向量

The current signals were gathered in the tests, and processed by wavelet package transform. A characteristic vector was constructed by the energy of different frequency segment, which was calculated by using the coefficient of wavelet package transform of the current signals. The vector shows that the energy of low frequency segment is of the majority of the total energy, and becomes larger as the interelectrode gap decreasing.

在线采集真实电解加工过程中的电流信号，用对实测信号进行小波包分解和重构后的小波系数计算各频段的能量，构造一个由不同频段能量组成的特征向量，发现特征向量的低频分量占总能量的大部分，随着平衡间隙的减小，低频分量能量增大。

A vector named as relation vector to describe relations existing between intervals presented is used by Allen in his Interval algebra theory.

Then with the use of general inverse and matrix projection theorem,a new parameter with good identification effect is deduced,which is called projection modulus of residual vector ,and with which the damaged element is easily identi.

为了找到一个对小损伤较敏感的参数，在结构自由振动微分方程基础上，结合损伤结构的测试数据(用有限元模型的计算结果来模拟)，得到残余向量，利用广义逆和矩阵投影定理，导出了一个具有很好识别效果的参数：残余向量投影范数。

However, in regression model if there are features that are not completely relative or even completely irrelative to the problem, the difference of features' correlative degree to the problem becomes large and it may affect the performance of support vector regression machine.

基于统计学习理论的支持向量回归机有比较好的泛化能力，然而当样本含有与该问题不完全相关甚至完全无关的特征时，会使得各个特征对问题的相关程度差异很大，从而使得支持向量回归机的效果受到影响。

A matrix which has a set of complete eigenvector system can be similar orthogonally to a diagonal one through reduce it to Jordan's normal form, and based on this property,the reducing matrix was taken as the transformation one. Thus all eigenvalues and eigenvectors of the system can be obtained.

利用具有完全特征向量系的矩阵在约化若当标准型过程中可正交相似对角矩阵的特性，将变换矩阵取为约化若当标准型过程中的分解矩阵，从而求出所求系统的特征问题的全部特征值和相应的特征向量。

For this purpose it employed a technique based on fractal dimension,multi-fractal and lacunarity concepts,and constructed feature vectors based on the concepts combined with intensity.

引入了分形、多重分形和空隙等概念，建立了其特征向量，结合灰度特征进行了图像分割实验，通过对提取出来的特征向量进行平滑滤波处理，采用 K 均值分类算法有效地保证了分割效果。

"Transform",The Laplace transform can be used to solve the state equations for the state and output vectors.

"，"拉普拉氏转换可以用来解状态方程的状态向量和输出向量。

The improved algorithm shortens the length of bit vector and reduces storage space.

该算法的元组分割缩短了位向量的长度，减少了位向量的存储空间和读取次数。

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。
