灰色动态模型在预测输气管道腐蚀中的应用

在输气管道中，引起腐蚀的因素很多，并且复杂。腐蚀速度和腐蚀深度是随时间而变化的灰色量。为了对输气管道的腐蚀状况进行预测，掌握输气管道腐蚀的基本规律，应用灰色系统理论中的模型对输气管道的腐蚀速度和腐蚀深度等指标的实际统计数据进行了灰色动态拟合，建立了相应的灰色微分方程和灰色时间响应函数；并在此基础上对四川输气管道的腐蚀速度和腐蚀深度进行了预测，为输气管道的防腐提供了切实可靠的依据。

APPLICATION OF GRAY DYNAMIC MODEL IN PREDICTING CORROSION OF GAS PIPELINE

In gas pipeline , many factors can cause corrosion and are very complex.Corrosion rate and corrosive depth are gray varibles with time.In order to predicting corrosive condition and mastering the fundamental corrosive law in gas pipeline,this paper matched the statistical data of corrosive rate and corrosive depth by using GM model in gray system theory,and built the corresponding gray differential equation and gray time responding function,corrosive rate and depth in Sichuan gas pipeline have been predicted according to the method.The results are very well and provide the reliable basis for the corrosion-proof of gas pipeline.
