薄膜润滑是20世纪90年代以来广泛研究的新型润滑状态。它是界于弹流润滑和边界润滑之间的一种过渡润滑状态，有着自己独特的润滑规律。文章回顾了薄膜润滑的研究历史，包括薄膜润滑概念的提出、测试技术的发展、薄膜润滑的膜厚特性、润滑机理探索以及计算理论等方面的研究成果与主要进展。

Thin film lubrication (TFL) has been well studied as a new lubrication regime since the 90s of last century. TFL is a transition lubrication regime between elastohydrodynamic lubrication (EHL) and boundary lubrication (BL), which has specific lubrication features. The present paper reviewed the advancement of researches of TFL, which involves the origin of the TFL concept, advancement of measuring technique, TFL's film-forming features, investigation on its mechanism, and computation theories.
