摘　　要：通过构建模型评价标准进行模型性能综合评价,根据评价指标将模型性能状况分为3个级别,在模型性能状况达到不同级别时分别采取化验值校正、参数校正及模型重构等手段进行模型校正。通过模型校正技术保证了模型预测结果的精确性,增强了腐蚀结垢预测结果的可信度。Through establishing the model evaluation criteria for comprehensive assessment of model perform- ance, the model＇ s performance status was divided into three levels; and the model calibration was carried out through calibrating laboratory values, parameters and model reconstruction when the model performance status reached different grades. The model correction technique can ensure accuracy of prediction results of the model and enhances the credibility of corrosion scale prediction results.
