摘　　要：为了研究气候环境因素对金属腐蚀速率的影响,推测它们的量化关系,以碳钢为例,将数据挖掘的方法应用于大气腐蚀试验站点的腐蚀速率数据和气候环境数据,建立了大气环境中推测碳钢腐蚀速率的模型,并得出腐蚀速率推测公式。腐蚀站点试验数据的验证结果表明:该方法有较高的推测准确度,对于全面了解我国不同地区的碳钢腐蚀状况具有指导意义。In order to study the influence of climatic and environmental factors on corrosion rate, and the quantitative relation between climatic and environmental factors and corrosion rate, carbon steel was chosen as sample, and the method of data mining was applied to the data of corrosion rate and environmental factors from corrosion sites. A mathematical model to speculate the corrosion rate based on climatic and environmental data was set up and speculation formula was obtained. The results show that this model can speculate the corrosion rata of carbon steel with a high accuracy, and it can help us to fully acquaint the corrosion status in different regions.
