我们用石英晶体微天平技术测量了氪膜在金表面的滑动摩擦。通过缓慢地增加基板振荡的振幅，我们观察到从锁定到基板的膜到滑动膜的急剧转变。这种转变的特点是滞后的耗散和惯性质量的振幅减小。最后，这种转变对薄膜覆盖率的依赖关系进行了详细的研究。
We have employed the quartz-crystal microbalance technique to measure the sliding friction of krypton films physisorbed on gold. By slowly increasing the amplitude of the substrate oscillations, we have observed a sharp transition from a film locked to the substrate to a sliding one. This transition is characterized by hysteresis both in dissipation and inertial mass as the amplitude is decreased. Finally, the dependence of this transition on film coverage has been studied in some detail.
