  1. It is the propose of this paper to develop a method to reduce the noise level of ma60 apu without more weighting and other infection on airplane. to accomplish this object, a new type of micro perforated absorber is used

    針對新舟60飛機apu本身的結構和環境特性，我們採用一種新興的環保型消聲材料-微穿孔板為上要吸聲結構完成降噪設計。
  2. Then analytical measurements of the noise were carried out on both of the turbines by means of modern acoustic apparatus and a conclusion has been found that the noise of the concentrated wind energy turbine is lower than the one of the ordinary wind energy turbine and the root of the trouble to cause noise chiefly originates from the turbine blade. besides, the result of analytical measurement also reveals that the power output both of the wind energy turbines will increase with the increase of the wind speed and unfortunately does the noise too. in order to lower the noise, a measures of noise reduction have been advanced that an active method is to develop a wind energy turbine run at a lower rating of wind speed while the passive method is to adopt a board drilled tiny holes, having established a sound technological basis for the development of a kind of wind energy turbine of low noise and high level in the world

    主要對濃縮風能型風力發電機在正常運轉時，噪聲產生的機理進行了理論分析研究，並與普通型風力發電機的噪聲進行了對比實驗分析；利用現代聲學測試手段對兩類機型進行測試與分析，得出濃縮風能型風力發電機產生噪聲低於普通型風力發電機和葉輪是風力發電機產生噪聲的主要部件的結論；通過對兩類機型的噪聲、輸出功率的測試，得出隨著風速的增加，兩類風力發電機的輸出功率在增加，產生的噪聲也在增加的結論；提出了進一步降低濃縮風能型風力發電機噪聲的措施，從主動降噪方面，研製低額定轉速的發電機；從被動降噪方面，採用微孔穿板的降噪結構；為研究開發一種國際上低噪聲、高水平的風力發電機打下了良好的技術基礎。
  3. Thus mechanical properties, heat resistance properties and solvent resistance properties of pu are greatly enhanced. crystal forms of composite materials, surfacial reactivity and adsorption assemble properties of zeolite are discussed in this paper by means of xrd, ftir and tg etc. the test results of xrd prove that mmt can be exfoliated into nanocomposites in pu / mmt, while zeolite keep its original crystal structure in pu / zeolite. the spectras of ftir prove that tdi can graft on the surface of the zeolite

    Xrd測試結果證實了有機蒙脫土在聚氨酷體系中能夠剝離成納米粒子，而聚氨醋/沸石分子篩復合材料中分子篩仍保持原來的晶型結構; ftir譜圖驗證了異氰酸酷（ tdi ）可太原理工大學碩士學位論文摘要與沸石分子篩表面的硅經基進行接枝反應形成穩定的化學鍵;而tg分析結果則進一步證實了分子篩的穿孔機理。
  4. That is, the partially penetrating sand drain ground is viewed as the double - layered ground, and its consolidation is analyzed with 1 - d consolidation theory, through the transformation from 3 - d consolidation to 1 - d consolidation in the region of sand drain. this can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under - lying soft layer. to the double - layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory

    然後，在充分考慮豎井區井阻、塗抹作用以及土體結構損傷破壞對固結影響的基礎上，將未打穿豎井地基合理地轉化為雙層地基，按一維固結理論計算，克服了傳統固結計算方法在豎井處理區與下臥層交界面處存在孔壓間斷的缺點；在此基礎上，從超載預壓法的基本原理出發，分析了雙層地基超載預壓固結、沉降機理，推導了多級等速加、卸載情況下雙層地基的固結計算公式，進一步完善了雙層地基固結理論。
