This is what we call superconductivity, no resistance flow.
这就是我们所称的超导性，无阻力流动。
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。
At low temperatures, electrons in the superconductors flow collectively, unfettered by resistance.
在低温情况下，超导体中电子将会共同流动，不受电阻约束。
