在本項目中，課題組在江蘇省境內的長江南瀏水域大橋初步選址處進行了如下試驗：海船及江輪船隊的「 z 」形試驗、旋迴圈試驗、沖程試驗以及船隊和海輪在橋區的會船試驗。Furthermore, the growth and the study of self - organized quantum dots structures become more and more important recently, and the application of self - organization technique become wider and wider in this thesis, we address the theory of film growth and the growth technique firstly more, the ways and characteristics of surface detection are prescribed we mainly report the growth process, results and discuss of self - organized quantum dots structures in the a12o3 substrates by s - k mode using ecr - mocvd, in the espd - u device the growth art of ain epilayer which is the preliminary foundation of self - organized gan / ain quantum dots structures, including the substrate cleaning, nitridation, the growth of buffer and the growth of gan and ain epilayer, is discussed we deliberately compare the test result of rheed xrd and afm and achieved the optimalized condition of ain at last we have successfully realized the growth of ain which is much smooth and better crystal quality moreover, we grow the self - organized gan / ain quantum dots structure in s - k mode because the limits of the heater temperature, we can not grow the atom - smooth epilayer of ain until now so we could not grow better quantum dots which have small diameter and big density but the self - organized quantum dots structures with better quality will be realized successfully if the substrate temperature is increased the thesis study belong to my tutor subject of national nature science foundation ( 69976008 )
本論文主要論述了在espd - u裝置上，採用電子迴旋共振等離子體增強mocvd （ ecr - pamocvd ）方法，在藍寶石襯底上通過s - k模式自組裝生長gan aln量子點結構的生長工藝、結果及討論。而重點分析了自組裝生長量子點之前的aln外延層生長工藝，包括襯底清洗、氮化、緩沖層的生長和gan 、 aln外延層的生長；通過高能電子衍射、 x射線衍射和原子力顯微鏡測試，並且對這些測試結果進行了詳細的比較研究，得出了較優化的工藝條件，生長出了晶質較好、表面較平整的aln外延層；進而採用s - k模式自組裝生長了gan aln量子點結構。由於實驗裝置加熱爐溫度的限制，我們沒有能夠生長出原子級平滑的aln外延層表面，因而沒能夠生長出密度比較大和直徑比較小的量子點。With the phenomena of dropping flow, backflow and secondary flow effected by circulation and surface curvature, the centrifugal pump ' s inner flow is very complicated 3d flow. therefore, the centrifugal pump inner flow is one of the difficult problems both in testing research and numeric computation
離心泵葉輪的內部流動是很復雜的三維紊流流動，同時由於受旋轉和葉片表面曲率的影響還拌有脫流、迴流及二次流的現象，是流體工程中較難的試驗研究和數值計算問題之一。The causes of poor inlet conditions such as backflows and vortices were analyzed, and some measures were made to ameliorate flow patterns and improve pump performance
通過模型試驗，分析了產生不利進水條件如迴流、旋渦的成因。由此提出了改善進水流態和改善機組運行性能的工程措施。The study comes from two projects - " the practical experiment of ship navigation and the simulation study of the shu - tong yangtze river road bridge " and " the study on the ship navigation of the yichang yangtze river railway bridge ". the data is from these practical experiment which includes z - model experiment of sea - going vessel and fleet, turning motion experiment, stroke experiment and encounter experiment between sea - going vessel and fleet. based on those, it calculates the track of the ship in the navigational waters according to the maneuverability and the response equation
本文結合導師課題， 「蘇通長江公路大橋船舶通航實船試驗及模擬研究」 ，和「宜萬鐵路宜昌長江鐵路大橋船舶通航問題研究」通過大量的實船試驗：海船及船隊的z型試驗、旋迴圈試驗、沖程試驗和海船及船隊在橋區的航行會船試驗等，以試驗的數據為依據進行理論分析、計算，然後根據船舶的操縱性能及操縱響應方程，計算船舶在橋區的運動要素及航跡。Standard specification format guide and test procedure for linear, single - axis, non - gyroscopic accelerometers
