A new SVM is presented in this paper to solve the approximately linear separable problem of pattern recognition:First,we transform the two convex hulls which are made up of the approximately separable training set to make them separable;Second,we can figure out a separating hyperplane by halving the nearest points method or maximal margin method;Then,we get the approximately linear SVM by solving the dual problem of maximal margin method.

对模式分类中的近似线性可分问题提出了一种新的近似线性支持向量机：先对近似线性分类中的训练集所形成的两类凸壳进行了相似变形，使变形后的凸壳线性可分，再用平分最近点和最大间隔法求出理想的分划超平面，然后再通过求解最大间隔法的对偶问题得到基于相似压缩的近似线性SVM。

The main content and results are showed as follows:(1)Chitosan was degraded by high pressure homogenization, and its effect increased with molecular weight of original chitosan, pressure and number of cycles, decreased with the concentration of chitosan, while both the concentration of acetic acid or sodium acetate and temperature had a negligible influence. What\'s more, theoretical model was built and the mechanism of homogenizer was discussed.

2采用高压均质-H_2O_2联合降解壳聚糖，其降解效果随H_2O_2溶液浓度的增大而提高，随壳聚糖溶液浓度的增大而降低，随HAc溶液浓度的增大先升高后降低，随均质压力和温度的升高而提高，随循环次数的增加而提高。

In order to develop a safe and effective immunoadjuvant to enhance the immunity and resistance of animals against infection, a novel CpG Oligodeoxynucleotides containing 11 CpG motifs was synthesized and inserted into the VR1012 plasmid, designated as VR1C. Then the recombinant VR1C was entrapped with Chitosan nanoparticles prepared by the method of ionic cross linkage, and employed to inject muscularly 3-weeks old Kunming mice; the blank VR1012 packed with CNP and saline were used to inoculate mice as the control groups. 28 days after inoculation, all mice were orally fed with 0.4ml 2x108CFU/ per mouse virulent hemorrhagic enteritis E. coli to challenge the resistance against infection.

For the accuracy and complexity of different complexity analysis method are different, firstly, the ultimate strength of pressure hull is mathematically analyzed and calculated by ANSYS, and then the empirical formulation is modified according to the modified factors, which are gotten by the accurate model of ANSYS. So that the calculation accuracy will be improved and the calculation time will be reduced after the analysis model of pressure hull structure is integrated.

不同分析方法的准确度和复杂度不同，本文采用ANSYS这种高精度分析方法对于载人球壳的极限强度进行计算，并根据所得到的计算结果来对采用经验公式方法得到的结果进行修正，使得多学科设计优化模型中集成修正后的载人球壳结构分析模型以提高计算结果的精确度和降低运算时间。

METHODS: Chitosan scaffolds were prepared by 6% chitosan based hydrolgels produced from acetic acid and chitosan. Schwan cell of neonatal rat sciatic nerves was cultured using enzymatic digestion adherent method.
