陡比降 的英文怎麼說
中文拼音 [dǒubǐjiàng]
陡比降
英文
high gradient-
The study area is composed of sandstone & conglomerate reservoir of alluvial fan & fan delta, which belong to sha3 lower member and sha4 upper member of lower tertiary of yong " an town oilfield in dongying depression. the target stataum develops in the hanging wall of the synsedimentary fault in the scarp zone of dongying depression. the frequently intense movements result in the variation of sandstone and conglomerate reservoir and the evolution of the time and space of sha3 lower member and sha4 upper member in yong " an town oilfield
研究區是東營凹陷永安鎮油田沙三下段、沙四上段的沖積扇和扇三角洲砂礫巖體，目的層發育在東營凹陷陡坡帶同生斷層的下降盤，因斷層多期強烈活動，導致永安鎮油田沙三下段、沙四上段的砂礫巖體成因類型多，時空演化變化大，在扇根一帶小層對比難度大，給油田開發帶來很大的難題，在這種背景下進行流動單元研究難度更大。Besides, the sedimentary facies of upper ganchaigou and lower ganchaigou formation were also mapped in supersequences which are the main target strata for exploration. the high resolution sequence stratigraphic framework showed the genetic relationship between the distributions of sedimentary facies and their tectonic settings. the near - source sedimentary systems such as subaqueous alluvial fan and lake - floor fan are often deposed in rise - hemicycles in the steep slope background in the north, the coarse lithology of fan - delta prograded from north to south in fall - hemicycles, and the braided stream facies are formed in the rise - hemicycles in gentle slope background in the south, braided stream facies prograded from sorth to north in the fall - hemicycles, but the lacustrine facies and salt lake facies developed in the middle part of the area
詳細的沉積相研究發現，紅獅地區第三系發育有沖積扇、水下沖積扇、河流、三角洲、扇三角洲、湖泊和湖底扇7種主要沉積相類型，並對作為區內主要勘探目的層系的下乾柴溝組和上乾柴溝組進行了以超層序為單位的沉積相平面編圖，以較高的時間解析度揭示了區內沉積相帶的平面展布及其在不同構造背景中的分佈規律，比如在北部的凹陷陡坡背景下，上升半旋迴低水位期通常發育有水下扇、湖底扇等陡岸近源特徵的沉積體系，下降半旋迴高水位期，扇三角洲相粗碎屑巖由北向南進積;在南部的凹陷緩坡背景下，上升半旋迴主要發育辮狀河流相，下降半旋迴辮狀河三角洲相由南向北進積;而中部紅柳泉一獅子溝一帶則為湖泊相沉積和鹽類沉積。He alternately employs such contrasts as between light and shade between largeness and diminution between openness and seclusion and between elevation and depression
園林的主人巧妙的運用對比的手法來製造與眾不同的視覺效果：例如明亮與灰暗，放大與縮小，開闊與隱居，陡升與驟降等等。With synthesize slope ratio increasing, the stability of cutting slopes decreases, but the stability of sharpen slope affected by natural slopes ratio changes rarely, the stability of cutting slope that height is 30m is change notably due to slope type, whose single slope ratio with madao is inferior to the slope that upper ratio is less than lower ratio with platform in middle part. but the stability of cutting slope with 50m height is little change with the slope type change. with same stratum, slope height, slope type, the cutting slope is inferior to the sharpen slope in stability
結果表明，地層含水量在12 . 0 18 . 0變化范圍內，各種挖方邊坡穩定性均隨濕度的增大而顯著降低；路塹邊坡的穩定性隨綜合坡比的增大而降低，但削坡受自然坡比影響，隨綜合坡比的增大其穩定性基本不變；坡高30m的路塹邊坡穩定性因坡型改變而有明顯變化，且單一坡比多級馬道型邊坡的穩定性較上緩下陡平臺型邊坡的穩定性差，但坡高50m的路塹邊坡穩定性因坡型變化而基本不變；當坡高、坡型、地層條件相同時，路塹邊坡的穩定性較削坡的穩定性差。The descending part of the curves are much sharper than the ones under the normal temperature. the ductility of the concrete will also get worse and the brittleness will increase
應力?應變曲線形狀隨負溫值的增大變得高而窄，曲線的下降段比常溫陡直，混凝土的延性變差，脆性增大。分享友人
