【摘要】 分别用灰色GM(1,1)模型、幂函数模型对铝电解惰性阳极腐蚀试验数据进行了拟合和预测,结果表明:采用灰色GM(1,1)模型进行预测,只有在电解过程平稳,预测时刻比较近的情况下,才有一定的命中率,对于较长时刻的腐蚀失重预测,误差较大;幂函数模型的拟和精度较高,但其外推误差较大。更多还原

【Abstract】 The grey model GM (1, 1) and power function model were established with corrosion rates of inert anodes for aluminum smelting. The results of fitness and prediction show that for smooth aluminum smelting processes, the GM (1, 1) model has good prediction accuracy in a short term, while the model is not suitable for the corrosion rates prediction in a long term because of its poor flexibility and accuracy. The power function model has relative good fitness accuracy, while the extrapolation accuracy is poor.更多还原
