向量加法

Linear algebra also plays an important part in analysis, notably, in the description of higher order derivatives in vector analysis and the study of tensor products and alternating maps.

这样向量可以用来表示物理量比如比力，可以做加法或和标量做乘法。如此形成了第一个例子：实数向量空间。

In vector algebra, addition are defined to add coordinates entries respectively,and this system of operation is the direct sum Z Z={|a,b are integers} of integers ring Z,the operations are+=,=.

向量代数加法就是这样按照分量加法在运算，再加上按照分量的乘法，这个运算体系就是整数环Z的直和Z Z={|a，b为整数}，其上的运算就是+=，=。

Three-dimensional dynamic finite element methods and theories , improved the Ritz vector method and vibration shapes superposition method are applied to analyze and calculate the dynamic response of drilling string.

本文采用三维动力有限元理论方法和改进的Ritz向量法及振型迭加法对钻柱进行了动力响应分析和计算。

To demonstrate the applicability of the proposed broadband quadrature hybrid, a continuous phase shifter which is based on the vector sum method is tested.

为了证明所提出的正交宽频混合器的可应用性，我们用一个利用向量加法的连续相移器去证明其潜力。

This tests your knowledge of the principles of vector addition and the summation of forces around a point.

这个测试你对向量加法原理及作用于同一点的外力总合的认知。

The operation of finding the sum of two vectors is called vector addition .

求两个向量和的运算，叫做向量的加法。

The algorithm is implemented in different ways, vector addition, through the different forms of execution time is given to prove the efficiency of different algorithms with high and low.

详细说明：该算法用不同的方式实现了向量加法，通过给出不同方式的执行时间证明了不同算法的效率高低不同。

使用MATLAB软件中的基础线性代数、向量和阵列的加法与乘法，以及使用阵列解决多组线性方程式。

Depending on the structural feature of the discernible vector, a plus rule for the discernible vector sets was defined, and a scan vector with concise structure but representing the information table can be obtained through scanning the discernible vector just one time.

根据粗糙集理论知识，定义了一个新概念―差别向量，利用差别向量将信息表转换成差别向量组；根据差别向量的结构特征，定义了差别向量加法法则；运用这个加法法则仅需对差别向量组扫描一次，就可以形成结构简洁却能代表原信息表属性特征的扫描向量。

Addition of angular momentum: Clebsch-Gordan series and coefficients, spin systems, and allotropic forms of hydrogen.

角动量加法：向量耦合（Clebsch-Gordan）级数和系数，自旋系统，和氢的同素异形体。

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。
