| 摘 要： | 根据Q235钢在海南地区第2年的土壤腐蚀试验结果,以及对各试验站土壤化学成分的分析,采用逐步回归的统计分析方法,讨论土壤化学成分与Q235钢腐蚀失重的相关关系。结果表明,土壤中的Ca~(2+)和全氮量与Q235钢的腐蚀失重有较好的相关性,是Q235钢腐蚀的主要影响因素。

| Abstract: | According to the testing results of soil corrosive of Q235 steel second year in Hai Nan and the analysis of soil chemical composition from all test stations.The Correlaleoit between the soil chemical composition and corrosion and corrosion weight loss of Q235 steel was discussed by skepwise regression.The resuts showed that Ca~(2+) and pan nitrogen in soil with corrosion weight loss of Q235 steel have better relativity.Ca~(2+) and pan nitrogen are main influencing factors of Q235 steel corrosion. |
