摘要

论文指出，量子系统中的功与能量是量子化的；量子功相当于系统的最高特征能（Debye 能），而固体的超润滑性就是从量子功中推导出来的。超润滑性的前提条件是滑动时接触面的侧向力小于德拜力，这样固体的声子就不会被激发。

Friction as energy dissipation process associated with superlubricity of solids

The paper shows that work in a quantum system is quantized with energy; the quantum work is equivalent to the highest eigenenergy (the Debye energy) of the system and the superlubricity of solids is derived from the quantum work. The prerequisite for the superlubricity is that the lateral force at contact surfaces in sliding is less than the Debye force so that the phonon of the solids is not excited.
