  1. The concentration of feso4 was determined by micro titration with a novelly designed pipette and kmno4 standard solution

    摘要將微型滴定用於硫酸亞鐵含量的測定，設計並使用與微型滴定管精度一致的移液管，比較了微型滴定與常量滴定的測定結果。
  2. With the in - built drip irrigation belt and thin wall chip irrigation belt taken as examples, the flow rate distribution and hydraulic losses of drippers along capillary tubes at different inlet pressures were measured under the conditions of horizontal slope and slope gradients of 0. 5 % and 1 %, then the uniformity of capillary tubes was calculated at different slope gradients and pressures in consideration of the manufacture deviation of drippers

    摘要以內鑲式滴灌帶和薄壁滴灌帶為研究對象，測定了平坡、 0 . 5 %坡度和1 %坡度時，不同入口壓力下滴頭沿毛管的流量分佈和水力損失，並結合滴頭的製造偏差，計算得出不同坡度和壓力條件下滴灌毛管的均勻度。
  3. ( 3 ) based on the experiments data, it has been found that if the emitter discharge of sdi was little, the depth of pipe buried should be shallow, and the distance between two micro holes should be chosen to equal or close the distance between two lateral pipes, if the emitter discharge of sdi was great, the pipe may be buried deeper, and the distance between two micro holes could be greater than the distance between two lateral pipes

    根據一維土柱近似的濕潤輪廓線初步選定了工程設計參數。在地下滴灌灌水器出流量較小情況下，埋深應淺，孔距應選擇和毛管間距相等或接近；出流量大時，埋深可深，孔距大於毛管間距仍可獲得較均勻的土壤水分分佈。
  4. Abstract : problems caused in designing and management including configuring regulating devices, deciding spaces of the last pipelines, and working - out irrigation scheme in reason using drip irrigation in green houses and in covered lands are raising in recent years, theose not only affect benefits but also result in failing of projects

    文摘:近幾年來溫室、大棚種植蔬菜採用滴灌技術的越來越多，但有些工程無論設計上、管理上都存在一些問題，包括調壓設備的合理配置，按土壤、作物、灌水器及滴灌總水量合理確定毛管（或滴灌帶）的間距，以及按大棚蔬菜的耗水特性合理確定灌溉制度等，上述各項確定的不合理，不但直接影響效益，嚴重時可導致工程失敗，值得重視。
  5. 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。
