摘要
利用试验获得结果作为建模样本,采用逐步回归分析法(线性)对管线钢的腐蚀速率建立了预测模型,用VB6.0编制了程序进行计算与预测。将模型预测结果与现场实测的数据进行对比,考察模型的合理性。经分析,发现此模型适用范围不同,在一定程度上预测准确,误差在可接受范围内。
Using thetest results as modeling samples, using stepwise regression analysis (linear) of pipeline steel corrosion rate prediction model is established, the calculation and prediction program was compiled with VB6.0. The model predicted results with thefield measured data are compared, the rationality model. Through analysis, this model is found to accurately predict the scope of different, to a certain extent, the error is in the allowable range.
