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 thesis introduces the research history of sonoluminescence, the properties and equipments of single-bubble sonoluminescence and the factors affecting the amount of light emission. Based on the experimental realization of SBSL, the experiment in this thesis is to confirm the coherence between the emitting frequency and the driving cycle of SL. Under this feature ,we established the programme of the experiment that measure the angular correlations in SBSL , built the experimental devices and conducted initial measurements .Then we got the conclusion that there is a presence of non-spherical symmetry in the process of SBSL .

本文介绍了声致发光的发展历史，对单泡发光的特性和实现声致发光的设备进行了描述，对影响发光强度的要素做了概述；并在实现单泡声致发光的基础上通过实验验证了单泡声致发光的发光频率与驱动超声频率具有一致性的特点，根据这一特点确立了声致发光角分布测量的实验方案，建立了实验装置，并进行了初步测量，得到在声致发光的过程中存在着非球形对称状态的结论。
