Affected by hydraulicpotential gradient, the unsaturated soil water in the furrow soil may supply laterally the ridge soil of adjacent furrow.
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。

Petroleum accumulations should be within the vertically relative lower hydraulicpotential combined with laterally relative lower potential in overpressure areas.
油气聚集带是在纵向上相对低势层段和平面上相对低势区的结合部位。

However, the oil based hydraulic systems present some serious problems, such as potential for fire.
