从吸附分子间侧向相互作用出发，基于Ｔｅｍｋｉｎ吸附等温式，运用统计热力学方法，提出了摩尔吸附分子间相互作用能的概念及求解方法，分析了吸附分子相互作用对油膜极化电阻（或油膜防护性能）的影响，并通过实验和理论计算考察了常用润滑添加剂的最大油膜极化电阻和摩尔吸附分子间相互作用能．研究表明：添加剂摩尔吸附分子间相互作用能越小，则含该添加剂油膜的油膜极化电阻越大，油膜对金属腐蚀的防护性能越好．图２，表１，参８．
Based on the Temkin adsorption isotherm and the statistical thermodynamics method, the concept and solution method of the intermolecular interaction energy between Molar adsorption molecules are put forward based on the Temkin adsorption isotherm. The influences of adsorption molecule interaction on the polarization resistance Protection performance). The maximum oil film polarization resistance and the intermolecular interaction energy of the molecular weight of the commonly used lubricating additives were investigated experimentally and theoretically. The results show that the smaller the intermolecular interaction energy is, the larger the polarization resistance of the oil film containing the additive oil film is, and the better the protective performance of the oil film against metal corrosion is.
