利用武汉地区2002-2007年二氧化硫和氯化物含量数据,建立了这2种典型大气腐蚀介质的GM(1,1)预测模型,探讨了不同维数GM(1,1)模型预测结果的差异.另外,对这2种典型大气腐蚀介质GM(1,1)模型进行了检验,结果表明,GM(1,1)模型的预测精度较高,精度检验等级达到1级.%GM(1,1) prediction models were established, which was based on the data of sulfur dioxide and chloride contents from the year 2002 to 2007 in Wuhan. The differences among different dimensions GM(1,1) model prediction results were investigated. Moreover, the GA/(1,1) models of the two typical atmospheric corrosion mediums were tested. The result showed that GA/(1,1) model has high prediction accuracy, and the accuracy class achieves level 1.
