The characteristic vector of the real symmetric matrix should be found out, which is orthogonalized and normalized to a standard orthogonal base and is used as row vector to construct the transformation matrix P, so the P~(-1)AP can be made into diagonal matrix.

实对称矩阵A经相似变换P-1AP可化为对角矩阵，在x =Py 下，不一定能化A的二次型为标准型；应寻求对称矩阵A的特征向量，将其正交化并单位化作为标准正交基，作为列向量构造变换矩阵P，可使P-1AP=Λ为对角阵，在x =Py 下，要将二次型化为标准型，且二次项系数即为对角阵Λ主对角线上元素。

Divide the whole region D into finite units and corresponding link points may be obtained. Constructing the equation of variation calculation about every element leads to the finite number of equations. Further more, algebra equation group for general synthesis are gained by adding these finite number of equations, that is,{T}={P} where is the coefficient matrix of the equation group, or say the temperature rigidity matrix,{T} is the row vector of unknown temperature and {P} is the row vector of the terms on the right side of the equation.

然后将整体区域D划分成有限个单元并得到相应的有限个节点，从而可以得到关于每个单元的变分计算方程，将这有限个方程相加就得到了总体合成的代数方程组，即{T}={P}，其中为方程组的系数矩阵，也称温度刚度矩阵，{T}为未知温度值的列向量，{P}为等式右端项组成的列向量。

Firstly, the digital watermarking was transformed randomly, and then encrypted by chaos. The encrypted watermarking was transformed to one-dimensional row vector, and the pixel value was sorted. The coefficient of primitive image of stationary wavelet transformation was expanded to one-dimensional row vector, too, and then the sorted watermarking was embedded to the sorted low frequency and turned to two dimensions.

本算法先将数字水印图像进行置乱变换，然后将置乱后的水印图像进行混沌加密，将加密后的水印按行展开成一维行向量，并将像素值从大到小排序，将原始图像平稳小波分解得到的低频系数也按行展开成一维行向量，并按从大到小排序。

However,the performance of SVM with Gauss kernel is influenced greatly by the penalty parameter C and the scale parameter σ.

支持向量机的识别性能对参数的选取是敏感的，惩罚因子C和核函数参数σ对支持向量机性能会产生重要的影响。

The design of vehicle type classification based on Support Vector Machine is collecting characteristic parameters provided to segregator after vehicle image preprocessing and feature extraction,and classifying the type of vehicle by using technique of Support Vector Machine and binary decision tree according to vehicle image from video camera.

基于支持向量机的车型分类的设计思路是通过视频采集获得车辆图像，对车辆图像进行图像预处理和特征提取后，得到分类器所需数据特征，而后采用支持向量机和二元决策树对车型分类。

This software uses Visual Basic programming language which establishes procedures, it made the computer can self-action recognize the network's spanning tree, associated matrix, loop matrix, drag coefficient vector ,and flowrate vector and so on, then solute the problem according to flow calculation simulation model that has been established.

该软件利用可视化的Basic软件编制程序使计算机能够自动识别出用户所输入管网的生成树、关联矩阵、回路矩阵、阻力系数向量、流量向量等，然后根据己建立的数学模型进行求解。

This paper mainly deals with invariant subspaces and cyclic vectors of certain diagonal operators on a separable Hilbert space. In this case, a complete characterization is given.

考虑一般对角算子的不变子空间是非常困难的，本文主要研究Hilbert空间上一类对角算子的不变子空间和循环向量，给出了这类算子不变子空间和循环向量的完整刻画。

A given test cubes with unspecified bits that generated by a sequential automatic test pattern generator.

我们使用ATPG产生的测试向量，此测试向量包含未确定的位元，此位元可以填入0或1。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
