【摘要】 利用RAPIDC(发展中国家区域大气污染)腐蚀子项目的最新试验结果,结合灰色关联分析和非线性回归方法,建立了基于大气腐蚀机理的碳钢、Zn、Cu的腐蚀剂量响应函数.结果表明,获得的剂量响应函数能较好的拟合原始试验数据且形式相对简练,适于区域性的材料大气腐蚀经济损失核算.更多还原

【Abstract】 Based on recent results of a corrosion project,which was a sub-project of the international cooperation programme RAPIDC(Regional Air Pollution in Developing Country),Dose-response functions(DRFs)of carbon steel,zinc and copper were set up by the combined methods of grey relation analysis and non-linear regression.The DRFs could reflect the mechanism of atmospheric corrosion by some extent.The results showed that the obtained DRFs well fitted the experimental data and had relative simple expression,therefore they could be used to calculate the economical loss of material corrosion at regional scale.更多还原
