采用灰色系统理论中灰色动态模型GM(1,1)的改进模型,对储罐实际统计的腐蚀速率数据进行灰色动态模拟,建立了相应的预测方程。对储罐罐顶、罐壁和罐底板的腐蚀速率进行预测,结果表明:预测值与实际值吻合较好,预测方程具有很高的稳定性和精确性。该预测方程可利用较少的实际数据进行储罐各部分未来任意时刻的腐蚀速率预测,从而为储罐的腐蚀防护和安全管理提供科学依据。 An improved model of gray dynamic model GM (1,1) in gray system theory is used to simulate the actual statistical corrosion rate data of tank, and the corresponding prediction equation is established. The corrosion rates of tank top, tank wall and tank bottom are predicted. The results show that the predicted value agrees well with the actual value, and the prediction equation has high stability and accuracy. The predictive equation can predict the corrosion rate of any part of the storage tank at any future time with less actual data so as to provide a scientific basis for the corrosion protection and safety management of the storage tank.
