    本文利用復合形優化演算法建立了起落架緩沖系統參數識別與系統優化模型，對緩沖器空氣壓縮多變指數和油孔流量系數等不可測參數的識別和著陸、滑跑載荷多目標優化問題進行了討論。
  3. ( 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 。
