water-table gradient

Further studies founding that the root surface area under MS treament was big, the water flow was reduced under unit time, unit pressure gradient and unit surface area of root.

研究发现，甜高粱在MS处理下具有较高的根系表面积，使其在单位时间内，单位压力梯度下流经单位根表面积（或长度）的水流降低。

The effects of the geothermal gradient and bottom water temperature are great.

由此可见，在这几种因素中，地温梯度和底水温度对稳定带厚度的影响较大。

Alterations of renal tissue water content and effects of Anisodine, Anisodamine and Buscopan on these changes were investigated with gravity gradient method in oleic acid induced acute renal failure.

采用比重梯度法定量研究了油酸致急性肾衰大鼠肾组织水含量的改变及樟柳碱、东莨菪碱、山莨菪碱对这些改变的影响。

And this paper build the relationship formula between threshold pressure gradient and air permeability, water saturation.

并且建立了油水两相启动压力梯度与空气渗透率、含水饱和度的关系式。

Terrestrial stress is a main control on hydrostatic head of reservoir, and its gradient powers oil, gas and water migration.

地应力是影响储层沉积水水头的主要因素，地应力梯度是油气水运移的主要驱动力。
