摘　　要：通过比较30Cr2MoV汽轮转子钢分别在苦味酸溶液和硫酸酒精溶液中动电位阳极极化行为,发现在2种腐蚀液中建立的3个不同的FATT预测模型拟合误差分别为±20℃、±25℃和±15℃,后一种溶液要精确一些。而且在安全性方面,硫酸酒精溶液要比苦味酸安全许多。It is found that the FATT predicating equations of 30Cr2MoV turbine rotor steel, tested in picric acid solution and the admixture of aulfuric acid and alcohol, fall in ＋ 20℃, ＋ 25℃, and ＋ 15℃, and we know that it is move accurate when tested in the latter solution, what＇s move, the latter one is much move safer than the former one.
