5mol/L NaCl, NaHCO_3+NaCl and NaNO_2+NaCl solutions were selected as the studied media and the effects of the Q235 (A3) electrode area on EN were studied by EN measurements and other traditional .
本文选择A3钢电极及中性NaCl溶液体系、NaHCO_3+NaCl点蚀体系、NaNO_2+NaCl的缓蚀体系,通过电化学噪声测量和多种噪声数据分析方法,研究了电极面积对电化学噪声的影响,主要结果如下:(1)A3钢电极在中性的NaCl溶液体系中,电流电位噪声的标准偏差σ_i、σ_v与电极面积S的关系为: lgσ_i= 0。
