In this thesis, the basic arithmetic of PIV software - cross-correlation arithmetic is introduced in detail, During the data process, through processing the two sequential images by the cross-correlation arithmetic, the vector charts of particles velocity can be obtained, so is the chart of absolute velocity, with velocity decomposed into the radial velocity and axial velocity.

本文对试验所获得的连续图像通过互相关算法，获得颗粒速度矢量图，并将速度分解为径向速度和轴向速度，对每一小区域内的颗粒按速度方向不同进行速度平均，获得颗粒的平均速度分布曲线。

Then considering earth rotation and 6-DOF movement,the expression of absolute velocity and absolute acceleration for vehicle centroid are deduced by using transform of vector derivative.

与陆基固定垂直发射条件不同的是，潜射弹道式飞行器是在运动着的潜艇这样的动基座上进行发射的，为了保持发射时潜艇的可操纵性以及发射后使发射艇尽快离开发射位置，发射艇要有一定的速度。

Part: two It gives the shaping-pulse in the time field to achieve the aim of the quantum control and adopts the Bloch vector to analyses the dynamic process of the absorption, dispersion and reflection index.

这项工作的意义在于通过合适的选择调制场可以达到预期的相干控制目的。

In view of the the difficulty of mixture gas's characteristic absorption spectrum line overlapped, a novel seriatim mixture gas recognition method based on Support Vector Machine two classes classification and recognition model was presented.

针对混合气体种类光谱识别中组分气体特征谱线重叠严重的问题，将支持向量机用于混合气体种类光谱识别中，提出了一种基于支持向量机二值分类识别模型的逐一混合气体种类识别方法。

Vector spaces are a central theme in modern mathematics ; thus, linear algebra is widely used in both abstract algebra and functional analysis .

向量空间的一个中心主题在现代数学，因此，线性代数被广泛使用在抽象代数和功能分析。

Vector is the new high school textbooks and the new one of the important contents, it is rich in physical background, it is the object of study algebra, and geometry is the object of study is set,"the number of Form" in a mathematical concept of an abstract algebra, linear algebra and functional analysis of the basic mathematical model.

向量是高中新教材中新增加的重要内容之一，它有着丰富的物理背景，它既是代数研究的对象，又是几何研究的对象，是集"数、形"于一身的数学概念，是抽象代数、线性代数、泛函分析中的基本数学模型。

In order to construct a normalized cDNA silencing library, a novel procedure was adopted to reduce the abundant copy number and increase the rare copy number. Then the normalized cDNA was put into pTRV vector to construct a cDNA library and this cDNA library was screened with the technology of virus induced gene silencing.

然后把均一化之后mRNA反转录得到cDNA，再与基因沉默载体pTRV重组，最后把构建好的载体通过电转化的方法转入到GV3101农杆菌中，从而建立起破色期番茄果实均一化cDNA沉默文库。

Acceleration of gravity in the accelerometer's output is eliminated by vector synthesis.

消除了在实际应用中不同坐标系下重力加速度对传感器输出信号的影响。

I see it as a vector of acceleration of an industry.

我把它看作是软件业的一种加速器。

Likewise, when the force vector angles the same direction as the COG, we are producing propelling or accelerative forces.

同样，当力的角度和 COG 的方向一致，我们可以产生推进或加速的力。

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。
