In the northern southern hemisphere, the air around an anticyclone moves in a clockwise counterclockwise direction
在北南半球,反氣旋附近的氣流是順時針逆時針方向運行的。In the northern ( southern ) hemisphere, the air around an anticyclone moves in a clockwise ( counterclockwise ) direction
在北(南)半球,反氣旋附近的氣流是順時針(逆時針)方向運行的。Through the research on the development character of overthrust fault, we analyzed its sealing mechanism. we also established evaluation standard and method of fault sealing ability through the following two simulation experiment : experiment on the quantitative relationship between property of fracture zone filler and fault sealing ability ; experiment on the deformation character of cream shale. based on these work, we evaluated sealing ability of overthrust faults on several typical structure in kuche depression
本文通過逆掩斷層發育特徵研究,分析了逆掩斷層封閉機理,在斷裂帶填充物性質與斷層封閉性定量關系模擬實驗和膏泥巖變形特徵模擬實驗基礎上建立了斷層封閉性評價標準及評價方法,以此對庫車坳陷幾個典型構造上逆掩斷層垂向封閉性進行了評價,結果表明現今斷層多是封閉的,這是庫車塌陷天然氣和異常孔隙流體壓力得以保存的主要條件。Jet impingement cooling is an advantage method in heat transfer enhancement owing to its extremely high local heat transfer coefficient and simple structure. as regard as the combustor flame tube cooling structure is concerned, the impingement - converse convection - film composite cooling is an effective method, in this composite cooling structure, the impingement cooling problem could be modeled as impingement inside semi - confined channel
對于沖擊-逆向對流-氣膜復合冷卻的火焰筒結構而言,火焰筒壁面冷氣側的沖擊冷卻實質上是半封閉通道的沖擊冷卻,即沖擊射流從沖擊孔板噴出,沖擊到換熱靶面后形成壁面射流沿通道單方向流出。The generator is verified to be of well performances by experiment. the third part concerns the control system of pm generator in vehicle application by commutating and inversion. considering the development of future power supply of auto electric system and the economizing on energy, the multi - voltage power supply system for future autos power supply system is introduced, and the design is given in detail
最後,結合現代電力電子技術,利用整流橋、逆變器、 mosfet等元器件設計並實現了車用永磁發電機恆壓輸出控制;從未來汽車電氣系統的發展方向和高效節能方面考慮,提出未來汽車的多電壓供電系統的典型配電模型,並對該模型進行具體設計,實現多電壓供電的功能,並給出了控制線路中各主要部分的波形。On the contrary, because of the effect of positive damping provided by the inverter, the unit near a inveter will have no subsynchronous oscillation risk. based on the same method described above, a damping study is carried out for a hybrid ac / dc system, which include a hvdc link and an ac transmission line in parallel
研究表明,系統整流站附近的同步發電機組要承受電氣負阻尼作用,因此有可能引起機組低頻扭轉振蕩模式失穩;而hvdc的逆變站向其臨近同步發電機組提供正阻尼,因而機組不存在次同步振蕩危險。It lurks in the sky and when the time is right, it rushes towards the ground causing significant downdraughts and changes in head wind. microburst first coined by t. fujita, is so dangerous that every pilot would try to avoid it, especially during take - off and landing
