It was indicated by UV-Vis spectra characterization that the precursor always contains the tetrahedral Ti species and the octahedral Ti species regardless of the Ti content. Calcination of the precursor resulted in a partial condensation of the octahedral Ti species to form the anatase phase.

UV-Vis 光谱表明，Ti-MWW 合成原粉中含有四面体的钛和八面体的钛，而八面体的钛属于一种骨架外钛，未经酸处理而煅烧会使部分八面体钛缩合形成锐钛矿，而经过酸处理和煅烧后的分子筛则几乎不含有锐钛矿。

Segments of Adh gene in azuki bean (variety KS 5), covering an interval between partial intron 3 and intron 9, were amplified and sequenced with two pairs of primers. The result has proven the viability of using conserved sequences in a completely sequenced gene of one species to clone same gene in another species. In the comparison between Adh genes of azuki bean and pea, high sequence similarity (about 80%) in exon and long length difference (up to 116 bp) in intron were found. Besides, the edge regions of Adh introns with GT/AG counterparts and more conserved sequences than central regions was observed in both species.

利用两组引子对完成红豆(高雄5号)Adh基因之部分解序，其范围包括部分intron 3至intron 9之间的区域，也印证利用基因之已知保守序列可选殖另一物种之相同基因，红豆与豌豆之Adh基因序列比对结果显示两者之exon均较intron有较高之GC百分比(分别为41.0 ~ 48.7%及23.3 ~ 35.2%)，且两者在exon区域之DNA序列相似程度约80 %，而在intron区域中则有明显的序列差异存在(长度差异最高可达116 bp)，但是intron外侧序列均具有GT/AG组成且相对较中央序列具有保守性。

The results showed that Mephitinae was divided from Mustelidae firstly,and then the remain were divided into two branches.Martes species and Wolverine were contained in one branch which was formed a sister group with Eurasian badger of Melinae;Lutrinae species and Polecat of Mustelidae formed a sister group,and Marbled polecat was sister to the clade of Lutrinae species and Polecat.They formed another branch.Eurasian badger has the closest relationship with the Sable of Martes,and Lutrinae has the closest relationship with Mustelidae.

以狼为外类群，应用邻接法构建鼬科线粒体控制区全序列的系统进化树，结果表明：臭鼬亚科最先从鼬科中分化出来，随后剩余类群分为两大支系，即貂属种类与貂熊聚为一支，并与獾亚科的狗獾形成姐妹群；另一支为水獭亚科的物种与鼬属的林鼬形成姐妹群，再与虎鼬聚在一起，狗獾与貂属的紫貂亲缘关系最近，水獭亚科与鼬属亲缘关系最近。

About 40 species: predominately in temperate regions, some species in subtropical regions; 17 species (11 endemic) in China.

大约40种：主要在温带地区，一些种类在亚热带地区；中国有17种(11特有种)。

Rhus typhina is a defoliated shrub or little arbor species of Anacardiaceae. This species possessed developed root system and strong sprout ability and was considered as one of the promising tree species of restoration and costruction of vegetation, prettification of environment and construction of scenic garden.

火炬树为漆树科盐肤木属落叶灌木或小乔木；其水平根系发达，根蘖力强，是植被恢复与构建、环境美化和风景林营建的优良树种之一。

Up to now,30 species of virus,100- plus species of bacteria and30 species of protozoon have been discovered.

蝇类传播的微生物很多，已证实病毒约30种，细菌100多种，原虫30多种并可携带多种蠕虫卵等。

This paper discusses the cultural environment of historic city from the ecological point of view,establishing the concepts of cultural gene,cultural species,and cultural ecology,confirming the valuable cultural species which should be paid attention to,especially the rareness and the declining species.

提要 本文从生态学角度研究历史文化名城的文化环境。建立了城市文化生态系统的文化基因、文化物种、文化生态学的概念，确定了历史文化名城中有价值的文化物种，分析了物种在系统中的数量和变化状况。

So, the species may survive in metapopulation form with the equilibrium of extinction and recolonization. We are interested in the effect of habitat fragmentation on the species, and the adaptation of species to habitat fragmentation, which would be useful for conservation strategy and design of natural conserved region.

栖息地片段化将给生活于其中的物种带来怎样的影响，同时物种又是如何适应栖息地片段化并得以续存，这是我们现在所关注的主要问题，这对探讨物种的保护策略及保护区设计原则具有重要意义。

But the species diversity has no significant correlation with the minimum distance to source area. This suggests that immigration and recolonization for Raniformes species have hardly occurred on Zhoushan archipelago after the islands were formed, and the species number on the islands is under the "non equilibrium" status.

但物种多样性与离物种源的最小距离没有显著相关性，这说明岛屿形成后蛙类在岛屿间很少发生迁移和再定居，物种数处于"非平衡"状态。

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。
