就模型本身而言还需进一步的完善，最新的研究发现在许多种属的心肌细胞中Ik都有两种成分Ikr与Iks［4～6］，这无疑将使对Ik的理解更全面和完善。

After thecomplete genome extraction of the strain was performed, the genomic DNA was partiallydigested by restriction enzyme Sau3AⅠ, the DNA fragments from 1 to 5Kb was clonedinto prokaryote expression vector pET-28a-c, and transformed host bacteria. The resultsshowed that we succeeded in constructing the gene expression library of haemophilusparasuis serovar 5, which is fundamental for the study of advanced gene screening. Inaddition, primer design was performed based on haemophilus influenzae in this study. In addition, PCR was performed by using genomic DNA of haemophilus parasuisserovar 5 as the template. The results demonstrated that we obtained two neo-gene:23SrRNA gene(conserved gene belonging to the large-subunit of ribosome) and adenylatecyclase gene(encodes adenylate cyclase and participates in converting adenyl nucleosidetriphosphate to cyclic adenosine3",5"-monophosphate). Furthermore, the phylogeneticanalyses between the species was performed, and neighbor-joining tree was constructedbased on comparison of 23S rRNA gene sequences, so it was illuminated betweenHaemophilus parasuis and other species in molecular evolution relationship.

选择我国流行优势菌株副猪嗜血杆菌血清5型地方株为研究对象，提取细菌基因组DNA，用限制性内切酶Sau3AⅠ对基因组DNA进行部分酶切，回收大小为1～5Kb的DNA片段，将其连接入原核表达载体pET-28a-c，最后转化宿主菌，结果成功地构建了基因表达文库，为后续的基因筛选工作奠定基础；另外，本研究选择嗜血杆菌属的流感嗜血杆菌为参考对象进行引物的设计，以副猪嗜血杆菌血清5型地方菌株的基因组DNA为模板，进行PCR扩增反应，结果表明成功地获得两个新基因：23S rRNA基因(存在于核糖体大亚基中的保守性基因)和腺苷酸环化酶基因(负责将腺嘌呤核苷三磷酸转变为环腺苷酸)，并进一步做了不同物种之间的分子系统发育分析，构建了基于23S rRNA基因的邻接法系统发育树，阐明了副猪嗜血杆菌与其它菌种的分子进化关系。

The Antennal ultrastructures of the two closely related wasp species, Aprostocetus prolixus and Aprostocetus fukutai, were observed by scanning electron microscope. The types, numbers, morphological characteristics and distribution patterns of the antennal sensilla of the two species were described, and the differences between two sexes were compared too.

利用扫描电镜观察了同属的桑天牛卵啮小蜂和桑天牛长尾啮小蜂的触角感器，对这两种寄生蜂触角感器的种类、形态、数量及分布进行了描述，并对雌雄两性触角之间的差异做了比较。

Any of several weedy, chiefly biennial plants of the genus Arctium in the composite family, having pink or purplish flower heads surrounded by prickly bracts and forming a bur in fruit.

牛蒡任一种杂草，主要是菊科牛蒡属的两年生植物，开粉红色或略带紫色的花穗，并被带有多刺的苞所包围，形成果实中的刺果

The phylogenetic trees supported that Eriocaulaceae be treated as Eriocaulales because this family always been a nature independent group connected with other families. Eriocaulaceae grouped with Commelinaceae, which supported the close relationship and parallel evolution between the two families. Juncaceae was not close to Eriocaulaceae and more primitive. The relationship between Juncaceae and Cyperaceae was closer than that between Juncaceae and Poaceae. Among these families, Poaceae was the most primitive family and far from Eriocaulaceae. Also in Eriocaulaceae, Eriocaulon was supported to be more primitive.

从构建的系统发育树可以得到：①谷精草科独立形成一个植物类群，支持谷精草科独立成为谷精草目；②谷精草科与鸭跖草科聚成一个大的类群，说明两科的亲缘关系较近，并且表现为平行进化；③灯心草科不近缘于谷精草科，与禾本科相比，灯芯草科与莎草科之间存在更近的亲缘关系；④在进化程度上，灯心草科比谷精草科原始；禾本科与谷精草科的亲缘关系最远，并且在这几个科中处于最原始的进化地位；⑤系统树还支持谷精草科内部的系统关系，支持谷精草属在谷精草科中的原始系统位置。

This supported that Stemonaceae should be separated from Liliales and placed in Pandanales. Affinities and speciation of the species in Croomia The two Asian species of Croomia were more closely related to each other than either is to Northern American species.

Croomia的种间关系该属的3个种中，北美的C.pauciflora与两个亚洲种在分子树上已经分歧，根据单倍型和分子树该种与亚洲种的分离时间较早，很可能是从C.japonica的日本居群衍生形成或迁移到北美大陆的。

Any of various Australian evergreen shrubs of the genus Gastrolobium having whorled compound leaves poisonous to livestock and showy yellow to deep reddish-orange flowers followed by two-seeded pods.

产于澳大利亚的几种紫龙骨豆属的常绿灌木之一，具有有毒的轮生复叶，花美丽、黄色至略带微红的橙色，荚果内有两粒种子。

By comparing the results of both counts, one can study the gross frequencies of the dominants as well as fluctuations in the densities of the rarer but more environmentally sensitive species.

将两次的结果会在同一张图上，比较，得到含量变化最显著的种属，即为比例少但环境敏感的species 。

Hyponymy上下义关系------refers to the sense relation between a more general, more inclusive word and a more specific word.

上下义关系实际是指两词意义之间的关系分别表示的是逻辑上的属的概念与种的概念。

Since the day's misery was over and the next day's misery was still far away, they found a temporary ease of mind and body , an escape into a neutral zone belonging neither to that day nor the next day.

今天的苦算吃完了，明天的苦还远得很，这一夜的身心安适是向不属今明两天的中立时间里的躲避。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
