Moreover, the inner cone has the characteristic of Lewis basis with high electron density because of the lone-pair electrons of oxygen atoms stretching towards it and can form inclusive compounds with varied compounds. The special structure of CD is very important to separate and analyze enantiomers, which has become the most important mainbody of super-molecular chemistry and greatly improved the developments of bioscience and pharmaceutical chemistry.

环上具有多羟基，具有亲水性。O原子的孤对电子朝向内腔，使内腔具有高的电子密度，具有Lewis碱的特征，能和多种化合物形成包合物，这种结构因素在手性识别上起作用，目前它已经发展成为超分子化学最重要的主体，对促进生命科学和药物科学的发展具有重大意义。

This study showed that population genetic diversity was much lower than other Gymnosperm and there was no distinct genetic differentiation among individuals in this population. In order to protect or preserve its genetic resource,it is suggested that the most individuals in the population should be selected as we can.

研究结果表明：AFLP方法是一种十分有效的检测种群遗传多样性的分子标记，既具有可靠性又有方便高效性；元宝山冷杉种群的遗传多样性水平很低，种群内各个个体间的相似性系数很大，遗传关系很近，无明显的遗传分化，这说明该种群的适应能力差、进化潜力有限，濒危程度很高；若要保护或保存这个物种的遗传资源，建议应该选择种群内尽可能多的个体进行保护。

The 28S rDNA molecular phylogenetic trees showed: 1 entoprocts and phylactolaemate ectoprocts constituted a sister group, strenghthening the opinion that entoprocts should be reunited into phylum Bryozoa; 2 the cheilostome gymnolaemates was obviously non-monophyletic; 3 bryozoans itself was polyphyletic beyond any doubt, its main lineages were scattered in different positions of the lophotrochozoan trees; 4 to our great interests, the phylogenetic position of cheilostomes was between the diploblastic and the triploblastic, indicating they may play an important role during the evolution route from the diplobastic to the triploblastic animals.

28S rDNA分子系统树显示，内肛动物和被唇类外肛动物聚在一起并互为姐妹群，支持将内肛动物重新归入苔藓动物门的结论；唇口目裸唇类外肛动物绝非单系发生；苔藓动物本身也不是单系发生的，其主要类群分别位于触手冠担轮动物系统树的不同位置，特别是，唇口目苔藓动物的系统地位介于二胚层动物和其它三胚层动物之间，可能是二胚层动物向三胚层动物演化过程中的一个关键类群。

Our three groups in SCBB will conduct one project in this grant (three projects in this grant total), which is "Screen mutants interfering the development or regeneration of endodermal organs and study their functional mechanisms". In this project, stem cell and zebrafish will be used as models to elucidate the mechanisms of the development of endodermal organs.

我院的三个课题组负责此项目的课题三《正向遗传突变筛选具有内胚层器官发育或再生缺陷的突变体及致变基因的功能机制研究》，将采用干细胞和斑马鱼模型，研究内胚层器官的机制，特别是分子调节网络的整体性和时空性，为防治肝脏和胰腺的重大疾病提供坚实的理论基础。

Interestingly, AQP4 distribution in glial cells and ependymal cells showed certain directivity, but the former was mainly in the membrane side contacting with capillary endothelial cells and the latter mostly in the basolateral membrane of ependymal cells.

AQP4在正常兔脊髓内具有广泛的表达，其表达的解剖定位提示AQP4在脊髓内主要参与水分子的转运及平衡调节、电解质代谢，并受局部调节以适应特殊的功能需求。

Based on our intensive studies on the lactonization of oligo/polysialic acids, we proposed for the first time that the lactone-ring formation of oligo/polysialic acids has three stages. We also provided a novel model to explain the conformational changes of oligo/polysialic acids caused by the repulsing forces among the carboxyl groups of sialic acid residues. Our results should provide novel approaches for further investigation of the structural-functional relationships of oligo/polysialic acids.

在对多/寡聚唾液酸内酯化过程进行深入研究的基础上，于国际上率先提出多/寡聚唾液酸内酯的形成具有三个阶段的观点，并首创性地提出了羧基排斥所致多/寡聚唾液酸分子空间构象改变的模型，为深入研究多/寡聚唾液酸结构与功能的关系提供了新生长点。

At the same time served determination of Miridae phylogeny on molecular level. 10.The phylogenetic relationship between subfamilies constructed based on analysis of the Cyt b 432bp sequences is basically same as that based on EST traits.

从分子水平支持Schuh 1976年提出的盲蝽科内亚科的系统发育关系中这5个亚科相互间的系统发育关系，并确定了合垫盲蝽亚科Orthotylinae在这个关系中的地位，为盲蝽科内系统发育关系的确定提供了重要的依据。

The lipid peroxidation of S. maxima cultured in the presence of 4 to 100mg Se/L analysed showed that the contents of free radicals by EPR and malondialdehyde increased, of which the latter was the products of lipid peroxidation. These resulted in the decrease of the contents of liposoluble matter and percentage of polyunsaturated fatty acids, and the increase of percentage of saturated fatty acids. Using dimethyl sulfoxide , which was oxidized by OH·to form the stable and nonradical compound, methane sulfinic acid , as a molecular probe, we found that the contents of MSA from S. maxima growing in the presence of selenium were higher than those without selenium added, i. e. selenium in vivo was able to scavenge OH. in this alga.

对4～100mg Se/L范围内培养的S.maxima进行脂质过氧化的分析结果表明，加硒条件下藻细胞EPR自由基的含量与脂质过氧化产物的含量增加，造成细胞脂溶性物质含量和不饱和脂肪酸百分含量下降，以及饱和脂肪酸的百分含量相对上升；使用DMSO作分子探针，用它与OH·的反应产物MSA来表示藻细胞OH·含量，发现加硒条件下藻细胞MSA含量低于未加硒的，即硒在藻细胞内具有清除OH·作用。

In temperature range from 25 to 200 ℃, The heat conductivity along the grain of wood is approximately 2.4 or 3 times of that cross the grain. And this result is relative to composing orientation of the molecules interlink inside the cellular wall of wood.

在25～200℃内，热流平行于纹理方向的木材导热系数要大于其垂直于纹理方向的导热系数，前者是后者的2.4～3倍：这种差异与细胞壁内分子链结构的构成方向有关。

Vacuum impregnation method was developed, in which the molecular sieve SBA-15 with a pore size of 36 ran was selected according to the size of the hydrated form of POM.

与此相比，利用较小孔径的分子筛SBA一巧(7 。7nln)作为载体，采用同样方法组装时，由于孔径的限制，POM水合作用的影响，POM在孔道内以单分子的形式存在，难以在孔道内形成纳米晶体。
