In the intergranular spaces of rocks, however, fluid must flow around and between grains in a tortuous path; this winding path causes a resistance to flow.
然而，在粒间孔发育的岩石中，流体必须在颗粒周围的曲折通道中流动；而这种曲折通道会对其流动产生阻力。

All will have on the blood flowresistance, while the study found that blood circulation in the main resistance comes from a small artery, arteriole.
所有的血管对血液流动都会产生阻力，而研究发现，血液循环中阻力最主要来源于小动脉、微动脉。

The flowresistance of foam is affected by those parameters such as surfactant concentration, oil saturation, temperature, permeability, water and gas phase velocity, etc.
