To achieve good results, try to locate breeding and hiding places of insects ( such as in dark spots, in corners of rooms, in cupboards, cracks in walls, pipes, ducts, behind and beneath sinks and refrigerators, storerooms, cabinets and rubbish bins, baseboards around window frames, door sills and etc. ) before spraying
為令效果更理想,噴灑目標應為發現害蟲或相信有害蟲的地方,如:房間的黑暗墻角、墻壁裂縫、杯櫃和碗櫃、渠管、雪櫃背後、鋅盆底、貯物室、抽屜、垃圾桶、地腳線、窗框和門框周圍等。The aerodynamic design of curve of nozzle adopts perfect gas cresco method to calculate non - existence glutinous model surface, the correct boundary layer of the nozzle wall side adopts sivells - payre method, and the calculation of constringency part of the nozzle adopts stock formula
其中,噴管型面氣動設計採用理想氣體的cresci方法計算無粘型面;噴管的附面層修正採用sivells - payre方法;噴管收縮段的設計採用維托辛斯基公式。And it can help us to open up the utilization scope of frequency changer. the main content have been studied in this paper. for example, the energy saving effect of the frequency changer utilization in tube - well irrigation, spray irrigation and drip irrigation, the influence of the frequency changer to the degree of consistency in tube - well irrigation, spray irrigation and drip irrigation, and the full - scale test of the frequency changer used in tube - well irrigation
本項目在國內首次提出了變頻調速裝置在管灌中使水泵進行「恆量變壓」變頻運行的設想,並首次對變頻調速裝置在農業節水灌溉中的應用進行了實地試驗研究,該研究成果對變頻調速裝置在管灌、微噴及大棚滴灌中的應用具重要的指導意義,對變頻調速裝置的設計研究及其應用范圍的拓展等具有一定的理論意義和很大的實用意義。The flow field of fadw is very complicated, especially in the free vortex jet zone. so the method is according to the ideal flow, including the design of the asymmetric supersonic laval nozzle and the diffuser
所以,本文所建立的fadw的基本設計方法是理想狀態下的設計方法,其中主要包括非對稱超音速噴管的設計和氣動窗口擴壓器的設計方法。分享友人
