应用弱极化曲线技术和电化学阻抗谱研究了湿度对中性土壤中钢铁材料腐蚀行为的影响结果表明，各种湿度的土壤中碳钢的腐蚀速度和腐蚀电位均随腐蚀的持续进行而趋于一个稳定值，碳钢的稳定腐蚀电流密度随湿度变化丰在最大值，碳钢土壤腐蚀过程与土壤湿度密切相关。
The influences of moisture content on corrosion behavior of carbon steel in neud soil were studied by low-polarization curve technique. It was found that both the corrosion current density and corrosion potential reached a constant value with the development of corrasion of carbon steel in soils with different misture content. ?he invariable soil cormsion current density of carbon steel had a maximum value with the variation of moisture content. At the same time, the controlling characteristic of soil comion is discussed.
