摘　　要：采用线性电位扫描(LSV)、交流阻抗(EIS)法研究了纯铅和铅钐合金电极在硫酸溶液中氢气的析出。由线性电位扫描和交流阻抗法可知,铅钐电极上的析氢反应的电化学电阻增大,氢气的析出电流减小,说明掺钐减慢了氢气的析出。Hydrogen evolution behavior on pure Pb and Pb-Sm alloys in sul{uric solution were studied by linear sweeping voltammetry and electrochemical impendance methods. The results showed that the electrical current of hydrogen evolution decreased on Pb-Sm alloys, and the elec- trochemical resistance of hydrogen evolution would increase on Pb-Sm alloy. It was indicated that Sm improved the hydrogen evolution in the alloy.
