向量

This thesis has mainly contributed two results in theory: one is that the covariance matrix is not positive definitive if the number of sampling is least than the number of variables, the other is that the covariance matrix of discrete sample is positive definitive if and only if the sum of every random column vector of data matrix is non I-linear combination.

本论文在理论上，主要得出两个新的结果：ⅰ抽样调查中，若样本的个数少于变量的个数则样本协方差矩阵恒为非正定；ⅱ离散型样本协方差矩阵正定的充要条件是样本资料阵的各随机列向量是非I-线性组合。

Methods Firstly, 2-D matrix X with each ECG-cycle as a column vector was constructed. Secondly, the principal components of X based on Karhunen-Loeve Transform were gotten to reconstruct X from the first eigenvector of XXT.

首先以逐拍心电波形为列矢量构造二维矩阵X，再通过KL变换得到X的主分量，然后由X的最大特征向量重构X。

We would like to know the number of rows and number of columns.

我们想要知道向量的行数和列数。

It's a linear combination of the columns.

这是列向量的线性组合。

This method can be used to reduce power dissipation of combinational logic.

本文通过上述问题的研究，在设计流程的不同阶段解决自测试设计的测试功耗问题：在高层综合阶段，引入功耗约束和模块随机响应模型，自动生成低测试功耗、低面积开销的RTL电路结构；在逻辑综合阶段，针对测试功耗分别优化了电路结构和测试向量生成电路，以微小的故障覆盖率和面积开销为代价，最大程度降低测试功耗。

At first, a model for selecting optimal parameter v in v-SVM is presented in this paper, which bases on mathematical programming with equilibrium constraints. The model is a nonlinear problem which has smoothed objective function and with complementary constrains.

首先本文给出了一种基于平衡约束规划的v-支持向量机中参数选取模型，该模型是一个具有光滑目标函数的且带有互补约束的非线性规划问题，通过求解该问题得到v-SVM中泛化性能较好的参数v，并进行了数值实验，证明了该方法的有效性。

We proved that there exists a dense G (subscript δ) subset of the complete metric space consisting of the vector optimization problems satisfying some conditions ,and each problem in the dense G (subscript δ) subset has stable solution set, which generalized the corresponding results in the literature.

证明了满足一定条件的向量优化问题构成的完备度量空间中，存在一个稠密G集，在此稠密集中每个问题的解集都是稳定的，推广了文献中的相应结果。

This paper presents a new better searching method based on reordered vectors in complex field.

本文提出了一种在球半径范围内搜索向量的方法，即球译码方法，并在复域内提出一种基于重新排序的更好的搜索算法。

The central goal of this work is trying to generalize the above result to the Higgs version case, which should be helpful to the study of some question, say variants of the Kobayashi-Hitchin correspondence. The theorem to be proved here is the followingTheorem 02: Let M be a compact complex manifold of dimension m with a Hermitian standard metric g and let be a Higgs bundle over M.

本文的一个主要的目的是把上面的定理推广到E是—Higgs向量丛的情形；这一结果的意义在于在研究与Kobayashi-Hitchin correspondence相关的问题，如考虑Kobayashi-Hitchin correspondence的形变展现它的作用。

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。
