恒定

Results indicated that the steady-state model of constant-head well permeameter could be used to design the emitter discharge rate for different water-conducting device specifications and soil types.

研究结果表明，用于描述恒定水头钻孔积水入渗法求解土壤饱和导水率的稳态模型能够较好地设计与不同类型土壤和导水装置尺寸相匹配的适宜滴头流量。

The steady-state principle of constant-head well permeameter, which was used to calculate the field-saturated hydraulic conductivity, was applied to quantify the suitable emitter discharge rate for indirect subsurface drip irrigation under different water-conducting device specification conditions in this text. Using the calculated emitter discharge rate to supply water, characteristic parameters of wetted soil volume were studied during the water movement process.
