With the progress of technology and developing of internet economy in the world, the broadband network becomes another hotspot in internet field when the foam of. com comes to almost nil. with the beginning of new thousand year, hot waves of the broad band surge throughout the country, sorts of investors come and make huge expenses in a constinuous stream to make a majority of marketing lot and lead up the position of broad band market. however, when the net circuity, which is based on huge numbers of cash, is facing the consumers, market really does not redound upon the investors inexpection
隨著技術的進步和網際網路經濟在全球范圍內的高速發展，寬帶網是繼? com "泡沫"破滅后網際網路產業的又一熱點。新千年開始，全國各地各類投資商紛紛拆巨資"跑馬圈地" ，以期在市場份額上搶占寬帶網市場領先地位，但是當這些"巨額現金'堆成'的網路線路面向用戶時，市場並沒有給投資商們預期的回報，寬帶網運營商不僅投資回收遙遙無期，還要繼續燒掉大量的現金去維持網路的正常運行，大批中小型寬帶網運營商苦苦支撐，有的甚至瀕臨破產。Recently, using solid clay brick is gradually prohibited, so the new wall material is required to fill up the new architecture. many sections research on this field, using fly ash to develop new building materials is the mostly adopted method, among the new building materials, fly ash foamed concrete is a noticeable one because of its outstanding merits such as light weight, heat preservation, sound insulation and good resisting earthquake. using fly ash to develop foamed concrete can not only become fly ash into resources, but also provide a new kind of building materials for the innovation of wall materials, which has good economy and society ben efits
近年來，由於墻改「禁實」政策的實施，市場急需新的墻體材料來填補新建築所需，許多單位相繼開展了各有關研究，綜合利用粉煤灰研製開發新型建材逐漸成為了主流，其中多孔混凝土特別是粉煤灰發泡混凝土，正以它突出的輕質、保溫、隔音、抗震效果好等優點，成為一種引人注目的建築材料，利用工業固體廢棄物粉煤灰研製發泡混凝土不僅能實現粉煤灰的資源化，而且還可為墻體材料的改革提供一種新型建築材料，具有較好的經濟效益和社會效益。The main work in this paper includes three parts : the theory research on partially - cavitating and super - cavitating axisymmetric bodies, the numerical computations and experimental investigations on partially - cavitation and super - cavitation on axisymmetric bodies. after finishing the study of theory and experiment on the partially - cavitation and super - cavitation for axisymmetric body, i use the potential flow theory to build the mathematical model on the partially - cavitation and super - cavitation for axisymmetric body. many cavity wake models, such as pressure recovery close model, riabouchinsky model and re - entrant jet model, are studied seriously
本文在深入研究了回轉體局部空化與超空化理論及實驗結果的基礎上，基於勢流理論，建立了回轉體局部空泡和超空泡流場的基本數學模型，通過對kinnas和fine 、 uhlman以及jiedang和gertkuiper等人基於二維水翼提出的壓力恢復閉合模型、鏡像板模型和回射流模型等空泡尾流模型進行了逐一的研究分析，發現其中的壓力恢復閉合模型較適用於模擬回轉體空泡尾部流場，並選用此空泡尾流模型作為求解回轉體空化流場正問題與逆問題的數學模型的組成部分。
