Firstly, the thesis introduced the development of VOD, the background and meaning of the program, then the author introduced the associated technology, mainly including the feature of multimedia, video compression technology and the protocols SCTP and RTP. Considering the ambulant of host , fluctuation of bandwidth,high error rate data in wireless networks ,the author proposed some QoS strategy in the wireless networks such as RTP/SCTP protocol stack , connection control of the server, two buffers in the client end point.,TFC congestion control algorithms ,etc. Based these strategies, the team members gives the software and hardware solution of the wireless video-on-demand system and gives the main modules design of the software system. The system adopted the C/S structure including two parts: server and client ,using the Mpeg-2 which is apporiate for networks as the supported format. The thesis emphatically researches on the video-serving module of the server and the sink module, player module of client.

本文首先介绍了视频点播系统的发展现状、课题的研究背景和意义；接着对课题的相关技术进行概述主要包括了多媒体特点，压缩技术，传输协议SCTP以及RTP；针对无线环境的节点移动性，带宽波动性，数据错误率高等三大特点，作者研究设计了无线环境下的QoS策略：RTP/SCTP协议栈，服务器准入控制机制，客户端双缓冲区，TFRC拥塞控制机制等；在这些策略的基础上设计了系统的软硬件解决方案，并对软件体系结构的主要模块进行了设计，整个视频点播系统采用C/S结构，由服务器，客户端2个部分组成，使用适合网络传输的流媒体格式Mpeg-2作为系统支持的格式，文中重点研究了服务器的视频服务模块以及客户端的接收模块和播放器模块，并利用线程池技术对系统进行实现。

This paper first discusses the nature of the kernel function,and then based on Riemannian geometry dependent on the data structure and method,an improved modifying kernel function is proposed,the kernel function is a simple and less calculation method,which conformal factor and support vector irrelevant,compared with previous studies overcomes the impact of support vector's number and distribution.

The entire Superstructure cross-section, except for traffic barrier, shall be considered to be placed at one time for purposes of determining support requirements and designing falsework girders for their stresses and deflections, except as follows: For concrete box girder bridges, the girder stems, diaphrams, crossbeams, and connected bottom slabs, if the stem wall is placed more than 5 days prior to the top slab, may be considered to be self supporting between falsework bents at the time the top slab is placed, provided that the distance between falsework bents does not exceed 4 times the depth of the portion of the girder placed in the preceding concrete placements.

整个上部结构截面除交通障碍，应被视为在一个确定的要求和支持他们的设计应力和挠度除，脚手架时间放在梁的目的如下：对于混凝土箱形梁桥，主梁茎，diaphrams，横梁，和连接底板，如果干墙放置超过5天前向顶板，可能被认为是自我支持之间的脚手架本茨当时顶端板放置，只要脚手架茨之间的距离不超过4倍，在前面的混凝土主梁部分存款放在深度。

This paper cutouts redundant code of Openswan, deletes NAT-T module, transplants IPv4 to IPv6 in both function interfaces and data sturctures, realizes modules in IPv6, such as Virtual Interface, Input, Output, SPD, SAD, ESP, IKEv1 and PF_KEYv2, finally accomplishes IPv6 VPN named v6swan.

本文对Openswan中的冗余代码进行了删减，并去掉了NAT-T的支持模块，对IPv4的相关接口和数据结构进行了向IPv6的迁移，实现了IPv6协议下的虚接口模块、进入和外出处理模块、SPD模块、SAD模块、ESP模块、IKEv1模块和PF_KEYv2模块，最终完成了支持IPv6的VPN软件v6swan。

Bull; To examine the financial and infrastructural support available for translation work—or should I say the lack of it; and also
