( 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 ）通過對空氣介質中簡易地下滴灌的微孔毛管試驗研究發現： 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，當孔徑不大於1 . 0mm時，灌水均勻度可以達到60以上；當孔徑大於等於1 . 2mm時，灌水均勻度低於50 。Polyolefin pipes for the conveyance of fluids - determination of resistance to crack propagation - test method for slow crack growth on notched pipes notch test
