摘　　要：对防锈油膜腐蚀电位分布不均匀性及电位服从不连续二项分布进行了理论分析 ,探讨了防锈油膜腐蚀电位分布不均匀性的原因 ,并与实际测量的结果进行了比较 .研究表明 ,理论分析结果与实际测量相符合 .Theoretical analysis of inhomogeneity of corrosion potentials with rust preventive oil film and conformity to discontinuous binomial distribution is described.This paper is on the basis of Bailey and Ritchie's general electrochemical theory for the oxidation of metals.In general electrochemical theory,oxidizing metal is viewed as a self-driving electrochemical cell in which the oxide acts as both ionic and electronic conductor.It is pointed out that theory analysis results are coincident with experimental measurements.There exist two kinds of film in the rust preventive oil film,ionic film and electronic film,which lead to inhomogeneous corrosion potentials distribution on metal surface and discontinuous binomial distribution.
