查询词典 vector product

Abortus, amplify BP26 gene by PCR and clone to pMD18-T simple vector. Identify the constructed recombinant plasmid pMDBP26 by sequencing, then subclone to vector pET-28a. Transform the constructed recombinant plasmid pETBP26 to E. coli BL21(DE3) for expression under induction of IPTG. Purify the expressed product by histidine-binding resin column chromatography and identify by Western blot.

提取布鲁氏菌基因组DNA，用PCR扩增出BP26基因，并克隆到pMD18-T载体上，测序正确后，再亚克隆至pET-28a载体上，转化到大肠杆菌BL21(DE3)中，用IPTG诱导表达，经组氨酸结合树脂柱纯化，并对纯化后的表达产物进行Western blot鉴定。

Under the condition of quantifiable product characteristics, the model of product configuration based on product characteristic vector is constructed, and the basic theory and process of knowledge expressions are given.

在产品特征可量化的条件下，建立基于产品特征向量的产品配置模型，给出知识表达的理论基础和实现步骤。

Aiming at the situation that product configuration can not adapt to different products and knowledge expression is complicated, product configuration based on product characteristic vector is presented.

针对产品配置对不同产品的适应能力差、配置知识表达复杂的现状，提出基于产品特征向量的知识表达方法。

The cross product of the vector operator with the vector w .

向量算符与向量 w 的外积。

Data sample pretreatment of decision tree and Support Vector Machine method is conducted by the documents of product design knowledge segmentation processing, feature extraction, feature merger and expression vector.

通过对产品设计知识文档的分词处理、特征抽取、特征合并及向量表达，为决策支持向量机方法提(来源：d6f5A6fBC论文网www.abclunwen.com)供样本数据预处理。

The dot product of the ▽operator with a vector defines the divergence of that vector .

算子▽与一个矢量的点积定义为这个矢量的散度。

By the procedure, we first use the cosine values of the angle between view vector and normal vector on each vertex as the texture coordinates, through calculation of the dot product of the two vectors. The derivative of radial curvature on the model surface is used as the second pass texture mapping coordinates, by a calculation using Euler formula.

该方法首先通过模型顶点的视线向量和法线向量的点乘积计算其夹角的余弦值，作为第一步的纹理坐标进行映射；再通过欧拉公式计算径向曲率及其方向导数值，作为第二步映射的纹理坐标。

In every case, then the vector force equals the product of the mass and vector acceleration.

因此在所有情况下，力矢量等于质量和加速度矢量的乘积。

In order to give the geometric meaning of Inner product of two vector,the textbook printed by People's Education Press use the concepts of "projection" and "image" of vector.

为了给出两个向量的"数量积"的几何意义，现行人教版教材引入了向量的投影和射影的概念。

In order to give the geometric meaning of Inner product of two vector,the textbook printed by People s Education Press use the concepts of "projection" and "image" of vector .

二者字面意思基本一样，但"投影"是一个实数，"射影"是一个向量，二者不是同一类事物，而且对向量的射影的表述有不当之处。

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。
