传输网络

In most database systems, plaintext travels on the communication channel, and human attack from the network occur easily.

通常的数据库系统其传输通道都是明文信道，在传输通道上的数据没有经过任何加密，很容易遭到来自网络的人为攻击。

The supply contracts do not require a cosφ equal to one. The reactive power is also used by the transmission lines owner for controlling the voltages. Reactive component of current adds to The loads current and increases the voltage drops across network impedances.

无功功率的一部分由用户端消耗掉，剩下的成为网络的负载，供应需求中并不要求功率因数角等于1，无功功率同样被传输线路运营者用来控制传输电压。

An improved scheduling method based on exponential division of deadline is presented after study on the problem of prevenient average division of deadline method in this paper.The paper also proves when the relative deadline of each node is too large,the schedular performance of messages transmission task using average division of deadline will be decreased by introducing notion of quantization cost.The new method solves the problem well,and digital simulation validate the new method.

摘 要：针对平均分区的EDF算法在CAN总线中的应用出现的问题，本文提出了一种改进的基于指数分区的EDF算法，并通过引入量化误差的概念，推导证明当CAN网络中各节点相对截至期分布时间过大时，平均分区的EDF算法会导致CAN总线中信息传输任务可调度性的下降，而基于指数分区的EDF算法保证了信息传输任务的实时性，仿真试验验证了算法的有效性。

A transport protocol that provides for the SCSI protocol to be carried over a TCP based IP network.

一种能够使SCSI协议在基于TCP的IP网络上传输的传输协议。

After studying the existing secure communication scheme,a new scheme is designed and realized.

通过对现有安全传输方案研究，设计并实现了一种新的网络安全传输方案。

In DTN transmission agreement, if destination route was not found, data bag won't be missing, name a person for a particular job of every network division carries message until realize safety to transmit with another node, this and basketball game are similar, the player can accuse a ball to also can pass a ball, till shoot a basket.

在DTN传输协议中，如果目的路径没有找到，数据包不会丢失，每个网络节点将保持信息直到与另一个节点实现安全传输，这与篮球比赛类似，球员可以控球也可以传球，直至投篮。

Including : 1, wiring system : as wiring harnesses box center will signal cables distribution to the appropriate location, and through wiring boxes for the convenience of control and management ;2, transmission conductors : weak electricity more types of signal wire, coaxial cable, UTP, as audio transmission lines, transmission lines for the transmission rate is the main signal decay and ;3, terminals : the main categories of information, including panels ;4, various information appliances : such appliances will have a receiving or sending information available, including television, computers, network appliances.

其中包括：1、布线系统：以配线箱作为配线中心，将信号线缆分布至合适的位置，并能通过配线箱进行方便的控制和管理；2、传输导线：弱电信号导线种类较多，有同轴电缆、双绞线、视音频传输线等，对传输线的要求主要是传输速率以及信号衰减；3、终端设备：主要包括各种信息类面板；4、各类信息家电：此类家电都带有信息接收或发送端口，包括电视、电脑、网络家电等。

A standard developed to meet the requirements of portable consumer imaging and multimedia applications — what the IEEE refers to as the standard for High Rate Wireless Personal Area Networks.(The IEEE defines High Rate as 20 Mbps or better.) It is based on a centralized and connection-oriented ad-hoc networking topology. The standard also supports peer-to-peer connectivity and isochronous and asynchronous data.

802.15.3标准的开发主要用于满足便携式用户成像和多媒体应用的需求。802.15.3标准也就是IEEE所指的高速无线个人局域网标准，IEEE规定其传输速率不低于20Mbps.802.15.3标准建立在一个集中的，面向连接的特别的网络拓扑基础，支持对等连接和同步、异步数据传输。

In the network correspondence, the synchro communication gets hold of far-ranging grant therewith supernal efficiency and rate of transmission.

摘要在网络通信中，同步通信以其高的传输效率和传输速度得到了广泛的应用。

This thesis introduces the whole project and each module on exploitation, for instance:net transmission module,MPEG4 image serve module,database module, history track record module,sound talk-back module and so on .

本文介绍了本系统的方案设计以及各个模块的开发实现，其中包括：网络传输模块、MPEG4图像服务模块、数据库模块、历史记录模块以及声音对讲模块等，设计方案是一套专门面向电力行业的变电站遥视警戒系统，目前已成功的运用于苏州电力的变电站远程视频监控中，实现了变电站视频、音频、数据的远程传输、控制及记录。

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。
