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。
This presents a tortuous flow path to ensure intimate contact of the impurities on the surfaces and within the pores of the carbon.
该过滤器可提供一条曲折的流路，确保对表面或以及在碳毛孔内部的杂质彻底清除。
Also as dendrites solidify and shrink in volume replacement of melt must flow along a tortuous path of interleaving dendrites.
