This paper put forward the optimized methods include reconstructing the characteristic curve by reasonable use of the adjust tools and analyse tools of the modeling software , admeasuring the automotive model surface correctly , simulating the breaking surface and creating the surface in the right turns which is good for modeling a smooth and exactitude surface . at last , after the correct analysis of the factors which are effect to the surface construction , a smooth and exactitude surface of the similar diamond concept car has been constructed by using the right optimize method 本文通过合理利用反求软件中的造型工具和分析工具，正确划分反求模型的造型区域，使用正确的曲面造型方法，对反求曲面的特征网格线进行二次优化，并对突变曲面进行拟合再生成处理及建立合理的曲面生成顺序等方法，最终获得了仿型度和光顺度都很高的反求曲面。
Four details countenneasures were suggested , which would be benefit to improve die situation of current venture capital industrial . at the end of paper , die diesis designed three policies for government : a ) change die functions and die way of government behavior in development of venture capital industrial 第三，风险投资中政府行为次优化是公共选择结果的一种反映，政府在风险投资发展中所表现出的行为是各个利益主体之间冲突和均衡的产物，而且政府行为也是有限理性人，也导致了政府行为缺陷。
According to the optimization of wagon flow organizing , the author regards xiang - shi line and interrelated technical station as a logistic system , and proofs the optimal layout of this line , at the same time , applies the method cost , the avoiding vice optimizing , the means of comparison and analysis etc . combing area of xiang - shi line , the author analyses the present situation and main problem 本文从车流组织优化入手，把襄石线及相关的技术站视为一个物流系统，从系统优化的角度论证襄石线最优的区段站设置方案，运用了系统管理观念，包括总成本法、避免次优化、得失比较分析法等。
Basing on the statistical inaming t ' heory ( slt ) , the thesis discusses the svm problems in linearly separable case , lineariy non - separable case and non - linear separable case , and induces a convex quadratic programming ( qp ) problem with an equation constrain and non - equation constrains . then one program on solving the op problem is proposed 概述了统计学习理论的主要内容，推导了支持向量机方法在文本线性可分、线性不可分和非线性可分情况下实现分类的数学公式，将学习问题转化为一个在等式约束和不等式约束下的凸二次优化问题，总结了求解的过程。
Abstract : it provides a kind of new nonlinear integrator and its mathematical model . its frequency responses is disscussed by the harmonics linearization method . its phase lag is found to be only 27 . 6 , all high order harmonics are very small , and it is very resistant to disturbances . by using it , an two - objective optimum control system is designed . it has very good control performances and will have good prospects in application 文摘:提出一种新型的非线性积分器，给出它的数学模型，并用谐波线性化原理讨论它的频率特性，其幅频特性起积分作用，而相位滞后仅27 . 6 ，高次谐波分量小，抗干扰能力强.应用这种积分器设计了一个双目标优化的二次优化系统.仿真结果表明，系统的控制性能好，具有广泛的应用前景
