Scanning electron microscopy,transmission electron microscopy,circular dichroism and small-angle X-ray diffraction were used to analyze the aggregation mode of CSG in the organogel phase.A hierarchical self-assembly model was proposed to explain the transition from molecular to primary and secondary structure.It is shown from our results that CSG can aggregate into a micellar fibril nanostructure with high length-to-width ratio which is bundled and entangled to form a three-dimensional(3D) network that immobilize the fluid component probably by surface tension.Moreover,sol-gel polymerization of tetraethoxysilane was carried out using CSG in the gel phase.

通过扫描电镜(ScanningElectron Microscopy，SEM)、透射电镜(Transmission Electron Microscopy，TEM)、圆二色谱(Circular Dichroism，CD)和小角X—射线衍射仪(Small-angle X-rayDiffraction，SAXRD)考察CSG分子自组装行为结果表明，CSG形成的聚集体具有多级结构：首先CSG通过手性堆叠自组装形成直径在9—10nm的细纳米纤维，这些细的纳米纤维再以不规则的六方堆积的方式进行排列，构成直径在40—100nm的粗纳米纤维(即细纳米纤维的&捆束&)，最后粗纳米纤维互相粘连形成三维网络状结构，使有机溶剂&固定&，从而形成凝胶；以CSG有机凝胶为模板，四乙氧基硅烷为前体，通过溶胶—凝胶聚合的方法制备了直径大约为100nm的二氧化硅纳米管。3。

This study provided some new evidences for the phylogenetic relationships of Rhopalocera butterflies and its subgroup Papilioninae through the primary and secondary structure analyses of 16S rRNA gene sequence, aiming at setting up a more scientific and reasonable systematics category for the butterflies, especially for those distributed in our country.

本研究通过对凤蝶亚科以及蝶类各主要类群的16S rRNA基因序列的一级和二级结构的系统学分析，旨在为蝶类的系统分类和系统演化研究提供一些分子佐证，为进一步建立一个更为科学的自然分类系统提供部分相关基础资料。

Because traditional "1-9 scale" method is unable to reflect the real thought accurately, which leads to incorrect judgments, an improved scale method based on trigonometrical fuzzy numbers was used in the present assessment system, and the relative weights of both primary and secondary indexes were designed. Thus the assessing results reflect the real thought more accurately.

由于传统层次分析法的&1～9标度&方法不能精确地反映人的实际思维，从而影响最终的判定结果，本评估体系借鉴了三角模糊数表示的改进方法来计算权重值，并对一级指标和二级指标的相对权重均进行了权重设计，得出的结果更加精确地反映了人的实际思维。

A mathematical model of the direct chill casting process for superlight Mg-Li alloy (LA141) slab has been developed using the finite differential method. Thermal boundary conditions including primary and secondary cooling conditions, have been selected based on knowledges of the physical process and the literatures. The variations of heat transfer coefficient between slab and dummy block interface resulting from the deformation of the slab have been considered.
