摘要
用ＧＭ（１１）模型、指数回归模型及幂函数回归模型对低合金钢大气腐蚀速率进行了拟合及预测，分析表明３种模型都可拟合低合金钢户外暴露１～４年的腐蚀速率，但是只有幂函数回归模型可以预测低合金钢８年的腐蚀率．
The results obtained by GM(11) model analysis. exponent regression analysis and power regression analysis using test data of low alloy steels for one to four years, showed that all the three methods can be used to fairly well reproduced the given test data, but only the power regression analysis is able to predict the eight years corrosion rates of low alloy steels.
