向量

If two vectors are associated with each other as a dot product, the result is a scalar.

如果两个向量以标量积结合，其结果为一标量。

Dot Returns dot product of two vectors.

返回两个向量的点积

Based on the oil-water flow rate and density obtained with a double-U Coriolis flow meter, and by the help of Support Vector Machine, a direct prediction method of the oil-water respective mass flow rate was developed to avoid the need of study on the complex relation between the slip velocity, water hold up and water fraction.

以双U型Coriolis流量计得到的油水混合物的质量流量和密度为基础，提出了基于支持向量机油水分相质量流量的直接预测方法，避开了直接对滑脱速度、持水率与含水率等之间复杂关系的研究。

Is not the best way of doubling the values in the vector, I've done it this

是不是增加一倍，向量的值最好的方法，我已经做到了这

The contourlet transform used in the system was constructed by dual tree complex wavelet transform followed by critically subsampled directional filter banks, sub-bands energy and standard deviations were cascaded to form feature vectors, and the similarity metric was Canberra distance. The performance of retrieval system was compared including original contourlet transform, non-subsampled contourlet transform, semi-subsampled contourlet transform and CCT under the same system structure.

该系统采用的复数轮廓波变换由双树复小波变换级联临界下采样方向滤波器构成，特征向量采用子带系数的能量和标准偏差连接而成，以Canberra距离为相似度度量标准；比较了基于同样架构的基本轮廓波变换、无下采样轮廓波变换、半下采样轮廓波变换和CCT纹理检索系统的性能。

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。
