By using Randles equivalent circuit, the kinetic factors on electrode reaction between the alloy and the salt were obtained, such as electrolyte resistance Re, double-layer capacitance Cd, charge transfer resistance Rct, rate constant of desulfurization reaction Kf and so on. When overpotential η equals to -85 mV, these values are Re=2.93×10-5 Ω.m2, Rct =2.47×10-5 Ω.m2, Cd=1.01 F/m2, Kf=2.1 × 10-3 s-1, respectively. Key words： AC impedance method    Randles equivalent circuit    charge-transfer resistance    double-layer capacitance    salt-metal interfacial reaction 收稿日期: 1998-05-18      基金资助:国家自然科学基金!59404004 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王淑兰 李光强 隋智通 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1998/V34/I5/521 1蒋国昌,徐匡迪,邓健雄.金属学报,1990;26:B33(Jiang Guochang, Xu Kuangdi, Deng Jianxiong.
