In case of high input dimension system model, taking norm of input vector as the input of wavelet network instead of using tensor product method to construct wavelet network ,which could solve the problems of high computation and curse of dimensionality.

在模型结构方面，对于多维输入输出系统建模，本文放弃选用传统的标量积确定小波基函数的方法，将输入矢量的范数作为小波网络基函数的输入变量，从而避免了高维输入所带来的可用小波基数量巨大和计算复杂的缺点。

The spectra, which were pretreated with the method of first derivative combined standard normal variate, were analyzed by principal component analysis.

将经一阶导数结合标准归一化处理后的光谱进行PCA降维，以前20个主成份（含原始光谱86.09%的特征信息）为输入变量，建立杂交稻种纯度鉴定的BP-ANN模型。

At present, many known results are obtained only on one dimensional functional space, and the research on high dimensional space is little, only the continuous solutions are discussed on RN, neither the differentiate solutions on RN nor the solutions on abstract space and manifold.

在一维情形下，所涉及的函数通常具有较好的性质比如单调性，逆映射导数的LipschitZ性(在研究光滑解时通常需考虑)等，而第il页摘要高维空间上函数则不具有这些好性质，因此，讨论高维空间上的迭代方程要求在方法上作一些改进和突破。

Msmodel is formulated with the relative displacement and the contact press direCtiyin the orthogonal coordinate syStem, without introducing the slip angle asvariable and transforming the variab1e to the polar coordinate system.

在工程实际中得到大量应用的二维摩擦接触问题迭代法，贴近力学直观，无须引入额外变量，无须计算导数矩阵，被工程界所熟悉。

In this paper,based on an improved orthogonal expansion in an clement , using the new idea of Ref.[3] ,a new error expression of n-degree Hermite finite element approximation to one-dimensional 4-degrec 2-point bounded problem and 2-degree ordinary differential problem, and then optimal order superconvergence for their first derivatives is obtained.

本文针对在改进的单元正交性估计的基础上，利用文[3]提出的新想法，得到一维四阶两点边值问题和二阶常微初值问题的n次赫米特有限元u_h∈C~1的新误差估计式，以及导数误差的最佳阶超收敛，并且两者有相同的超收敛结果。

Someone prominent had to take the fall for the atrocities committed by the Empire, but with Vader and Palp both already dead, only the GA in charge of the Core and that held off the Rebels for hours after the Death Star's destruction made a suitable showstopper.

某个身居高位的人士不得不为帝国的暴行负责。但由于维德和帕帕均已死亡，主管核心世界并在死星毁灭后继续抵抗叛军数小时的帝国元帅成为了表演高潮所需要的那个人。

According to Invamer-Gallup, a pollster, Mr Uribe's approval rating has remained steady at between 70% and 80% over the past year.

根据盖洛普调查，在过去数年里，乌里维的支持率稳固地保持在70%到80%之间。

The principal component method and the minor component method are recommended to reduce the computation of MNE and MPE respectively. Whether rank reduction conducted or not, STAP is always performed in a particular space which may be spanned or expressed by different sets of basis.

我们在第5章讨论了DFP结构上两种特征子空间降维方法，即最小功率特征对消和最小范数特征对消，这两种方法将权矢量约束在噪声子空间内，从而能够对消与噪声子空间正交的杂波分量。

Each record is a line with the following structure: Student last name, blank Student first name, blank Year of birth, blank Home form, blank Math, blank Set of marks with a blank after each of it English, blank Set of marks with a blank after each of it Science, blank Set of marks with a blank after each of it End of line character You have to write a program that reads information from the file into two-dimensional String array.

每个记录是一个符合结构如下：学生姓，空白学生名字空白出生年月，空白家乡，空白表格，空白数学空白的痕迹，与空白后的每个英语，空白的痕迹，与空白后，每年的资讯科技，空白的痕迹，与空白后，各该行结束字符你必须写程序，它可以读取资料，从档案成二维字符串数组。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
