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。

On one's life's journey there's path one has to take-the tortuous path of Youth.

在每个人的人生旅途中都有一条必然要走的弯路，那就是青春的弯路。

Also as dendrites solidify and shrink in volume replacement of melt must flow along a tortuous path of interleaving dendrites.

此外，作为晶体固化和量的收缩，熔化物的替代品一定会沿着交错的晶体网络流过一段曲折的路程。
