畦灌水流推进过程计算模型对确定灌水技术要素、田间平均入渗率和糙率有十分重要的作用。
Border irrigation current advancement process model plays an important role to determine irrigation technical index, average field infiltration rate and roughness coefficient.
基于田间实测的地表水流推进过程，利用水量平衡法推求波涌灌溉间歇供水条件下的土壤入渗参数。
Based on water flow advance data observed in fields, infiltration parameters under surge water application were determined with water balance method.
研究表明同一次畦灌过程中地表储水形状系数并非恒定值，而是随灌水时间和水流推进距离等因素变化的。
Research results showed that the surface shape factor was not a constant value, but a variable value with the change of irrigation time, water advance distance and other factors.
机器的 推进器包含了大直径慢速转动的 螺旋桨，而且推进水流由喷嘴送出，以避面剧烈搅动扰乱了结块的淤泥。
The thruster contained a large-diameter, slowly rotating blade with nozzles that diffused the propulsive flow, minimizing the churning that would otherwise disturb the caked silt.
