我们实验研究了变粗糙度衬底上薄液体吸附薄膜中的横向流动。我们发现，由于纳米尺度的粗糙度，薄膜平衡横向起伏的能力明显弱于薄膜厚度。我们的结果表明，这是真实表面上吸附薄膜的一个非常普遍的特征。这对于吸附层中的传输起作用的所有系统来说都是非常重要的。
We investigate experimentally the lateral flow in thin liquid adsorbate films on substrates with variable roughness. We find that, as a consequence of nanoscale roughness, the ability of the films to equilibrate lateral fluctuations depends remarkably weakly on film thickness. Our results suggest that it is a quite general feature of adsorbate films on real surfaces. This is of substantial importance for all systems in which transport in adsorbed layers plays a role.
