( 5 ) it was more precise for using darcy - weisbach formula to calculate the hydraulic pressure slope curve in the lateral line, but too complexity. although i - pm wu formula is simple, the estimated results were not agreement with the measured data. a coefficient including irrigation uniformity was presented to modify i - pal wu formula, and the results were agreement after using the coefficient

    ( 4 )利用達西?韋斯巴赫公式計算微孔毛管的沿程水頭損失具有較高的精度,但計算復雜,吳義伯公式計算雖較簡單,但在灌水均勻度較差時誤差較大,為此對吳義伯公式進行了修正,提出了修正系數的計算經驗公式,取得了良好的結果,為簡易地下滴灌工程設計中水力計算建立了簡化公式。
