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。

Then two steganographic schemes with the ability of information authentication are designed by combining with Hash function and digital signature algorithm. Finally, the authentication security of the two schemes under active attacking istheoretical ratiocinated.(5) A public key steganographic system using gray image as the cover-object is developed.

设计了一种以灰度图像为隐秘载体的公钥隐秘通信方案，在嵌入相当大的数据量时，信息隐藏过程仍然较好地保持了原始图像的质量和统计特性，从理论和实验两方面对方案的安全性进行了分析。

Experiments proves that this algorithm not only give attention to the intensity of embedding watermarking but also guarantee the quality of image combining with human visual system better, and it has good robust under the image processing attacks such as cutting, filter, smoothing, sharping, and JPEG compression etc.

实验结果证明，本文算法兼顾了嵌入水印强度的同时更好的保证了图像质量，不仅能很好的结合人眼视觉系统，且对一般的图像处理如剪切、滤波、平滑、锐化和JPEG压缩，都具有较好的鲁棒性。

Xu Hong, also of the view that convertible bonds and exchangeable bonds is essentially no difference between bonds are embedded in a call to amend the Convertible options, the option to redeem, buy back options after the formation of derivative products.

徐虹还认为，可转换债券和可交换债券的债券之间没有本质上的区别是在调用嵌入修改敞篷选择，选择赎回，买回后形成的衍生产品的选择。

The experiment results indicated that the comprehensive interaction mode of Y with DNA might be that the dibenzofuran ring of Y intercalated into DNA base pairs and the benzene ring in side chain bind to DNA in the groove.

To accomplish the intelligent control of the three-axis numerical control system of the boring and milling machine tool based on IPC ,the research makes good use of the intelligence sport control card PCL-839 and PCLD-782/785 card to design the control system of the three-coordinate NC machine tool with the framework of embedding NC in PC.

为实现基于工控机 IPC 的三坐标印制电路板数控钻铣床的智能控制，研究运用PCL-839运动控制卡和信号输入输出卡PCLD-782/785，采用NC嵌入PC式结构设计该三坐标印制电路板数控机床的控制系统，以实现对该数控机床的控制。

The first principle based on the density functional theory and the nonequilibrium Green's function method are adopted to research the electronic transmission of a zigzag single wall carbon tube with an implanted Li atom.

运用基于第一性原理的密度泛函理论的非平衡格林函数方法对Li原子嵌入后的zigzag型单壁碳纳米管的电子输运性质进行了研究。

In his embedded-processes model of WM, Cowan (1999, 2001) uses the term focus of attention to refer to the core component of WM, and proposes that the focus of attention of WM and that of perception have the same span, which is a fixed number.

在嵌入加工模型中，Cowan (1999， 2001)将工作记忆的核心结构称为&注意焦点&，并假设工作记忆的注意焦点与知觉的注意焦点的容量限制是同一固定的数量。

It's my theory that a trained cataloger has a brain that's wired according to MARC, and it might also be said that AACR2 is embedded as well, though we rarely speak in terms of rule numbers (serialists are perhaps the exception that proves the rule).

我的 理论是，每一个训练有素的编目员尽管很少说的出第几条规则（连续出版编目员或许除外），但是都有一个被MARC电过的大脑，或者说AACR2嵌入脑中。

YCbCr colorized system is accord with the characteristic of HVS and used for JPEG system.

本文针对人类视觉系统的特点，以及实时采集图像常用的YCbCr分量视频信号，将水印信号嵌入载体的亮度分量的DCT系数中。

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