big trough
解釋
大地槽-
Fluid noise mainly comes from out put pulsation of rate of flow, the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition. the v trough on the port plate can reduce the fluid noise. in this paper, the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12. 3 and its length was 5mm and the cross section was an equilateral triangle
流體噪聲主要來源於輸出流量脈動，造成輸出流量脈動的主要原因是閉死容積在大圓弧段壓力切換時產生的瞬時高壓迴流，在配流盤上開設v型尖槽可降低因高壓迴流而引起的流體噪聲，本文以截流作用和液體的可壓縮性為理論依據，以matlab語言為工具，對原配流盤上的v型尖槽進行了理論計算，繪制出p - t圖線，分析了它的不足，並對原有v型尖槽進行了優化設計，得出了v型尖槽的最佳幾何尺寸：配流盤平面上的v型尖槽的兩邊的夾角為12 . 3 ，槽長5mm ，槽的橫截面為等邊三角形。 -
Often, as i still lay at the bottom, and kept no more than an eye above the gunwale, i would see a big blue summit heaving close above me ; yet the coracle would but bounce a little, dance as if on springs, and subside on the other side into the trough as lightly as a bird
我躺在船底，睜開一隻眼睛從船邊向上望去，常常看到一個藍色巨浪聳立在我的頭頂，小艇縱身一躍滑向浪渦處，像裝上了彈簧一般。 -
V pattern ( 53. 9 % ), its isis varied continuously from big to small, then from small to big and form a gently inflexion in the trough. reversal n pattern ( 25
9 ，在這種型式的振蕩中， isi逐漸由大到小又由小到大依次連續變化，且isi在波谷處形成一個較平緩的拐點；倒n形佔25 -
Concentrations of total suspended matter ( ctsm ) is unanimous with observational data and other scholars " researching results. the distribution of ctsm is higher along coast than other areas there is a tongue - like zone with high ctsm from north to southeast. the transport simulation result reveals that sm can spread to the okinawa trough for enough sea water mixing in winter. but in summer. sm can not traverse the big water barrier of kushino for different circulation character. this difference is probably related to the shifting n - s monsoon
懸浮體輸送表明，在冬季，懸浮體除了在陸架上發生擴散外，由於海水的強烈混合作用和環流的季節性變化，部分中、底層懸浮體可擴散至沖繩海槽甚至西太平洋;在夏季，由於海水層化及夏季環流特徵，懸浮體基本不能穿越黑潮這一水障，這一差異可能是由於季風和不同環流特徵所引起的。 -
The hukou waterfall on the huanghe river west of jixian county, shanxi, is formed when the river flows to the hukou mountains on the shanxi - shaanxi border and its 250 - meter - wide bed, sandwiched between the canyons on its banks, abruptly narrows into a trough 50 meters wide and 30 meters deep and falls down into a big stone - strewn pool
當流至壺口時，寬約400多米的河床，突然收縮到四五十米，形成特大型馬蹄狀瀑布，河水似從一巨型壺口瀉下。主瀑布寬40米，落差近50米。 -
