摘要: 應用灰關聯分析原理討論了海水環境與金屬腐蝕性之間的關系.基于灰關聯度的計算,找出了在全浸帶條件下,海水中對A3鋼具有腐蝕影響的主要因素,利用人工神經網絡BP算法建立了海水環境對A3鋼的腐蝕作用模型,用該模型預測了新海水域環境下金屬的腐蝕速度,取得了較好的結果.Abstract: The relationships between ocean corrosion of metal and the ocean environment were studied by grey relational analysis methods. Under the submergence, the main factors of corrosion for A3 steel in ocean environment were found in accordance with grey relation grade. Neural network was applied to set a madel of ocean corrosion to A3 steel. Then the model is used to predict the corrosion rate of A3 steel in the new ocean environment and a satisfied result is obtained.
