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

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。
When we designed the system, we considered some key factors such as the system must deal with and store a great deal video and audio data, the capability of the hard disk in the server and client, hi the part of video compression, we choose the currently mpeg - 4 video constringent card to complete the collecting and compression of the video and audio signals

The channel capacity achieved in our experiments was better than that of the dual homodyne coherent state, homodyne coherent state and squeezed state communication when the average photon number exceed 0. 99, 1. 11 and 2. 06 respectively. it is more interesting that we found in the experiment, that the maximum channel capacity for a single mode - fock state communication can be surpassed with our system when the average photon number exceed 11. 302
