Calculating Model of Adsorbent Layer Thickness and It''''s Application

Based on adsorbent properties and change law of energy between molecules,the interaction between fluid and solid surface could be determined. The adsorbent characteristics of the surface and adsorbent layer could be defined then. The calculating formula of adsorbent layer thickness expressed as energy could be obtained. Therefore, the adsorbent layer thickness, an important parameter, which describe viscosity change on the surface will be determined. Viscosity parameter is the theoretic base for the research of lubricant technology. This research mostly applies to the study of fluid film, which is one of the problems that must be resolved on lubrication theory research in nanometer.;
