摘要：

Flow of 2D Aux lines confined to narrow channels has been studied. In the solid, (in)commensurability between lattice and channel width cause mobility oscillations from which the actual channel width follows. In the liquid, the oscillations disappear and flow is dictated by the shear viscosity eta. By repeated experiments for different channel widths, eta is determined for the first time. It diverges according to eta proportional to xi(+)(2) (T, B). An indication for the hexatic-to-liquid transition is also observed.
