varying-head

基本解释

Water infiltration of water storage pit irrigation is under varying-head conditions.
蓄水坑灌條件下的土壤入滲是在變水頭作用下進行的。
The research results will have an important value for to study further varying-head infiltration and soil moisture characteristic of water storage pit irrigation .
這一研究成果爲進一步研究蓄水坑灌條件下的變水頭入滲及土壤水分運動特性奠定基礎。
In the meantime the time variation of the water level in the ditch has been taken into account, therefore the groundwater head are time-varying as the groundwater flows toward the drain system.
在討論這個問題時，又考慮進了排水溝中的水位也是隨時間而變化的，因此在地下水流動過程中的任一瞬時，其地下水頭差也是一個變量。
