A data dessimination mechanism based on confidence coefficient Energy of nodes in a WSN is spent mostly on delivering the packets. In order to decrease the number of packets, while not increase the time delay, a model of data dissemination based on confidence coefficient is presented.

4提出了一种基于置信因子的数据分发机制无线传感器网络中节点的能量大部分用来传输数据，为减少数据的传输量，同时不增加数据包的延迟，提出了基于置信因子的数据分发概念，并设计了一种基于置信因子的发送退避策略和传输过滤器。

It is important to transmit the images in the magazines to every printing distributer immediately and images take up the net bandwidth less.It will increase net transmission action in the same net bandwidth.The paper aims at the upwards problem.

及时有效地把报刊杂志文字和图像传输到全国各地的印刷分点就显得额外的重要，并且传输的文字和图像占据的网络带宽小。

However, due to the constraint and diversity of computing resources on mobile devices as well as dithered bandwidth and instability of wireless networks, traditional video coding techniques can not be directly used in mobile environment.

然而，由于移动设备计算资源的限制性和异构性，以及无线网络带宽的波动性和传输的不稳定性，导致基于Internet上的视频编码和传输技术不能直接有效的应用于移动环境。

Under the hitless working condition, it is applicable to meet the PCM framing 2 M circuit recommended by ITU-T G.703 and delay the transmission by signals along the transmission path of the network for time adjustment and completion of switching so that the quality of the automatic protection switching is superior hard-switching (generally known as damaged switching).

在无损伤工作方式时，适用于满足ITU-T G.703建议的PCM成帧2M电路，通过对信号沿网络中不同路径传输时所产生的传输延时进行时间调整来完成倒换，自动保护倒换的质量明显优于硬倒换。

Article 17 The bank shall use proper encryption technology and measures, so as to identify users of the online banking services and the authorization thereof, ensure the confidentiality and authenticity of the data transmitted in online transactions, and accomplish the integrity of information transmitted on line and the irrevocability of the transactions.

第十七条银行应采用合适的加密技术和措施，以确认网上银行业务用户身份和授权，保证网上交易数据传输的保密性、真实性，保证通过网络传输信息的完整性和交易的不可否认性。

In order to provide this kind of service,the wireless network must be able to support the different data transmission speed,in other words,in the room,outdoor and in the motion environment can support 2Mbps separately (a megabyte/each second),384kbps (a kilobyte/each second) as well as the 144kbps transmission fast.

为了提供这种服务，无线网络必须能够支持不同的数据传输速度，也就是说在室内、室外和移动的环境中能够分别支持2Mbps、384kbps以及144kbps的传输速度。

It is superior to automatic meter reading system of power line carrier system, it is characterized by features which are not to build new communication network, more accuracy transmitting kilowatt-hour meter data, and no restriction on region, space,time and distance, and realize point-to-multipoint data transmission.

该系统优于目前电力行业广泛使用的载波方式自动抄表系统，其特点是：不需另建新的网络传输系统，数据传送实时性强，不受地域、空间、距离、时间的限制，可进行一点对多点的数据传输。

Clock recovery is the key for synchronization of MPEG-2 transportation over network. The PCR delay jitter is the main issue for clock recovery by PLL system.

时钟恢复是MPEG—2在网络上传输的同步关键，MPEG—2的标准建议采用PLL在本地恢复编码器的时钟，而PCR传输延迟抖动是PLL进行时钟恢复的主要问题。

Domestic and overseas new technologies about conference system based on digital network in recent years are introduced, namely digital processing and transmission, high-frequency and infrared transmission, NOMA, mute corresponding interaction, camera shot auto tracking, video conference system, interactive digital board, multi-assembly-room system control, and audio-video and lighting network centralized control platform technology.

着重介绍近年国内外基于数字网络的会议系统新技术如数字处理和传输、高频和红外传输、NOMA、哑声对应互动、摄像自动跟踪、会议电视、交互数字白板以及多会议室系统控制和声像灯光网络化集控平台等技术，并举出典型的应用实例。

If two parties want to sign a contract C over a communication network, they must "simultaneously" exchange their commitments to C Since simultaneous exchange is usually impossible in practice, protocols are needed to approximate simultaneity by exchange partial commitments in a piece by piece manner The party of secondly sending commitments may have a slight advantage; a "fair" protocol must keep this advantage within acceptable limits The protocol for signing a contract is improved based on the research result of secure multiparty computation In this protocol, the parties obliviously transfer the signed bit and the committed bit; the other parties can prove the validity of this bit based on the confirming sub protocol, but he can't gain more information about the whole signature by accumulating the signed bit or the committed bit After the parties exchange the whole signed information, they declare the commitment about the signature respectively, and gain the whole signature of the other party At this moment, the party doesn't care about the advance quit of the other party, because he has gained the whole signed information Finally, it is proved that this protocol is quit fairness

作者中文名：曲亚东；侯紫峰；韦卫摘要：在网络环境中解决合同签订问题需要保证信息交换的同时性，以前提出的协议都会给第2个发送者部分计算特权，利用不经意传输协议则可以解决这个问题。在协议执行过程中，参与者将合同的签名位以及他对签名位的承诺不经意传输给对方，对方可以利用验证子协议证明该位的有效性，但是他却不能通过位交换次数的增加获取更多的完整签名的信息；在完成签名位的交换之后，参与者分别宣布承诺，并得到对方对合同的完整签名；在宣布承诺时，协议参与者已经获得全部的签名内容，要么是签名位，要么是对方对该位的承诺，因此参与者并不需要担心对方提前终止协议。在文章的最后利用多方安全计算的结论证明了该协议满足终止公平性。

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。
