ABSTRACT Over the last few years much attention has been paid to the development of the technologies for Community Antenna Television networks. New technologies that can be used to support data communication service over CATV networks are developed. The new Hybrid Fiber Coaxial technology is spreading out rapidly in CATV networks. The usage of fiber provides large bandwidth and thus enables some new services to be delivered along with television broadcast. The CATV networks are expected to support diverse traffic with various service requirements.

随着新技术的不断发展，人们希望能够利用有线电视网络提供新的业务，HFC技术在有线电视网络中的广泛使用使得有线电视网络的带宽增加，也使得有线电视网络除电视广播外还能够提供其他的服务，这些服务的服务质量要求各不相同，如：数据服务要求低的丢失率，对延时的要求较低；而语音服务可容忍一定的丢失，但对延时、延时抖动有严格的要求，因此需要开发新的协议。

In terms of the positivity, compact support and normalization of B-spline basic function, the adjustment of the weights are accomplished locally and the output is simple. The results of the experiments show that the structure of the B-spline neurofuzzy-networks is clear and the training is more speedily than that of BP network.

在对刀具磨损状态进行监测过程中可以看出，B样条模糊神经网络内部的连接结构透明，可以很方便的根据实际需要调节网络结构，进行网络的优化来得到更加理想的诊断结果，同时证明了B样条模糊神经网络的训练速度优于BP网络。

Atypical problem is that our learners of WBI have no enough dynamics to study whenthey face the key composition of our WBI—online course. How to raise the learningdynamics by effective designing of online course is very important. In view of this, westudied how to improve learning dynamics of WBI learner by effective design of onlinecourse.

一个典型的问题就是，我们的网络学习者在面对我们网络教育的核心成分—网络课程时，积极性并不高，也就是说没有足够的动力去学习，由此看来研究如何通过对网络课程的有效设计来提高学习者的学习动力的问题有着相当重要的意义的。

The area user that radiate of cloud computation center enclothes needs to put forward his to want to use what network to serve only, the divine water in this pond helps you press require calculation, by want a service.

王涛打了个形象的比喻：我们可以把云计算中心看成一个虚拟化的资源池，池子里有各种网络计算资源、网络存储资源、网络带宽资源……云计算中心辐射覆盖的区域用户只需提出自己想要使用什么网络服务，这个池子里的神水就帮你按需计算、按需服务。

In computer network, there are several outstanding problems about TCP protocol and network management, such as the effect of TCP congest control, the technology of active queue management and its configuration, the inadaptability of TCP protocol in the coming high-speed network, the disability to fast application and deployment of new service and standards, the centralization of network management, etc.

在计算机网络中，目前的网络和TCP协议存在若干需要解决的问题，如TCP拥塞的有效控制、主动队列管理技术的选取和参数配置、当前TCP在高速网络下的不适应、新功能和新标准得不到快速应用和部署、网络的集中管理等。

Solution of network sale whole is after solid inflict, will change to enterprise whole generation sexual influence, culture of target of plan of configuration of the constituent structure of the company, personnel, sale, sale, company will as the network of sale whole solution carry out produce change, the clerk of industry tradition is likely no longer the demand of applicable network sale, and appear pressing to the demand of network sale personnel and technical personnel.

网络营销整体解决方案在实施以后，将对企业整体产生变革性的影响，公司的组织结构、人员配置、营销计划、营销目标、企业文化等都将随着网络营销整体解决方案的实施发生变化，企业传统的业务员可能不再适用网络营销的需求，而对网络营销人员和技术人员的需求就显得紧迫。

This paper makes use of improved BP algorithm compared to the traditional one and the new algorithm brings us higher speed in constringency and more preciseion in detection.

BP学习算法是神经网络中的一种重要的方法，反向传播网络是典型的前馈型网络，结构上它属于多层网络，分为输入层、隐层和输出层

With the high-speed development of Internet, network link rate are increasing contiguously, while network applications and services are raising a diversity trend. Thus, the network equipments (routers, etc.) have to meet the increasing requirements of services and performance, including support for differentiated services, and flexible service extension capability, etc.

随着Internet网络的飞速发展，网络传输速率不断提高，网络应用和服务逐渐多样化，这对路由器等网络设备的服务和性能提出了更高的要求，包括对区分性服务的支持以及灵活的服务扩展能力等。

The research of this paper is began with the analysis the geographic spatial character of the UPTN, and designs the UPTN data mode based on GIS. Then, based on the good exhibiting all kinds of topology of the UPTN, and combined with the technology evaluation standards of the UPTN, this paper builds the UPTN planning mathematic model, and puts forward the quantitative calculation of the UPTN evaluation standards based on GIS; brings forward the arithmetic of the optimal path of the UPTN based on the public traffic network storage structure; designs the bus lines grouping management model, and realizes the contradistinctive evaluation of the UPTN planning projects based on GIS.
