本文研究了在60 - 70khz频率上振荡的钢板与钢试样之间的摩擦力与振荡幅度的关系。当振荡幅值从0增大到0.1 μm时，静摩擦力迅速衰减。然后，随着振幅的进一步增大，直至0.5 μm左右，力略有减小。实验数据是在一个理论模型的框架内解释的，该模型包括两个在随机电位中运动的物体，并由一个随机振荡的键耦合。对该模型的分析表明，摩擦力表现出质变的振荡幅度对应于对摩擦力产生最大贡献的空间尺度。由此得出结论：钢-钢偶的摩擦起源于约50 nm的尺度。
The force of friction between a steel plate and a steel sample oscillating at a frequency of 60–70 kHz has been studied as a function of the oscillation amplitude. The static friction force rapidly decays when the oscillation amplitude increases from zero to 0.1 μm. Then, the force decreases only slightly as the amplitude grows further up to about 0.5 μm. The experimental data are interpreted within the framework of a theoretical model comprising two bodies moving in a random potential and coupled by a randomly oscillating bond. An analysis of this model shows that the oscillation amplitude at which the behavior of the friction force exhibits a qualitative change corresponds to a spatial scale producing a maximum contribution to the frictional force. From this, it is concluded that friction in the steel-steel couple originates on a scale of about 50 nm.
