| 摘 要： | 根据等时距GM(1,1)模型建立了不等时距GM(1,1)预测模型,该模型可应用于利用腐蚀指标的原始数据来预测以后的输气管道腐蚀情况。验证表明,不等时距灰色模型扩大了等时距灰色模型的应用范围,在小样本的情况下同样可以做出较准确预测,为输气管道的防腐提供了可靠的依据。

| Abstract: | The unequal interval gray forecast GM(1,1) is established according to the equal interval gray forecast GM(1,1) model.This model can be applied to forecasting the sub-sequent corrosion status of gas pipeline through the original data of the corrosion index.It has been proved that the unequal interval gray forecast GM(1,1) model enlarged the application range of equal interval gray forecast model.The accurate forecast can also been made under the condition of small samples,which provides dependable evidence for corrosion protection of gas pipeline. |
