We start by introducing some foundations of vector calculus to see how vectors apply on the field of Physics.

本课程从第一章的基础概念开始，先让同学认识向量的基本运算，并且以向量学在物理学上的简单应用，来吸引数学系的同学对於向量学领域的兴趣。

Firstly,a fuzzy Kohonen clustering network is trained with some feature vector consist of the three component vectors,and then the edge points in a new image are directly extracted by using the trained FKCN.

1引言边缘检测是一种重要的图像预处理技术，一直受到研究者的重视。其中，经典的边缘检测方法中最具代表性的有Marr-Hildreth边缘检测理论[1]、Canny最优算子[2]。

Objective To learn the influence of the earthquake in Wenchuan on vectors and vector borne disease, grasp timely the vector species and its density dynamics, and provide a reliable basis for the risk assessment of vector borne disease.

A coding scheme is proposed to eliminate the redundancy of output vectors in pyramidal lattice vector quantization .

并证明了，存在唯一的滤波长度为5的对称双正交小波，不存在滤波长度为5的反对称双正交小波。

The Vector Product node computes the Dot Product of two vectors.

矢量积节点计算两个向量的数量积。

The Karhunen-Loeve transform is used for feature reduction of the feature vectors and creating the subspaces. Then the distance between unknown-classification feature vector and each subspace is calculated to determine the class to which the vector belongs.

A vector that is the sum of two or more other vectors .

两个或两个以上向量相加得到的向量。

28 If you tell me what the Electric field at this point is, which is vectorial sum of the individual vectors. Then I can always tell you what the force will be, if I bring a charge at that location.

电场是向量的加总，如果你告诉我这点的电场是多少，我一定可以告诉你一个被带到这里来的电荷所受的电力是多少。

If the two vectors are the same length, it is easy.

如果两个向量的长度是相同的，它很容易。

An example of what you can do with vectors.

是你可以用向量的例子。"/页"

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。
