向量

In the presence of impulsive noise,the two received signals are combinated,so the estimated impulse response of the channel is the eigenvector of its covariation matrix corresponding to the smallest eigenvalue,which can be realized adaptively using generalization o.

该算法在脉冲噪声环境下，组合两个接收信号，使其共变矩阵最小特征值对应的特征向量为信道的估计，并基于广义归一化最小平均p范数方法自适应得到该特征向量，从而获得时延估计。

This means that the cross product is zero, and therefore that the vectors are at right angles.

还这意味着叉乘为0，因此两向量（译注：矩阵中的行列代表的向量）相互垂直。

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

向量算符与向量 w 的外积。

From linear algebra a normal vector of a plane can be obtained by proceeding a cross product between two vectors of this plane.

从线性代数一个可进行一两个向量的这架飞机获得的产品平面交叉法向量。

With the two vectors, v1 and v2, it is now possible to compute the cross product between them to find a perpendicular vector to the face.

有了两个向量v1和v2，现在我们就可以计算叉乘，来找到正交于面的一个向量。

The vector product or cross product of two vectors, v and w

向量 v 和向量 w 的内积或叉积。

The curvature of a curve; the magnitude of the derivative of its unit tangent vector with respect to distance on the curve:.

曲线的曲率；为单位切向量对距离取导数所得向量的大小

DT/ds| The curvature of a curve; the magnitude of the derivative of its unit tangent vector with respect to distance on the curve:|dT/ds

曲线的曲率；为单位切向量对距离取导数所得向量的大小

Curvature vector must be orthogonal to the slope vector.

曲率的向量必须和斜率向量垂直 4。

The complete pseudo-umbilical submanifolds with parallel mean curvature vector in constant curvature space;2. In this paper,the pseudo-umbilical submanifolds with parallel mean curvature vector in pseudo-Riemannian manifold is discussed.

研究了伪黎曼流形中具有平行平均曲率向量的伪脐子流形，Npn+p为n+p维完备连通伪黎曼流形，它的截面曲率KN满足a≤KN≤b，Mn为Npn+p中紧致的具有平行平均曲率向量的伪脐子流形。

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。
