中文摘要：

采用线性电位扫描（LSV）、交流阻抗（EIS）法研究了纯铅、纯锡、铅锡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，锡电极上的析氢电流大于铅，铅锡电极析氢速率的不同主要是由于电化学传递速度的不同；进一步实验数据可知，随着锡含量的增加，析氢反应的电化学电阻减小，氢气的析出电流增大，掺锡加快了氢气的析出。

英文摘要：

Hydrogen evolution behavior on Pb-Sn alloys in sulfuric solution were studied byinear sweeping voltammetry and electrochemical impendance. The results showed that the current of hydrogen evolution on tin was larger on lead, the velocity of electrochemical transfer of hydrogen evolution was diffrent on lead and tin. The experiment data indicated further ,with the increasing of tin content , electrical current of hydrogen evolution increased. And the electrochemical resistance of hydrogen evolution would decrease, with its content increasing, tin would improve hydrogen evolution in the alloy.
