- ( 4 ) through the hydraulic property experiment of micro - hole lateral pipes of simple sdi in air , it was found that the average pressure of 60 mitre length lateral pipes was at the position of per 40o / o ~ ~ ~ 50 % of the effectual pipe length from the fist micro - hole , major pressure - loss was occurred at the ahead part of half pipe . the pressure uniformity reduced with orifice aperture ? increasing , and the relationship between pressure uniformity and initial water pressure was poor . running under the initial water pressure of 1 . 5 meter , the discharge uniformity reduced with orifice aperture ? increasing , and when the orifice aperture smaller than or equal 1 . 0mm , irrigation uniformity could achieve above 0 . 6
（ 3 ）通過對空氣介質(zhì)中簡易地下滴灌的微孔毛管試驗研究發(fā)現(xiàn)： 60m管長的毛管平均壓力水頭的位置基本上在距第一孔口的有效管長40 - 45的地方；大部分水頭損失發(fā)生在毛管的前半部分；壓力均勻度隨孔徑的增大而減小，但與初始工作水頭關(guān)系不密切；在1 . 5m以下的工作壓力下運行，沿程出流均勻度隨孔徑的增大而降低，當(dāng)孔徑不大于1 . 0mm時，灌水均勻度可以達(dá)到60以上；當(dāng)孔徑大于等于1 . 2mm時，灌水均勻度低于50 。
