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。The forming and changing of lan - yang plain was affected by the tectonic sinking, fluctuation of sea level, and alluvial process
摘要蘭陽平原的形成與變遷主要受到地盤沉陷、海水面變動與河川沖積等因素所影響。By changing the tube into d shape ( semicircle ), the pallet can fully contact with the tubes ( re. picture 2 ), the cooling speed can be shortened by the contact surface increased
如果把管子的形狀改成d形（半圓形） ，托盤在管子上的接觸為平面接觸（如圖2所示） ，接觸面積比圓管大大增加，熱量以最快的速度從托盤傳至排管並由管內的冷劑蒸汽帶走。When choosing evaluative indexes, we take four aspects of fatalness of sea level rise hazards, vulnerability of land system, socio - economic and ecological vulnerability, and defending ability. we draw the map based on the relief map and the land utilizing map of 1 : 100000 scale, gain altitude values ( range of 1 km 1 km ) and the fundamental data of evaluation in the studied area using the software of mapinfo and socio - economic statistic data
運用mapinfo軟體和社會經濟統計數據，以盤錦市1 ： 100000地形圖和土地利用圖作為底圖，獲得地面1km 1km范圍高程值以及評估單元基礎數據，並計算出在沒有防護、不同潮位背景、海平面上升不同高度的條件下，遼河三角洲未來海平面上升將淹沒的土地面積、受災人口和經濟損失，以及不同土地利用類型的淹沒面積及相應的經濟價值。Promote condition to prevent parching, prolong continuous working time more than one time. larger applicant scope, both thin and glutinous materials can be adapted. only o - type ring should be replaced when maintaining without heavy tools and dead angles. wash thoroughly, high efficient, far more than coil heat exchanger. heat transmit coefficient is close to plate system, producing cost is high and the floor space is large
改善了結垢的狀況，連續生產時間延長一倍以上，適用范圍更加寬廣，稀薄狀、粘稠狀物料均能勝任，維護時只要更換o形圈，無需笨重的工具，無死角，清洗徹底，效率高，換熱效率遠大於盤管式，傳熱系數接近板式，製造成本較高，佔地面積較大。分享友人
