針對無連接和面向連接的各種復雜網路環境下，通信頻帶資源緊張，音頻傳輸帶寬有限且復雜多變，而各種音頻數據又日益增多的局面，本文研究小波分析在信號處理方面的數學依據和在數據壓縮方面的實際意義，在前人不斷工作的基礎上，提出了一種優化小波包變換編碼方案用於音頻數據的壓縮演算法，兼考慮了編碼效率、多碼率和壓縮時延多個方面，並在matlab環境下做了模擬實驗，對各種音頻信號及多種小波函數做了模擬結果比較，實驗結果證明該演算法可以在一定計算復雜度下可以很好地改進壓縮效果，達到多碼率下實現實時編解碼的過程，在高速dsp晶元等硬體設備支持下，可以有效應用於實際復雜多變信源編碼。As it ' s proprietary, a large numbers of bibliography resource ca n ' t be provided to common readers of internet. along with the development of network technology, it has a instancy need to conversion marc format to the information that the browser can recognize. the language xml not only can expresses the metadata, but also can show the content of data. lt can provide individuation page layout
Marc格式是目前圖書館館藏資源的主要表示格式，由於其專用性，使得目前大量的書目資源無法通過一般的搜索引擎向internet用戶提供，隨著網路技術的不斷發展，迫切需要將marc格式的數據轉換成常用瀏覽器所能識別的信息，為大眾提供服務，可擴展標記語言xml不僅可以表達元數據，而且可以揭示數據的內容，提供個性化的頁面顯示，用xml語言對marc數據進行描述是解決這一問題的有效途徑，文章提供了marc數據的xml表示方法和實現途徑。In tranditional ip network, only the “ best effort ” service is provided, but the quality of service can not be guaranteed. though the interserv, deffserv and mpls are presented afterward to guarantee the qos for the ip network. but as a layer network, the realization of the qos function need span different layers ( such as rsvp protocol ) in the ip network, which may result in the function iterance and chaos
多媒體和實時業務的出現要求網路能夠提供足夠的qos保證，在傳統的ip網路中只能提供「盡量傳輸」的服務而不能保證服務質量，后來提出的綜合服務模型（ interserv ）以及區分服務模型（ deffserv ）以及mpls技術保證了ip網路上的服務質量，但由於ip網路是層次結構的網路，因此對qos的支持需要跨層（如rsvp協議） ，這就可能引起功能的重復和混亂，而微通信元系統是無層次結構的網路系統，就克服了這些的問題，變得簡單，效率更高。Research of this paper opens out enclosing the subject that m & as and reconstruction of public companies can help to realize resource collocating of securities market, advance quality of public companies, and promote the optimization of structure and function of stated - owned economy. the paper researches how to change the financial and speculative reconstruction at present to the strategic and material reconstruction aftertime. firstly, the author proves the feasibility of m & as and reconstruction that conduces to advance management efficiency of companies and efficiency of securities market in theory, and emphasizes on some conceptions which have certain differences between westward m & as and reconstruction market and ours
西方的並購重組理論為我們提供了一定的思考的角度，其中比較有代表性的有效率理論，從管理、經營、財務的協同效應和多元化經營、戰略重組等方面解釋了並購重組對改善企業經營管理的可能性；代理問題理論，把並購重組作為解決企業委託代理問題的一個外部機制，即當由於公司管理層的無效率或代理問題而導致公司經營管理業績不佳的時候，公司就可能面臨著被收購的威脅；信息與信號理論，認為並購重組信息向市場傳遞了有關公司管理、股票價值、資本結構等方面的信息，從而引起公司的市場價值被重新評估，導致股價波動。In improved uep scheme, the syntax elements belonged to luminance parts and chrominance parts was reassigned to different data partitions. those packets containing syntax elements belonged to luminance parts were got error protection at high level so as to guarantee their correctness during transmitting in error - prone network. simulation has shown that using proposed scheme, the packing tradeoff is decreased 8240 bytes in error - free channel and also the output bits and bit rate of coded video stream are decreased 2. 70kbits and 0. 33 kbps respectively
模擬實驗表明，本方案能在無噪通道中有效降低編碼器端8240位元組的打包開銷和2 . 70kbit的輸出比特數以及0 . 33kbps的比特率，而在有噪通道中可使解碼輸出重構視頻圖像的視覺質量得到一定程度的提高，亮度分量峰值信噪比可增加近1db 。Such a reform can bring various effect ; the operation is becoming easier ; the information transmitting is enhancing, the invalid work is reducing ; the students " skill is fostering and the level of their writing is improving
