According to the characteristics of fluid-solid adsorption and the change of intermolecular energy, the relationship between surface flow and solid interaction is determined, and the surface adsorption properties and adsorption layer are described. The expression of adsorption layer thickness expressed by energy is obtained. The important parameters in the expression of variation calculation - the thickness of adsorption layer and the description of viscosity are the basis of the research in the field of lubrication engineering. The research of this paper is suitable for the research of working on the basis of fluid film and is one of the problems that must be solved in the research of nanometer lubrication theory.
