  • irrigation : n. 1. 灌溉;水利。2. 【醫學】沖洗(法),〈pl. 〉沖注洗劑。adj. -al ,-ist n. 灌溉者,水利專家。
  • by : adv 1 在側,在旁,在附近。2 (擱)在一邊,(放)到旁邊,(存)在一旁;收著。3 (由旁邊)經過,過...
  • infiltration : n. 1. 滲入;【醫學】浸潤。2. 【軍事】滲透,通過;滲透活動。3. 【化學】滲濾。
  1. And then, the irrigation performance including irrigation efficiency, application efficiency and distribution uniformity were evaluated by using infiltration parameters and soil parameters. the results indicate surge furrow irrigation is suitable to hilly mountain areas

    利用入滲參數以及田間基本參數,對灌水質量:儲水效率e _ n 、灌水效率e _ a和灌水均勻度e _ d進行了評價,評價結果表明在丘陵山區適宜進行波涌灌溉。
  2. However, the movement and transformation of n in soil under fertigation remains unclear. the methods of simulation experiment and culture experiment were used to study the movement and transformation of n in soil under fertigation by drip irrigation. the main experimental results were shown as folio wings : ( 1 ) the water infiltration under drop irrigation is a point infiltration ; and the soil moisture in vertical and horizontal directions was increased with the irrigation time, and the movement rate were decreased with the irrigation time

    本研究採用室內模擬試驗和生物培養試驗相結合的方法,研究了在滴灌施肥條件下,化學氮肥施入土壤后的遷移、轉化規律以及對作物生長的效應,獲得了以下主要結論: ( 1 )滴灌條件下水分以點源入滲土壤,水平和垂向的濕潤鋒均隨入滲時間的增加而逐漸變大,在入滲開始階段濕潤鋒的推進速率較大,隨入滲時間的延長,濕潤鋒的推進速率逐漸變慢。
  3. ( 2 ) the emitter discharge of simple subsurface drip irrigation is greater than the infiltration rate after formed saturate loop in the short time. infiltration rate under subsurface drip irrigation is not only affected by soil texture, original soil moisture content and soil bulk density et al, but also by emitter discharge, which affect by water pressure

    ( 2 )地下滴灌的灌水器出流量一般在較短時間內形成飽和圈后,土壤入滲速率不僅受到土壤質地、土壤初始含水率、土壤容重等因素的制約,而且還與影響灌水器出流速率的壓力水頭有關。
  4. Based on the fundamental theory of dynamics of soil moisture and the condition of water storage pit irrigation, numerical modeling of soil moisture movement of single water storage pit in heterogeneous soil is established. adi ( alternating direction implicit method ) and gauess - seidel iterative method are used to solve it. by using the simulated value of modeling, the relation of water injection volume and maximum horizental distance of moisture frontal are concluded. according to the relation, interval of pits are derived. then, after analyzing the infiltration characteristic of soil moisture under the condition of interference infiltration in multi storage pit, numerical modeling of soil moisture movement of multi water storage pit in heterogeneous soil is established, and its numerical solution is also acquired

    利用adi (交替方向隱式差分法)結合gauess ? seidel迭代法對模型進行數值求解。利用模型的計算結果得出了單坑注水量與濕潤鋒最大水平推進距離之間的關系,並據此確定了坑距。在此基礎上,通過對多坑干擾入滲條件下土壤水分入滲特性進行分析,太原理工大學碩士研究生學位論文建立了蓄水多坑非均質土壤水分運動數學模型,並對其進行數值求解。
