The initial water content can evidently influence the amplitude of this change of its hydraulic gradient.
受水势梯度的影响，犁沟内非饱和水可以侧向补给相邻畦埂的土壤。
Affected by hydraulic potential gradient, the unsaturated soil water in the furrow soil may supply laterally the ridge soil of adjacent furrow.
水势反映土壤水的能态，而水势梯度则是决定水流方向和速度的重要因素。
Water potential reflects energy level of soil water and the gradient of water potential is an impotent factor describing direction and velocity of water flow.
宏观根系吸水模型的边界条件容易确定和控制，但该类模型忽略了根系微域的水势梯度和其他类似现象。
The boundary conditions were easily determined and controlled by the macroscopic models, while the gradient of water stress in the micro-zones of roots was ignored.
