The author explicates some developing aspects in the field of IC industry as suggested areas of future work. The original points of this dissertation are as following: 1. In this dissertation, we got the quality learning curve of China's IC manufacturers by regression. On the base of questionnaire, we later explained the reason of the reverse S type quality learning curve and the tendency of change in quality learning curve. 2. The evolution of technical unit of China's IC industry is calculated in this dissertation. We also explained the reason of technical unit splitting in the way of economic and technology. 3. In this dissertation, we described the environment difference in capital, technology transfer, human resource and market in USA, Japan, Korea, Taiwan and China, and gave some suggestions on the government's role in the development of China's IC industry.. 4. In this dissertation, we established an SD model of China's IC industry, and by using this model, we got some suggestions for future development in China's IC industry.

本文的主要创新之处在于：（1）用回归分析方法实证研究了我国集成电路企业的质量学习曲线，并在调查分析的基础上，对反S型质量学习曲线的历史成因和未来走势进行了研究；（2）对世界及我国集成电路产业技术单元的变化趋势进行了定量研究，从经济和技术角度解释了当前集成电路产业技术单元细化的原因；（3）从资金、技术、人才、市场角度系统总结研究了发达国家在集成电路产业发展环境建设中的成功经验，并结合我国集成电路产业发展的实际情况，对我国集成电路产业发展的政府行为提出了一些建议；（4）建立了狭义集成电路产业、材料业、设备业发展的系统动态模型，并利用该模型对不同投资结构下我国集成电路产业系统未来的演变进行了模拟研究，这一研究结果可以为我国集成电路产业今后发展提供一定的决策依据。

Algebraic curve is commonly used in CAGD. Traditional curve interpolation is in various forms of spline fuction. Although better result can be obtained by spline curve, the former two of elliptic, hyperbolic and parabolic shapes can not be represented by spline curve. An exploring research in this aspect is made in this thesis.

代数曲线是CAGD中经常用到的曲线，以往的曲线插值基本上是采用样条函数的形式，采用这种形式虽然能够获得很好的效果，但样条函数所能表达的形状都是抛物线型，对椭圆型与双曲线型曲线的表示是无能为力的。

比如参数曲面与平面的交线就是一条平面代数曲线；平面参数曲线的等距曲线也是一条代数曲线。

In the term of unloading and opposite side loading, let the stress-strain curve have the same form of skeleton curve, the curve uses the last unloading point as its starting point, and uses soil's ultimate stress level as its asymptote. Then the hysteretic curve is constructed.

在卸载和反向加载时，采用与骨架曲线相同的函数形式，并以前一次卸载开始点作为起点，以土体的极限应力水平作为渐近线，构造出土体动力本构模型的滞回曲线。

A novel design scheme for digital optical switch with high extinction ratio by employing S curve waveguide at the end of the Y branch ii proposed. Higher extinction ratio then that of the device without S curve waveguide is obtained by applying certain synchronous voltage to tie Y branch and the curve electrode of tie S curve waveguide.

文章提出一种关于非对称电极低串扰数字光开关的新型设计方案，在Y分叉后端引入S弯曲波导，通过在Y分叉处的非对称电极和弯曲波导的弯曲电极处施加一定的同步电压，实现了比没有S弯曲的开关更低的串扰。

Curve C at the spot P(x0, y0) curvature is the maximal circle of the curve C tangency at the spot P(x0, y0). Contrail curve G of the center D of curvature circle entitles evolute of curve C.

曲线C在点Px0，y0）曲率圆是与该曲线C相切于点P(x0，y0的最大圆，曲率圆的圆心D的轨迹曲线G称为曲线C的渐屈线。

Carried out generalized Mises yield criterion , yield curve on the n flat face was circle curve, and different elected parameters correspond to external angular point circumcircle、 internal angular point circumcircle and incircle of Mohr-Coulomb unequiangular hexagon. According to unequiangular hexagon, circle yield curve which had the same area as hexagon can be found, and corresponding yield criterionwas equilateral circle yield curve.

3广义米赛斯准则在π平面上的屈服曲线为圆曲线，选择的参数不同对应有莫尔—库仑不等角六边形的外角点外接圆，内角点外接圆和内切圆，对于不等角六边形，还可以找到一个面积和六边形相等的圆屈服曲线，对应的屈服准则为等面圆屈服曲线。

First, the relative curvature of a certain curve at its first end and the directional angle of the first port tangent vector of that curve as well as the weight factor of the interpolation curve are given, then all the other control vertexes can be gotten by using the conditions of G continuity, and a method to construct transitional curves is also introduced so that we can get the closed interpolation curve which achieves G continuity globally.

首先给定某段曲线的首端相对曲率和该段曲线的首端切矢量的方向角以及插值曲线的权因子，然后利用G2连续条件求出其余控制顶点，并给出了构造过渡曲线的方法，得到了G2连续的闭插值曲线。

The properties of the new method are that (1) the equations that the quartic Bézier curve has to satisfy for being C 2 continuous are strictly row diagonally dominant;(2) the discontinuous points of the curve are at the given data points;(3) the curve is locally adjustable;(4) if the given data points are convex, the constructed quartic Bézier curve is convex.

用样条函数方法构造插值样条曲线曲面，曲线曲面的精度和形状是由给定的数据点和端点条件唯一确定的。在有些情况下，例如，对文献 [7～ 9]中的数据点集，由样条函数方法构造的C2 插值曲线是不可接受的，但由于没有额外自由度，无法调整曲线的形状。
