A network with different topologic configurations is needed for flatness pattern recognition when strip width is changing, in this case the large learn assignment, slow convergence and local minimal in the network are observed, in order to solve these problems, first, a flatness pattern recognition GA BP network model with only 6 input and 3 output signals has been established based on Legendre orthodoxy polynomial, which is not only simple in structure but also is of clear physical meaning.

针对板宽变化时需要不同拓扑结构的神经网络才能完成板形模式识别任务，网络学习工作量大，网络存在收敛速度慢，易陷入局部极小等结构性能不佳的问题，首次建立了以勒让德正交多项式为基模式的只用 6个输入信号、3个输出信号的板形模式识别 GA- BP网络模型。

Based on the principle of PEC, surface cracks mainly affect the high frequency components and subsurface crack mainly affect the low frequency components, so the PEC signals can be analyzed in frequency domain, which can eliminate the influence of noises during measurement. A method of frequency spectrum separating point is proposed for flaw classification, which enhances the accuracy in classification of defects. The agreement between theory and experiment shows that the present method is valid and applicable.

通过对脉冲涡流的理论分析发现，表面裂纹主要影响脉冲频谱中的高频成分，而表面下裂纹主要影响脉冲频谱中的低频成分，因此可以将时域中易受噪声影响的脉冲涡流信号变换到频域分析，提出了"频谱分离点"的方法来对裂纹进行分类识别，提高了缺陷分类识别的正确率，理论分析和实验结果相一致，证明了该方法的正确性和有效性。

Some important properties of singular value vector of color face image were proved,and then it was extracted as algebraic feature and applied to color face recognition.

由于灰度图像易处理、灰度人脸图像库易获取的特点，大多数人脸识别方法都是基于灰度人脸图像的。

For a long time, it is a considerable, frequent and tiresome social activity to charge the consumers of public traffic service industry. It brings much incontinence for the consumers and this industry. The development and application of Information Card brings convenience for society existence. But, present Contact IC is lack of memory, security and duration. It is not suitable for the circumstance where the flow of bus-takers is. It's not easy to insert or take it out, and the read-and-write unit is weak. Radio Frequency Card is avoid above-mentioned shortcomings, so it has a bright future in the public traffic field and other service industries which inquire identification.

长期以来，公共交通服务行业的收费是一件最大量、最频繁、最琐碎的社会交往，给行业也给消费者带来诸多的问题，信息卡的开发应用给社会生活带来很多便利，目前，磁卡信息存储量少，保密性差，易损坏；IC卡在公交这样人员流动多，要求收费迅速且环境差的场合，这类卡的插入与取出就显得不方便，且读写器易损易脏，卡上的IC片也易损坏，射频卡克服了上述不足，因此在类似于公交系统这样的服务行业以及许多需要身份识别的场合，将有广阔的前景。

Indentifiable referents can be graded into three activations in terms of their cognitive difficulties: active, accessible and inactive referents; Unidentifiable referents can also be divided into two classes: anchored brand new referents and unanchored brand new referents according to whether the new referents can be anchored to a given noun.

可识别的范畴又可以根据其在认知上的难易程度区分为不同的活动状态；活跃的、可及的以及惰性的指称；不可识别的范畴也可以根据是否可以抛锚在某一名词性成分上而区分为可抛锚的和不可抛锚的崭新成分。

At the same time, chaotic pseudo-random sequences generator based on nonlinear dynamic filter security model are constructed to select the frequency hopping points for NDFT, improving the overall system security. 3、Aiming at replay attack of networks in the remote speaker recognition systems and distributed databases speaker recognition systems, a time-stamp watermarking method is brought, which quantizes magnitude coefficients of NDFT. The time-stamp watermarking is embedded into the user's voice sample/voice characteristic information to resist on the replay attack.

同时该类算法采用以非线性动力学滤波器为基础的伪随机序列发生器构造跳频序列来选择频率变换点集合，有效提高了系统的安全性。3、针对远程说话人识别系统以及数据库分布式说话人识别系统存在易受网络重放攻击的缺陷，本文给出一种基于非均匀傅立叶变换的&时间戳&水印量化算法，通过把时间戳水印嵌入待识别用户的语音样本/语音特征信息中，可以有效解决此类缺陷。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
