液性平段 的英文怎麼說
中文拼音 [yèxìngpíngduàn]
液性平段
英文
fluid echoless segment-
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。Based on comparison of several technical schemes, the method of sand bedding pre - elevating and step water - filling pre - compressing is adopted. so the dissertation is consist of two parts : ( 1 ) the applicability study for the method of sand bedding pre - elevating and step water - filling pre - compressing, including numerical analyses for the thickness of sand bedding, the consolidation, settlement and stability of foundation, drainage, possibility of foundation liquefaction under seismic loading, et al. ( 2 ) monitoring at construction stage and checking the effect of foundation treatment, including the measurements of the settlement velocity and non - uniform settlement of ring beam under the tank, pore pressures and horizontal displacements in foundation, the pressure distribution at the bottom of oil tank and the strength increase of soils
