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。

Young patients with gait disturbance and short course of disease have good or excellent response to surgery, whereas patients with amentia or urine incontinence have poor response to surgery.

以步态不稳为主要症状，病程短、年轻，腰穿试验阳性者分流手术效果好，以痴呆和尿失禁为主要症状者分流效果差。

Therefore, we must reform the way the administrative law enforcement agencies assess, focusing on dereliction of duty rather than amercement.

为此，必须改革对行政执法机关的考核办法，变以罚没款为主要内容为对失职渎职为主要内容的考核。

We got the result: Bufo Raddei Strauch Tadpole (1) Bufo Raddei Strauch Tadpole was capable of lens regeneration, which originated from the epithelial cells at iris dorsal margin by dipigmentation.(2) Dipigmentation of Bufo Raddei Strauch by two methods: one was licked up by amoebocyte, the other one was flowed from the pigment cells.(3) In the lens regeneration cells of Bufo Raddei Strauch profiles of the mitochondria became complicated ribosome manifold, and the endoplasmic reticulum was cisternal dilation. During the process of deferentiation of lens fiber the cell nucleolus became little and chromatin shrinked.(4)The crystalline electrophoresis of Bufo Raddei Strauch Tadpole lens regeneration showed that during lens regeneration P-crystalline was expressed earliest then was γ-crystalline and α-crystallin, this result is consistent with newt.

结果表明：花背蟾蜍蝌蚪(1)具有晶状体再生的能力，其晶状体的再生来源于虹膜背缘的上皮细胞；(2)虹膜背缘去色素是转分化的前提，主要有两种方式：一种也是最主要的方式是在晶状体被摘除后虹膜外侧产生巨噬细胞，巨噬细胞吞噬虹膜色素上皮细胞中的色素颗粒；另一种方式是虹膜色素上皮细胞自身释放色素颗粒；(3)电镜观察发现虹膜色素上皮细胞转分化过程中线粒体有明显变化，核糖体增多，粗面内质网增多，晶状体纤维分化过程中细胞核逐渐凝聚；(4)SDS-PAGE电泳发现，花背蟾蜍蝌蚪晶状体再生中相关蛋白表达顺序与有尾类蝾螈相似，蛋白表达顺序依次是β-晶状体蛋白、γ-晶状体蛋白和α-晶状体蛋白，并且后两种蛋白几乎同时表达。

In addition to the principle pyroxene mineral, the secondary minerals of feicui are amphibole and feldspar.

RESULTS: There was plentiful COX2 protein in the cortex, the hippocampus, the dentate gyrus, the supraoptic nucleus, the amygdaloid nucleus, cerebellum and brain stem, and so on.

结果：在正常成年大鼠脑内COX2蛋白主要表达于皮层、海马、齿状回、视上核、杏仁核、小脑和脑干等部位，阳性细胞主要为神经元，神经胶质细胞染色很少。
