摘要
根据流、固体表面吸附特性和分子间能量的变化规律来确定流、固体表面相互作用的程度 ,以定义表面吸附性能和吸附层 ,并得出以能量表示的吸附层厚度计算公式 ;吸附层厚度对流固特性、管流问题及薄膜润滑问题等的研究具有重要意义。特别适用于以流体膜为基础进行工作的研究 ,是纳米级润滑理论研究必须解决的问题之一。
Based on adsorbent properties and change law of energy between molecular, the interaction degree between fluid and solid surface was determined. The adsorbent characteristics of the surface and adsorbent layer was defined. The calculating formula of adsorbent layer thickness based on energy was obtained. The adsorbent layer thickness is very important for fluid-solid and fluid-fluid characteristics, pipe-flowing problems and thin film lubrication research. This research can be used to study fluid film, and will be one of the problems that must be resolved on lubrication theory research at the nanometer.
