本文从腐蚀现象论及比例模型,论证了腐蚀现象具有统计性质,指出无论是均匀腐蚀或局部腐蚀,其发生、发展都遵循相应的统计分布规律,并分析了其原因在于材料和腐蚀环境的不均匀性;还指出在研究腐蚀现象时,不能仅从电化学的确定论出发,而必须考虑腐蚀现象的统计性质,才能全面把握腐蚀现象规律。 In this paper, from the theory of corrosion phenomena and proportional model, the phenomenon of corrosion is proved to be of statistical nature. It is pointed out that both the occurrence and the development of the corrosion phenomenon follow the corresponding statistical distribution law, and the reason is that the material is not corrosive to the environment It is also pointed out that when studying the phenomenon of corrosion, we can not only proceed from the determination of electrochemistry, but also consider the statistical nature of the phenomenon of corrosion so as to fully grasp the law of corrosion.
