压差阻力 [yā chā zǔ lì]
pressure drag
- 溶解性有机物在膜面的附著，对膜过滤压差即膜过滤阻力的变化影响不大，而活性污泥在膜表面的大量沉积将导致膜过滤压差迅速上升。
Soluble organic foulants contributed little but sludge particles deposited on the membrane surface resulted in a rapid increase of the transmembrane pressure. - 结果表明，土壤表面阻力总趋势是随蒸发时间的延长和累积蒸发量的增加而增大，但这种关系有可能被土壤蒸发面和大气间水汽压差的改变所打破，土壤蒸发面和大气间水汽压差是决定土壤表面阻力的主要因素之一。
The results showed that soil surface resistance often increased with evaporation time and cumulative evaporation, but the relation might be changed by variation of difference of vapour pressure between evaporating plane and atmosphere; difference of vapour pressure between evaporating plane and atmosphere was one of the major factors for determining the soil surface resistance. - 摘要同常规的垂直井相对比，采用水平井开采能够大幅度增加油气井与油气藏的接触面积，改变油气藏中井筒附近区域的渗流方式，降低渗流阻力，进而可以利用较低的生产压差来实现更高的油气产量。
As compared with the conventional straight well, the horizontal well can greatly increase the contact area between well and reservoir, change the filtrational mode in the vicinity of wellbore in the reservoir and reduce filtrational resistance, thus obtaining higher oil and gas production by a relatively low producing pressure difference.
