总结了多层前向神经网络的结构设计方法，然后提出了一种新的小波神经网络构造算法。

According to the input of sample set, a function set of multiresolution wavelet node was obtained and the output vectors of each node were computed.

摘 要：依据训练数据集，构造多分辨率的小波节点库，再根据输入给出小波节点的输出向量。

After extending the definition of tangent distance,we extract the directions of variance of sample sets using Singular Value Decomposition based onthe original image, and use them as the tangent vectors of training sample sets.

本文把切线距离的概念进行了进一步的延伸，在原始图像的基础上，用奇异值分解方法直接提取样本集合中所包含变化的方向，作为训练样本的切线向量。

The definition of work suggests a third process of vector algebra, namely, scalar multiplication of two vectors

功的定义用到矢量代数的第三种运算，即两个矢量的标积。

Historically, these have been difficult for a designer to work with, though, because without a "translator" like Adobe Type Manager (turns the vectors into pixels so the monitor can show them to you) there was no way to accurately and smoothly display the font on screen.

从历史角度来说，设计师使用起来并不方便，因为缺乏一个象Adobe Type Manager那样的"翻译"来将矢量格式转化成显示器能够显示的像素，所以就不可能在屏幕上精确和平滑的显示出来。

Objective:To construct suitable vectors for the secretory expression of heterologous proteins in Pichia pastoris.

目的：构建合适的载体用于外源基因在巴斯德毕赤酵母中的正确分泌表达。

This paper mainly deals with invariant subspaces and cyclic vectors of certain diagonal operators on a separable Hilbert space. In this case, a complete characterization is given.

考虑一般对角算子的不变子空间是非常困难的，本文主要研究Hilbert空间上一类对角算子的不变子空间和循环向量，给出了这类算子不变子空间和循环向量的完整刻画。

This chapter clarifies the nested relationship between the matrix family of unitary, orthogonal, Givens, Householder, permutation, and row or column symmetric matrices. A precise correspondence of the singular values and singular vectors between the unitary-symmetric matrix and its mother matrix is derived and proved (hence a fast algorithm of singular value decomposition for unitary-symmetric matrix is straightforwardly obtained), and the corresponding perturbation bound is provided.

该章揭示了酉对称矩阵、正交对称矩阵、 Givens 对称矩阵、 Householder 对称矩阵、置换对称矩阵和行对称矩阵之间的逐级包含关系；推导并证明了，酉对称矩阵的奇异值和奇异向量与母矩阵的奇异值和奇异向量之间的定量关系，据此可得酉对称矩阵奇异值分解的快速算法；给出并证明了摄动矩阵的摄动界。

The first several left singular vectors of the decomposed matrix are used to calculate contribution of each sensor candidate.

用分解后的前几个左奇异向量计算每一个自由度对于结构模态的贡献。

Latent semantic index LSIis a new algebraic model for information retrieval, which maps documents and queries vectors into a lower dimensional space by singular value decomposition, so that the inherent vagueness associated with a retrieval process based on keyword sets is considerably reduced and semantic association among the documents is highlighted consequently.

隐含语义索引是一种新型的信息检索模型，它通过奇异值分解，将词向量和文档向量投影到一个低雏空间，消减了词和文档之间的语义模糊度，使得文档之间的语义关系更为明晰。

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。
