海平面壓力 的英文怎麼說
中文拼音 [hǎipíngmiànyālì]
海平面壓力
英文
aea-level pressure-
For the overpressure, here p is the overpressure at altitude and is that at sea-level.
關于超壓力，此處P是指在高處的超壓力；是海平面上的超壓力。The main work and conclusion for this paper is as following : according to the flashover test results of several kinds of iced insulators under positive voltage and negative voltage, this paper obtained : for the single porcelain insulator, the single glass insulator and the composite insulator bridged completely by icicle, the metal cathode ' s strong ability of emission electron is the primary reason that results in the lower negative flashover voltage ; the position difference of the high resistance district in method anode side results in that porcelain insulator cluster and glass insulator cluster have an evident effect of polarity ; when less ice and no icicle at the brim of the sheds, due to numerous non - polar arcs on the composite surface, the effects of polarity of composite insulator was lost using the test method of the average flashover voltage in the freezing period, dc flashover performances were investigated of several insulators with some typical structures and different material
本文的主要工作和結論如下：在人工氣候室內，根據不同覆冰絕緣子正、負極性下的閃絡試驗結果，得出負極性電弧金屬陰極的強電子發射能力造成了單片瓷、玻璃絕緣子及被冰凌橋接的合成絕緣子有較低負極性冰閃電壓；正極性電弧金屬陽極側產生高電阻區所處位置的差異使得瓷和玻璃絕緣子串具有明顯的極性效應；覆冰較少時，合成絕緣子表面出現數量較多的非極性電弧使合成絕緣子無極性效應。利用覆冰期內平均閃絡電壓的試驗方法，對不同材質和結構的絕緣子在覆冰、低氣壓和污穢共存環境中的直流閃絡特性進行了研究。試驗結果表明，直流平均閃絡電壓隨著海拔的升高、覆冰量的增加以及污穢度的增加而降低，且其特徵指數與絕緣子結構、覆冰量、覆冰狀態、污穢度等有關。On current projections, substantial parts of the world risk being left uninhabitable by rising sea levels, reduced freshwater availability or declining agricultural capacity. this will exacerbate existing migratory pressures from rural areas to cities, from unproductive land to more fertile land, and across international borders
從目前的狀況來看，海平面的上升、淡水資源的減少以及農業生產能力的下降，將使世界上絕大多數地區淪為不適宜人類居住的不毛之地，這將進一步加劇從鄉村到城鎮、從土地貧瘠地區到豐腴地區乃至跨國界的移民潮所帶來的壓力。In this text we make a diagnosis of linear and nonlinear response of quasi - quadrennial ( qq ) and quasi - biennial ( qb ) component of nino3. 4 index by using reanalyzed ncep / ncar data of sst, wind stress ( pseudo stress ) field, ssp, then have a time and spatial analysis of wind stress field by using mssa, and finally find the importance and contrast the effect of different wind stress field forcing the sea so as to find the cause ofenso irregularity
本文首先分析海表溫度（ sst ） 、風應力場、海表面氣壓（ slp ）等ncep ncar再分析的月距平場對于nino3 . 4指數的準4a （ qq ）和準2a （ qb ）振蕩成分的線性和非線性響應，接著用mssa （多通道奇異譜分析）對風應力場進行時空特徵分析，最後用一個熱帶太平洋動力海洋模式研究具有不同振蕩性質的風應力場對海洋強迫作用的重要性及差異，尋找enso不規則性的原因。Through analyzing bed ' s response to wave, in the condition that super - stratum is more hard and second - stratum is more soft in region of interest, super static interstitial hydraulic pressure amplitude die away rapidly between stratums, before in sight of boundary between hard and soft stratum, plane effective pressure increase to max. shear stress reach peak value when bed thickness is approximately 2. 7 meters, then it will decrease to the minimum on the place where the flexible soil has a common boundary with the rigidity, so the boundary is the most destroy plane on engineering. on the basis of reconnaissance in situ, in normal situation of sea, the structure slides to the basin along the boundary
通過對底床在波浪下的響應分析，對于研究區底床上層較硬而第二層較軟的情況，超靜孔隙水壓力幅值在層間交界處迅速衰減，在臨近硬、軟地層交界處前，水平有效應力增至最大，剪切應力在底床厚度大約2 . 7米左右達到峰值，然後減小，到硬、軟層土交界位置，達到最小，因此這個界面就是最容易發生破壞的工程軟弱面，現場勘查證明，即使在正常海況下，構築物也會沿坡以此交界面為滑動面，緩慢向「盆」底滑動。East china is located in the economically developed, intensely populated southeast coastline of china, where on the average the market maturity, economic development and consumption level are more advanced than those of other places of china. although east china railway passenger transportation industry is faced with plentiful consumption demand, it gradually assumes more and more pressure in an improving market - oriented economic environment based on the following analyses : ( 1 ) the rapid development of aviation and highway transportation lead to the unprecedented fierce competition resulting in a great challenge to the railway passenger transportation to expand its market share
華東是我國東南沿海經濟發達、人口稠密地區，市場化進程、經濟發達程度和消費水平均領先於全國。華東鐵路旅客運輸業面對的是一個客流量充沛的旅客運輸市場，但是，在日益完善的市場經濟環境中，它面臨的壓力也越來越大，這是基於兩方面的原因：一方面由於航空和公路客運的超常發展，市場競爭空前激烈，對鐵路客運擴大市場份額形成很大的挑戰；另一方面作為一個處在轉型過程中的國有特大型企業，對市場的研究、對旅客消費心理的研究還剛剛起步，市場營銷尚處在初級階段。According to the test results of localization and shear bands formation under the consolidated undrained plane strain compression tests on soft clay in shanghai, it was found that the deviator stress of shear band beginning to form was very close to its yield point in clay soils
摘要根據上海軟土在固結不排水平面應變壓縮試驗條件下應變局部化和剪切帶形成的實測研究結果，發現粘性土剪切帶開始形成的偏應力為其屈服點。分享友人
