| 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: | According to the equal interval gray forecast GM(1,1) model,an unequal interval gray forecast GM(1,1)model was established.This model can be applied in forecasting the sub-sequent corrosion status of gas pipeline.Through an analysis of the original date of the corrosion index,it is proved with an example that the unequal interval gray forecast GM(1,1)model can enlarge the application of an equal interval gray forecast model.The same accurate forecast can be made under the condition of a small sample,thus providing a dependable basis for preventing gas pipeline from corrosion. |
