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。Ask students to demonstrate a proof of the theorem stating that the sum of the interior angles of a triangle is equal to 180 ?

研究表明：裂面狀態對k _的大小沒有影響，而對k _的影響卻很大，相同應力條件下，裂面狀態會影響裂紋的開裂角和開裂方式；有限板的邊界對應力強度因子有一定的影響，其k比無限板中的k略大；裂紋間的距離、夾角等因素對裂紋間的干涉效應均有較大影響，裂紋間的干涉效應對應力強度因子的影響非常顯著，只有當裂紋間的距離充分大時，干涉效應才可忽略。This works has complete product specifications and varieties. it can offer double - faced coating adhesive, single - faced coating adhesive, fully automatic linear edge sealing machine, double - faced coating adhesive automatic straight - line, hand - operated curve & straight - line, three - row, four - row, six - row, high precision multi - drill, precision multi - drill, precision pulling bench saw, 45 - 135 aluminum frame and wooden mirror frame angle cutter, stroke charge open sawing machine, hard alloy saw sharpening machine, hydraulic press etc. it supplies woodworking machinery parts, fittings, clamp and so forth. it also receives the transport business for vart customers
