First, the article analyses the current situation of the Wide Band transmission optical network of Metro and put forward its target of next development. And it continues to talk about the key technology of the Wide Band transmission optical network of Metro: optical caber, MSTP, DWDM, RPR and make comparison with them. It offers the general plan of construction of the Wide Band transmission optical network of Metro.

首先，本文分析了目前宽带城域光传送网的现状，提出了下一代城域光传送网的发展目标，论述了城域光传送网中的主要关键技术：光纤直连、多业务传送平台、城域波分、弹性分组环，并对这几种技术进行了对比分析，提出了宽带城域光传送网总体建设方案。

This technique has good properties with security, imperceptibility and high hiding capacity of the hidden information.

4基于混沌序列的图像信息隐藏技术；将需要隐藏传送的图像以混沌噪声的形式加入到载体图像的时空变换谱中，接收者根据混沌序列的相关特性利用相应的混沌噪声来提取所隐藏的图像，该技术具有良好的信息安全性、不可觉察性和较高的隐藏容量。

So in chapter 2 of this dissertation, knowledge based vision systems are researched and a new knowledge based system framework is presented, where a blackboard scheduler for inference, based on message transfer is used.

因此本文对这个问题进行了系统的研究，提出了一个独具一格的基于知识的视觉系统框架，探讨了在计算机视觉系统中使用知识的途径，并且在其中使用了一种基于消息传送的黑板推理调度机制，克服了传统专家系统方法直接应用带来的一些问题。

Parallel transmission is faster than serial transmission and is widely used for transmission to printers.

并联传送较串联传送快，是传送往印字机的常用方法。参阅串联传送。

modulation is the transmission of information to be loaded onto a high-frequency signal in the process.amplitude modulation using signal to control the rate of carrier,with its linear modulation signal changes,and maintain the same carrier frequency.in the amplitude modulation,in accordance with the strength of signals in the spectrum of different components,it is divided into ordinary am (amplitude modulation standard am),with inhibition of bilateral carrier am,the carrier single sideband suppression am.the main difference is the different methods and structure of the spectrum.

摘 要：调制是将要传送的信息装载到某一高频信号上去的过程。振幅调制是用调制信号去控制载波的幅度，使其随调制信号线性变化，而保持载波的频率不变。在幅度调制中，根据已调信号的频谱分量不同，分为普通调幅、抑制载波的双边带调幅、抑制载波的单边带调幅。它们的主要区别是产生的方法和频谱结构不同。

The advantage is that the transmitted message can suffer from more errors caused by the noise in the communication channel. But after we perform the list-decoding algorithm on the received word, we get a list of codewords, and still don't know which is the correct one.

它的好处在於我们所传送的讯息可以承受更多来自於频道上的杂讯，不过在我们执行条列式演算法於所接收到的讯息后，我们可能得到很多个可能的结果，但却无法得知那一个是正确的原讯息。

If you cann't establish it in time, you will lost this part of market. China had spent two years on discussed about which need be first developed satellite transmission or cable. At last decision is cable transmission first according to the situation of a country. And descramble system adpot DVB-CI of Europe.

经过20年左右的探索，日本，欧洲，美国三个主要集团在HDTV的技术方面走着不同的路线。70年代开始日本就提出自己的HDTV方案，在此方案中，电视画面的垂直分解力提高到1125行，水平清晰度也相应提高，传送的信息量是NTSC制电视信号的5倍，同时把图像的宽高比从4：3扩展到16：9，使视野开阔，可获得较强的临场感觉。

DSPR (Dynamic Scanlines Post-Reallocation) algorithm changes the boundary of block assigned to each Transputer after each operation, so that the total number of strips needed to travel around the network can be decreased, and then decrease the cost of communication.

DSPR后动态扫描线分配算法的出法点是运算后根据运算参数动态地改变分配给处理单元的显示区域的边界，这样就可以减少需要传送的不属于自己区域内的条码数量，进而减少运算后的通信开销。

For a pump rotational speed, in fact there is a restriction depending on the process fluid, if the transmission is oil, pump can rotate at high speed, but when the fluid is a high viscosity of the polymer melt, such restrictions will be significantly reduced.

对于一台泵的转速，实际上是有限制的，这主要取决于工艺流体，如果传送的是油类，泵则能以很高的速度转动，但当流体是一种高粘度的聚合物熔体时，这种限制就会大幅度降低。

When two communicants and an adversary obtain correlated information through independent binary symmetric channels from a random source, and the adversary's channel is noisier than those of communicants, an authentication scheme which uses the correlated information between the two communicants is proposed based on the coding theory to make possible information theoretic secret key agreement against active attacks.

在无条件安全密钥协商中，假定通信双方通过相互独立的无记忆二元对称信道来接收二元对称信源所传送的信息作为初始信息，在这种条件下，本文提出了一种利用他们之间的初始相关信息对公共信道上的消息进行认证的具体方案，从而使得无条件安全密钥协商具有抗主动攻击的能力。

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。
