传输网络

Principle: the direct use of network base station signals for data exchange, through the fiber-optic network and satellite network transmission lines.

原理：直接利用网络基站发出的信号进行数据交换，通过光纤网络和卫星网络进行干线传输。

Multicast is a kind of streaming transmission technology to broadcast multimedia data on network.

多媒体网络组播是一种基于网络的，播放多媒体信息的网络传输流技术。

In addition, the network throughputs are analyzed with the channel transfer protocol CSMA. The computer simulation of the system model is performed.

在组网后规定网络通信路由的情况下，利用CSMA作为信道传输协议，对网络中节点之间通信的吞吐率进行了分析，在给定节点平均通信业务量的条件下，分析了整个网络的吞吐率，推导了模型参数的估值公式。

A primary goal in the design of wireless sensor networks is lifetime maximization,constrained by the energy capacity of batteries.So a critical issue is to strategically deploy an appropriate number of aggregators so as to minimize the amount of energy consumed by transporting the data.

无线传感器网络设计的一个主要目标就是最大化网络生命期，因此需要研究如何部署适当数量的簇头节点达到最小化整个网络节点数据传输能量消耗。

The right of divulgation in the internet, means that an author has the right to determinate whether to issue his works publicly by means of the internet, and also may comprehend one kind of static fight that the right man owns by law,but the fight of transmission in the internet is a right that the author and related right men carl enjoy with cable or wireless means to supply their works to the public,causes the public to obtain the works in the fixed time and site.such reflection is the actual condition the authors had achieved the right of divulgation.

网络发表权是指作者决定是否将其作品通过网络公之于众的权利，所反映的是一种待实现状态，也可以理解为是权利人依法享有的一种静态性权利；而网络传输权是指著作权及相关权利人享有以有线或者无线方式向公众提供作品，使公众可以在其个人选定的时间和地点获得作品的权利，其反映的是作者实现发表权的现实状态。

The communication component try a new method, hide the complex of data transfer process, task management, communication management, data management, and implement the communication component in OOP, highlight on the atomic, support data continue transfer, data compress, decrease the press of network, so, the communication component is more duplicative, extend, flexible.

其中，网络通讯部件尝试从新的角度出发，封装了网络数据传输复杂过程为任务管理器，通讯管理器，数据管理器等三个部分，并以面向对象的设计方法实现该模块，重点突出了其事务原子性，增加断点续传能力，并支持数据压缩，减少网络负载，因此，该通讯系统具有良好的可复用性、可扩展性和灵活性。

The stability problems are analyzed and discussed. The optimal control problem is formulated to determine the necessary conditions for optimality in networks. Three theorems about the properties of the steady state-costate solution in Hamilton function are confirmed leading to the natrual meaning and the optimal policy which can be implemented in practice. In chapter Ⅴ, the methods for nonstationary simulation of computer networks are discussed.

第四章表述了计算机通信网动态特性研究的主要数字方法；提出了排队与随机存取机制、网络链路传输和节点分流的状态空间模型，并作了稳定性研究；应用最优控制理论得到网络最优控制的必要条件，证明了哈密尔顿函数协状态变量的稳定解性质，据此研究分析了网络最优控制的本质意义及实现途径，并给出计算及建模实例。

This is due to malicious attackers to steal, modify the network transmission of information through the Internet posing as legitimate users of illegal access to the remote host, access to stored on the host of confidential information, or take up network resources and prevent other users and so on.

这是由于怀有恶意的攻击者窃者、修改网络上传输的信息，通过网络冒充合法用户非法进入远程主机，获取存储在主机中的机密信息，或者占用网络资源，阻止其他用户使用等。

Newcharacteristics of supply include: the transmission of Net-commodity I through intemet--intemet supply, and the direct supply caused by the reduction in the links of commodity circulation. Because of its unique cost structure, the supply of Net-commodity I is that of zero marginal cost and its supply curve is level. What is corresponding with demand expression is mass customization, and thus leading to the integration of supply and demand.

在供给上的新特点包括：网络商品Ⅰ通过网络的传输——网络化供给；流通环节减少导致的直接化供给；由于独特的成本结构，网络商品Ⅰ的供给是零边际成本的供给，它的供给曲线是水平的；与需求的表达相对应的是定制化供给，由此也导致了供给和需求一体化的趋势。

Major obstacles are raised during legal proceedings over network virtual properties, because of the difficulties in retrieving and solidifying evidences over network in real time, which, in term, are due to the mobility, undeterminability, and modifiability of digital information transferred through networks.

由于网络传输中数字信息的流动性、不确定性和易删改性，使得网络证据难以即时取得、难以固定。这一特征成为影响网络虚拟财产纠纷诉讼的主要障碍。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
