摘　　要：液-固二相流体润滑是近年来发展起来的一种新型的润滑理论,它可以为实际工程提供更为准确的指导。文章介绍了液-固二相流体润滑的学科基础,回顾了液-固二相流体润滑的研究进展,并重点介绍了粘度模型、入口颗粒运动形态分析模型、连续理论模型、颗粒产生的摩擦力(PIF)模型,讨论了液-固二相流体润滑进一步发展所存在的问题。The liquid-solid lubrication is a new research area of lubrication developed in recent years, and the theory of liquid-solid lubrication can provide a more precise instruction for the industry. The academic fundamentals of liquid-solid lubrication are intrdoduced, the developments of liquid-solid lu- brication researches are reviewed. A detailed discussion is made on the viscosity model, the model of particle behavior in the inlet zone, the model based on the continuum theory, and the particle induced friction （PIF） model. The issues for future study of liquid-solid lubrication are pointed out.
