摘要
本文对北京、青岛、江津、武汉地区的耐候钢和碳钢的大气腐蚀数据进行了方差分析。研究发现在北京地区两类材料的大气腐蚀数据无显著差异,在青岛、江津、武汉地区耐候钢腐蚀率显著低于碳钢。通过对北京地区耐候钢和碳钢的回规分析,得出两类材料的腐蚀数据和腐蚀时间之间遵循线性双对数规律,并根据回规方程对耐候钢与碳钢在北京地区的大气腐蚀进行了预测。
Discuss the variance analysis of atmospheric corrosion at BEIJING,QINGDAO, JIANGJIN and WUHAN of weathering and carbon steel, No 'Significant Variance' has been observed between atmospheric corrosion date of weathering and carbon steel at BEIJING.Regression analysis of atmospheric corrosion date at BEIJING shows that relationship between corrosion date of weathering and carbon steel and time follows linear bilogarithmic law. According to regression equation, the atmospheric corrosion of weathering and carbon steel at BEIJING may be predicted.
