在实验室配制不同含水率土壤介质，利用线性极化及电化学阻抗技术，测试了Q235钢在冻土环境下的线性极化曲线和交流阻抗曲线，并对测试结果进行了分析拟合，得到线性极化电阻值和电荷转移电阻值，并与常温下Q235钢的腐蚀行为进行了对比，从而确定了Q235钢在不同含水率的冻土环境中的自腐蚀电位值以及Q235钢的腐蚀情况。
在實驗室配製不同含水率土壤介質，利用線性極化及電化學阻抗技術，測試瞭Q235鋼在凍土環境下的線性極化麯線和交流阻抗麯線，併對測試結果進行瞭分析擬閤，得到線性極化電阻值和電荷轉移電阻值，併與常溫下Q235鋼的腐蝕行為進行瞭對比，從而確定瞭Q235鋼在不同含水率的凍土環境中的自腐蝕電位值以及Q235鋼的腐蝕情況。

The linear polarization curves and Electrochemistry plots were measured in different containing water ratio at 0℃and-5℃in laboratory. The linear polarization and Electrochemistry results were achieved through analyzing the curves and plots. They were compared with the results which were measured at 23℃and 5℃in different containing water ratio, consequently the self-corrosion potential and corrosion behavior of Q235 steel in different containing water were confirmed.
