The thesis also gives the estimated upper bounds of error decision probability. When the compressor is confined to be a lattice vector quantizer, a explicit mathematic equation for the rate of the performance convergence to the optimum is derived. On the other hand, Distortion Ratio Aproachs to the design of testing system on the basis of vector quantization are put forward, and methods for building the variable length decision tree as well as the fixed length one presented.

在算法方面，提出了失真比矢量量化检验器的设计方法以及可变长和固定码长分类判决树的生成算法；为了解决以矢量量化器为核心的处理系统运算量大，不易实时实现的问题，论文中引入了熵减的概念，在此基础上提出一种快速最近邻搜索编码方法，理论分析及实验结果均证实了这种算法的有效性。

To represent palm-lines, a vector, called line feature vector, is defined by using the magnitude and orientation of the gradient of the points on these lines.

A novel method for image edge detection is presented based on information measurement and Support Vector Machine, which is called ISEDM (Information measure and support vector machine edge detection method).

将信息测度和支持向量机结合在一起，提出了一种新的图像边缘检测方法（information measure and support vector machine edge detection method， ISEDM）。

The picosatellite is characterized by small volume, light weight and low power consumption. Based on these characteristics, a designed micro sun sensor is used to measure the sun vector which is then compared with the sun vector calculated from the orbit propagator. In such a way the picosatellite attitude angle can be obtained.

首先针对皮卫星体积小、重量轻、功耗低的特点，采用设计的微型太阳敏感器测量太阳矢量，与轨道演化计算获得太阳矢量相比，该方法更适合获取皮卫星姿态角度信息。

An extensive technique of tone shading, namely view shading, is introduced in this paper, in which color of an object is interpolated between cool tone and warm tone, based on the angle between surface norm vector and view vector. It is capable of enhancing the silhouette areas.

在分析tone shading类的艺术性绘制技术基础上，本文提出了一种扩展算法，根据物体表面法向量和观察方向的夹角，物体颜色在冷暖色调之间插值，该方法能够突出物体的轮廓区域。

In this paper, we first give an example that the bilateral weighted shift operator in c_0space is hypercyclic operator and first solve the existence problem of hypercyclic operator in c_0or c_0(Z space . And then we investigate the property of weighted shift operator in c_0 space and an important property of the hypercyclic vector of weighted shift operator in c_0 space and c_0 space. At last we give the concept of weak hypercyclic operator and weak hypercyclic vector , and give the equivalence between the weak hypercyclicity and the hypercyclicity in l~1 space.

本文首先给出了c_0空间上的一个双边左加权移位算子是超循环算子的一个例子，首次解决了c_0 或c_0(Z 空间中超循环算子的存在性问题；接下来分别研究了c_0和c_0空间上的加权移位算子的性质以及c_0和c_0空间上的加权移位算子的超循环向量的一个重要性质，最后提出了弱超循环算子和弱超循环向量的概念，并且给出了I~1空间中弱超循环性与超循环性的等价性。
