Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers. The coupling of hydraulic model with water quality model is built up. The combined model was applied to a large complicated river networks with numerical hydraulic structure which influenced by strong tide, storm and heave rain. Visualization of computational results is realized by means of MapInfo, which displays the computational results in fast, convenient and accurate way.

水力模型以描述河道洪水波运动的Saint-Venant方程组为基础，用Newton-Raphson方法直接求解按Preissmann加权四点格式进行离散所得的非线性代数方程组，提出了压缩存贮形式的Gauss列主元消去法并对数值解的收敛性进行了讨论；将支流流量的松弛迭代方法从树状河系推广到了环状河网，使任意复杂河网水力计算的问题都可化为一系列的单一河道的水力计算问题；建立了水力模型与水质模型的联接，初步应用于既有洪水、暴雨、强潮等综合影响，又存在多种水工建筑物及水力调度问题的大型复杂河网中的非恒定流水力、水质计算问题；利用MapInfo对计算结果的可视化进行了研究，有利于决策者快速、方便、准确地作出决策。

It has effective interlaced signal encode algorithm and wide bit rate scope. MPEG2 can represent interlaced and progressive video sequence, and it is widely used in DVD, HDTV and digital satellite TV.

MPEG2是视频和音频信号数据压缩国际标准MPEG1的扩展，直接面向高数据率的广播格式，提供了有效的隔行视频信号编／解码算法，支持宽范围的比特率。

When you do use sound, Macromedia Flash willcompress music into small MP3 files and even stream it.

当你使用声音时，flash会压缩声音文件成小的mp3格式并且流式输出他。

Furthermore, we propose and implement multilevel circuit partitioner. The achievements of the dissertation are as follows: During the coarsening phase, we propose thecore-sorted heavy-edge matching algorithm and give its details based on the compressed storage format of graph.

本文主要的工作和创新点有以下四个方面：在多水平粗化阶段提出了一种基于核排序的重边匹配算法，给出了基于图压缩存储格式的算法实现细节。

Recently, the digital multimedia is becoming a major issue because of it has some significant properties such as high compression rate, noise reduction, secrecy, and pocketable. Therefore, the most data of the multimedia are presented with digital format.

近年来，由於数位科技的进步与多媒体技术的发展，数位化的资料具有高资料压缩率、高抑制杂讯能力、保密性佳与可携性等优势，因此目前大部分的多媒体资料皆改由位格式呈现。

MPEG-2 gradually becomes dominant in NLEs area. At present in order to solve the problem of net band, many manufacturers adopt compression format of MPEG-4 to pre-edit and browse, in this way, they can make the software coding in lOOkb/s GIF to frame accuracy editing.

为了解决网络带宽问题，目前不少厂家采用MPEG-4压缩方式进行粗编和浏览，现在可做到在1OOkb／s的CIF格式图像上软件编码，精确到帧编辑。
