傾斜後效 的英文怎麼說
中文拼音 [qīngxiéhòuxiào]
傾斜後效
英文
tilt after effect-
The thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed channel are measured by using infrared camera and then the impingement cooling heat transfer coefficients are deduced. the effects of flow and geometry parameters on convective heat coefficients are obtained. the results show that : for a single row normal impingement, the impingement cooling effectiveness is enhanced with the increase of impinging reynolds number or the decrease of hole space to diameter ratio, and the best effectiveness is achieved under the jet - to - surface spacing equals to 2 ; when the jet is oblique to the confined wall, the cooling effectiveness is weaken especially under the jet - to - surface spacing ratio is greater than 2 ; for double rows normal impingement cooling, the cooling effectiveness of rear row jet is weaker than the front row under lower impinging reynolds number or bigger jet - to - surface spacing
對于單排垂直射流，沖擊冷卻效果隨射流雷諾數的增加、孔間距與直徑比的減小而得到提高，沖擊間距比為2時換熱效果最好;沖擊孔中心線向通道封閉一側傾斜后，射流沖擊冷卻的范圍變窄，當沖擊間距比大於2時駐點區的對流換熱能力明顯降低;對于雙排沖擊射流，孔排間距與直徑比的增加使沖擊冷卻范圍變大，但在兩排孔之間區域的對流換熱系數有所下降;在較小的沖擊射流雷諾數和較大的沖擊間距比下，後排射流的沖擊換熱效果要遜於前排射流。Then, a cfd model of the labyrinth seal is established, several seal models are numerical simulated in fluent, and the regularity of affections of the parameters, such as discharge pressure, shape of teeth and cavities, cavity inclination, labyrinth clearance, rotate speed and numbers of seal teeth are discussed in detail
最後論文建立了迷宮密封的cfd模型，採用fluent軟體詳細地分析了齒形、間隙、腔形、齒數、齒傾斜角以及換熱等因素對迷宮密封效果的影響，為迷宮式壓縮機的國產化設計和性能優化提供了理論依據。Firstly, in the magnetic field varying from 0mt to 1200mt, we have tested the faraday rotation angle of the three kinds of crystals. at different aspects such as nonlinear aspects, the influence on rotation angle caused by coating the crystals and inclining them the experiment has been finished. and the experiment achieved the following results : 1
從faraday效應的磁致非線性特徵、鍍增透膜對faraday旋光角的影響、晶體傾斜對旋光角的影響三個有關旋光角的方面進行了實驗，得出： 1 、 faraday旋轉隨外磁場變化的非線性變化曲線； 2 、鍍增透膜前後晶體旋光角的變化比較曲線； 3 、晶體傾斜前後旋光角變化比較曲線。If the racquet is tilted or laid back at contact you do not get this brushing effect
如果網拍在接觸球時是傾斜的或者被向後地放置，你不會得到這一梳刷的效果。The achievement of this paper exists in follows : ( l ) to refer to previous framework on investment structure, study investment structure by regarding west - china as a whole, fill up the academic blank on investment structure in west - china. ( 2 ) to find out the problems on investment gross, structure of main body of investment, industry structure of investment, technical structure of investment, accommodation structure of investment and etc in west - china. to establish counter - measures accordingly. ( 3 ) to advance the suggestions about improving investment structure in west - china, such as " balance development and focus on emphases ", " dynamic adjustment ", " promoting technical progress " and " paying attention to comparative benefits "
本文的研究成果和創新主要在於:參照前人對地區投資結構的研究框架，把西部開發所劃定的十二個省級行政區劃地理范圍作為一個整體來進行這種投資結構的系統性研究，填補了理論界關于西部地區投資結構研究的空白，找出了西部地區在投資總量、投資主體結構、投資技術結構、投資產業結構、投資供給結構等方面存在的問題，並且制定了較為可行的具體措施，最後提出了「均衡發展、重點傾斜氣「動態調整」 、 「推動技術進步」 、 「注重比較效益」等四條優化西部地區投資結構的建議。分享友人
