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

This method rounding the keen vertexes on the plane antennas fits for not only wide slot antennas and bowtie antennas but many other plane ones. the method is not applied first in the thesis ; however, the foregoing papers did not do some summarizations on it
這種在天線尖銳頂點處倒圓角來改善天線性能的方法不僅僅適用於寬槽天線和蝴蝶結天線，對很多平面天線也是適用的，此論文並非第一個應用本方法的工作，但是前人並沒有對此進行總結，本文總結的這一改善天線性能的方法得到多篇已發表的文獻支持。
