  2. ( 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。
  3. A soil having a uniformity coefficient smaller than 2 is considered uniform.

    均勻系數小於2的土壤可視為均質土。
  4. After the observation and analysis on the uniformity coefficient of irrigation and the distribution of soil moisture under each different treatment, a result was got that 35cnrs embedded depth is comparatively appropriate for vegetable cultivation for the high uniformity coefficient and the vegetable cultivation for the high uniformity coefficient and the concentrated distribution of irrigation water in the main root zone

    通過對各處理灌水均勻度和土壤水分分佈的觀測、分析，認為滲灌管埋深35cm時對蔬菜栽培是比較合適的。此時灌水均勻度高，灌溉水大部分分佈在蔬菜主要根系區。
  5. On the other hand, the hydraulic performance of the hole, including flow rate coefficient and uniformity of flow rate, have been tested as standards to evaluate the quality of holes punched by laser drilling machine with much better results than that punched by mechanical drilling machine. the shape of holes taken by a microscope photograph can also give detail and well explanations for this test results

    對噴孔水力學性能的試驗研究表明，本文提出的用噴孔水力學性能指標（流量系數和流量變異系數）來評價微噴帶激光打孔機質量的方法是可行的，並證明微噴帶激光打孔機的質量明顯優于機械打孔的質量，用顯微鏡觀察噴孔的形狀的照片也同樣證明了這一點。
  6. Coefficient of uniformity, uniformity coefficient

    不均勻系數
