Based on the cloning FeSOD gene of the HZNH, the recombinant prokaryotic expression vector, PQESOa/FeSOD, was constructed and digested with restriction endonuclease BamH I and Pst I to check its construction. The PQE30a/FeSOD was then transformed into E.coli Ml5 and induced with IPTG. The high expression in vitro was obtained and analyzed on SDS-PAGE gel. The*results showed that the target proteins held a 37% portion in whole bacterial proteins and consisted of two parts, the soluble proteins and inclusion bodies. The soluble proteins in the aqueous layer, checked by means of activities of FeSOD enzymes and analyzed by means of activities of isozymogram from PAGE, demonstrated the induced expression proteins had the active nature of FeSOD enzymes.

Methods 12 guinea pigs of 20 months with 3 cm×3 cm hair sheared from their backs were divided into control group and experimental group. Rhodosin and deer serum preparation was besmeared on the skin of guinea pigs in experimental group, and cosmetic matrix was besmeared on the skin of animals in control group for 60 d. The distribution of type Ⅲ collagen was observed with Sirius red staining and HE staining. The fission index of the cells of stratum basale, the thickness proportion of stratum corneum to epidermis, the volume density of the collagen fibers and small blood vessel in dermis, the number of fibroblasts in aging skin were meassured with technique of sterology.

In this thesis, a series of complexes based on aromatic multicarboxylic acids have been successfully synthesized in solutions or under hydrothermal conditions. Their structure and properties are investigated.(1) Eight complex compounds have been synthesized and characterized by X-ray single crystal diffractive technology: The eight complexes are listed as following: [Cu242] complex 1 [Cd22(H2O)4]·4H2O complex 2 [Co(H2btc)(H2O)3] complex 3 [Co2(H2O)2]·H2O complex 4 [Ni22(H2O)4] complex 5 [Cu22(H2O)4] complex 6 [Co(H2biim)2(H2O)2](H2btc) complex 7 [Zn(H2biim)2(H2O)2](H2btc) complex 8 The structure of complex 1 is dinuclear complex resulted from weak interactions（0-D chain）; complex 2 is 1-D chain stucture result from interactions of water molecules; complex 3、4、5、6 are coordination polymers using hydrothermal synthses, where the first kind ligand is H4btc, the second kind ligand is phen and Co2+、Ni2+、Cu2+ as center ions, respectively. While the coordination enviroment of Co2+ is the same in complex 3, the coordination geometries around the Co atoms in complex 4 are obviously different because of the different reaction conditions. In complex 4, the 1-D chains are connected into 2-D layer through carboxy groups of ligand H4btc. The structures of complex 5、6 are 1-D chain stucture result from interactions of carboxy groups in ligand H4btc. Complex 7、8 are homeomorphy compounds. Either of them are linked to the 3-D chains through intermolecular hydrogen bonds. Each H4btc lose two protons and H2btc2- acts as negative electron balance.

SiC polytypes of 6H and 15R and a transition zone between the two were observed under HREM and TEM and discussed from the point view of the crystal structures; the clear evidence of Al〓C〓 nucleated in the SiC particle was provided, indicating the aluminum penetrating the SiC grains is already carbon-saturated and, consequently, Al〓C〓 crystals grow in the particles wherever a temporary local supersaturating is produced; The experimental observation indicated that the types of the interface between SiC and Al are variable and the distribution feature of reaction product, Al〓C〓, were also given in the present work: to be nucleated on SiC, to be aggregated at SiC/Al interface zone or to be aggregated at the crystal boundaries.

通过高分辨透射电镜，本文观察到SiC增强体中6H和15R同质多晶现象及6H-15R SiC转变区，以及另外一种无序的SiC同质多晶，并从其晶体结构的角度解释了6H和15R在晶体内共存的现象。通过高分辨透射电镜，本文给出了Al〓C〓在SiC颗粒内部形核的明证，表明Al〓C〓形核是Al渗透到SiC颗粒内部在C过饱和处在SiC的（0006）面上而形核，而且一种可能的位相关系为A1〓C〓[11〓0]∥SiC[11〓0]。研究结果同时给出了SiC/Al复合材料的界面反应产物A1〓C〓的分布特征：在SiC上形核并生长，聚集于SiC/Al界面去附近，或者聚集于晶界上。

For reconstruction from contours, this dissertation uses Active Contour Model to check the boundary contours. The algorithm can generate single, continuous and close contours quickly. For reconstruction from voxel, this dissertation presents an algorithm to trace the boundary contours from segmented regions based on Active Contour Model. The algorithm can trace the contours of inter and outer connected multi-regions correctly and accurately, and can prevent tracing from jumping out to the neighbor region, also can define the contour precision and contour key points actively as snake is growing up.

对于基于轮廓线的表面重建，利用主动轮廓模型（Active Model，又称Snake Model）来完成断层图象上目标轮廓的提取，可以获得单象素连通的封闭的目标边界轮廓；针对基于体素的表面重建中实施了分割后的体数据，提出了一种基于主动轮廓模型完成二值图象中轮廓跟踪记录的方法，可以对同属于重建目标的内外邻接多区域进行正确和准确的边界轮廓跟踪，使得在跟踪当前轮廓时不会跨越到相邻轮廓，且主动轮廓的精度可以根据参数交互决定，尤其是能够在主动轮廓成长的同时主动定义轮廓关键点。

Please not that a 250 mm wide die opening will produce a film or sheet with less width since you have a "neck in" effect when you pull out the melted resin from the die before it reaches the surface of the chill roll. the width you can achieve depends on the melt strength of the resin as well as the distance between the die lip opening and the chill roll. but in general, about 80% of the die opening width can be achieved.

注意：250毫米宽开口的模头只能获得小于此宽度的薄膜或片材，因为当熔体树脂被从模头拉至冷辊上时会产生&颈缩&效应，最终获得的实际宽度依赖于树脂的熔体强度以及模唇开口同冷辊之间的距离，但总而言之，可获得模头开口宽度80%的产品宽度。
