传统用文章内容为资讯的聚合阶层式分群方法以更全面比较其中差异。

While statistical techniques have been optimized to improve model accuracy, less focus has been given to the question: How does the autecology of a single species affect model quality We compare a direct modelling approach versus a cumulative modelling approach for predicting plant species richness, where the latter gives more weight to the ecology of functional species groups.

当统计技术有效改善模式的正确性时，较少注意已存在的问题：个体生物学中，单一物种是否会影响模式特性我们比较直接模式与渐增模式在植物物种丰富度的准确性，后者的权重以生态功能物种分群。

Multiple sequence alignment and phylogenetic analysis of CVX-NTU and other completely sequenced potexviruses demonstrated that CVX-NTU has a close relationship with potexviruses infecting plants in the family Cactaceae.

将CVX-NTU病毒分离株各个ORF与其它已知序列的同属病毒作胺基酸序列比对及类缘分析，结果显示感染仙人掌科的potexvirus都属同一个分群中，显示彼此的类缘关系较密切。

However, few other matrilineal splits from the first 100,000 years of the species's history have survived to the present day.

然而，10万年之前人类历史上的其他的母系分群几乎没有存活至今的。

Besides, it is consistent with the asymmetrical gene flow from monogynous to polygynous populations through males in monogyne..Therefore, the cuticular chemicals can not be cluster well between monogynous and polygynous ants, and the variance of chemicals of the latter is higher than those of the former.

由於这些化学物质的合成受到遗传影响，这种现象显示两个涵义，第一个是单蚁后社会型的工蚁对其他蚁后有强烈的排他性而造成的选汰压力导致其遗传结构上较为均质，另一个涵义显示单蚁后社会型的遗传组成可藉由雄蚁将其基因带入多蚁后社会型的遗传组成，但反之则不然；因此二者之间无法分群，且后者的遗传变异较前者为大。

Besides, the advantages of both hierarchical clustering algorithm and partitional clustering algorithm are also incorporated into the ICA clustering algorithm.

此外，双方优势的阶层式聚类法和分割式聚类法也纳入区间式竞争分群演算法。

The cells are belieed to be made up of at least two phenotypically distinct populations.

这些细胞至少有2种不同的分群，彼此形态各异。

The senior author, YIN Wen\|Ying suggested a new consideration on the higher taxa systematic of the Class Protura at the 20th International Congress of Entomology at Firenze, Italy in 1996. Only a brief abstract of this suggestion was published in the Proceedings of the Congress.

1996年第 2 0届国际昆虫学大会上，尹文英根据多年研究的新发现提出了原尾纲Protura分为 3目 10科的新建议，仅刊登在该次会议的论文摘要中，至今尚未能详细阐述重新分群的重要特征和分析。

Protura ; regrouping ; characters ; cladistic analysis.

Three primer pairs located in psbA~trnK, psbB~psbH and trnR-ACG~trnN-GUU regions were applied in phylogenetic analysis according to Maximum parsimony and Neighbor-joining methods. The consistent results between the phylogenetic analysis and taxonomy indicated the application potential of the three primer pairs in phylogenetic analysis and species identification. However, due to no sequence variation observed in amplified regions between two vegetable soybean varieties (KS5 and KS8), two cowpea subspecies (Vigna unguiculata ssp. cylindrica and Vigna unguiculata ssp. sesquipedalis), and among three rice varieties (TNG67, TK9, and TCS10), the three primer pairs are not effective in identifying variation within species.

选择其中三组引子对(基因体位置为psbA~trnK、psbB~psbH及trnR-ACG~trnN-GUU)增幅片段之序列进行亲缘分析，以最大简约法及邻接法之分群结果皆与目前植物分类相符，故三组引子对在物种间亲缘关系分析及物种鉴定上都有不错的效果，位於psbA~trnK及psbB~psbH之引子对效果尤佳，但是三组引子对在物种内变异的辨识效果不甚理想，在两个毛豆品种间(高雄5号与高雄8号)、两个豇豆亚种间及三个水稻品种间(台农67号、台稉9号与台中秈10号)的增幅片段没有明显差异存在。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
