計算機層析成像技術（簡稱ct ）是近幾十年來發展起來的一種新的無損檢測技術，具有檢測精度高、重建圖像無影像重迭、空間解析度和密度解析度高、可直接進行數字化處理等優點，現已被廣泛應用於航空、航天、機械、船舶、公安、海關、醫療等諸多領域。The apsp produced abroad is made by numerical controlled machine tool, which has noise level of 71db ( a ), the apsp produced in our country is made in the method of exploratory which has noise level of 73db ( a ) and 75db ( a ). in order to analyze the influence of stator curve to noise, the author used tri - coordinate measuring instrument to measured exactly the inside surface of stator and got the straddling point coordinate, and made curve fitting by using matlab as language and studied the fitting effect and then worked out the equation of stator transition curve in return seeking, then comparied this method with the standard style and made the conclusion : the equation of atator transiting curve of apsp made by numerical controlled machine tool is close to theorical 5 power curve standard style, but compared with it, the stator transiting curve of apsp produced in exploratory has a major error. combining the testing results of noise, one can know that the qualily of stator transition curve play an importance to t he noise of the pump
國外生產的汽車動力轉向泵是用數控機床加工的，其噪聲值為71db （ a ） ，國內生產的汽車動力轉向泵是用靠模方法加工的，其噪聲值分別為73db （ a ）和75db （ a ） ，為了分析定子曲線對泵的噪聲的影響，本人用三坐標測量儀對定子內表面進行精密測量，獲得定子內表面的離散點坐標，以matlab語言為工具對離散點進行曲線擬合，觀察擬合效果，然後，用回歸方法求出了定子過渡曲線的方程，並把該方程與理論方程標準型進行了比較，得出如下結論：用數控機床生產的汽車動力轉向泵的定子過渡曲線方程非常接近理論5次曲線標準型，而用靠模方法加工的汽車動力轉向泵的定子過渡曲線與理論5次曲線標準型相比較，則存在著較大的誤差，結合噪聲測試結果可知，定子過渡曲線的優劣，對泵的噪聲大小有著重要的影響。This paper is intended to discussion mainly focusing on the six points : the space layout of the garden ; the environmental design, exemplified nature and architecture, the outer and interior decorations in the overall composition ; the guiding principle of gardening, propagating the philosophical view of the confusions " marriage of the soul with nature " ; the dialectical thoughts value added to principle elements of gardens, such as inspired by nature, suitable measurement to local condition, showing and hiding, density and spacing, far and near, ideology guiding practice. . the gardening elements of unity and coherence of space which is mutually penetrated ; the gardening elements of space alignment, such as " views echo with one another, scenes appear at every turn " generally, from the angle of space designing, the paper is trying to provide materials data for understanding and studying for suzhou classical gardens, their imagination - inspiring atmosphere, superb artistry, rich cultural contents as well as gardening artistic characteristics
蘇州園林作為一門空間藝術具有獨特的魅力，作為文化載體，它積淀了豐厚的文化底蘊。本文主要就其庭院式的空間布局，建築與自然、室內與室外融為一體的環境設計；充滿人文精神的中國儒道「天人合一」的造園思想；因地置宜、順應自然、藏露疏密、虛實遠近、變化統一的辯證思維；相互滲透的空間層次，步移景移的時空間序列的表現手法等問題進行闡述。力求從蘇州園林空間設計的一個側面，去揭示其藝術的特徵、文化的內涵、造園的藝術規律。This technology has gathered attention not only from the decoration world but from a variety of fields where a high degree of precision is required, including in respect of machine parts that have to be free from even the slightest burr or clean room manufacturing

但在更多的場合中，構成計數過程的隨機變量未必相互獨立，而在各種相依關系中，負相協（ na ）和正相協（ pa ）是頗為常見的關系，這方面的研究和應用也是頗有價值的，本文的第二章證明了na列和pa列構成的更新計數過程的wald不等式和基本更新定理的一些初步結果；本文的第三章則是受到cheng和wang [ 8 ]的啟發，推廣了gut和steinebach [ 7 ] ）中的一些結論，從而得到了更新計數過程在一般吸引場下的精緻漸近性，對更新計數過程的收斂速度及極限狀態進行精緻的刻畫；最後，在有關na列的研究中，蘇淳，趙林成和王岳寶（ 1996 ） 》 [ 9 ] ，林正炎（ 1997 ） [ 10 ]已經證明了強平穩na列的部分和過程的弱收斂性，而乘積和是部分和的一般化，也是更一般的u統計量的特況，它與部分和有許多密切的聯系又有一些實質性的區別，因此，本文的第四章就將討論強平穩na列的乘積和過程的弱收斂性，因為計數過程也是一種部分和，也可以構成乘積和，這個結果為研究計數過程的弱收斂性作了一些準備。Our company is engaged in the production of the power tools to already have the history for 20 years, according to the production experience of many years, depend on the forerunner ' s equipments, professional talented person, produce to make power tools such as brands of " aosheng " " aokai " and " ronghu " the series ' product won the good opinion of the customer with the good quality, reasonable price, good sale and after - sales service
