在实验室中通过模拟装置对 Q2 35钢在土壤中的宏电池腐蚀行为进行了研究。结果表明 ,饱和 /非饱和土壤环境的差异对金属的宏电池腐蚀具有决定性的作用 ;土壤的电阻率可以影响宏电池的电流分布 The macro cell corrosion behavior of Q235 steel in soil was studied in a laboratory by a simulator. The results show that the difference of saturated / unsaturated soil environment plays a decisive role in the macro-cell corrosion of metal; the resistivity of soil can influence the current distribution of macro-battery
