【Abstract】 Based on adsorbent theory and the law of energy change, the degree of interaction on the surface is determined. The adsorbent layer is defined. Analysis calculation formula on adsorbent thickness is obtained. Adsorbent thickness is the most critical factor for thin film lubrication research, and is a critical point for the analysis of the difference between thin film and thick film. According to theory of interaction of molecule and basic definition of hydromechanics, correcting model of viscosity with exponential function is derived. It can be used to determine the law of change of fluid viscosity in micro clearance. The calculation of bearing properties under the condition of thin film lubrication is made with this correcting model. Experiment data are compared with theoretic calculation. The results show that theoretic calculation is consistent with experiment.
