| 摘 要： | 在氟硼酸盐溶液中，以蛋白胨为添加剂，在铅锡合金电极上用恒电流法和电位扫描法研究铅锡的阴极过程，测定了合金的极化曲线和各金属的分极化曲线。结果表明金属的沉积过程受到电荷传递步骤的控制。测得ａ＝０．１４。证实氟硼酸本身不直接参加电极反应，但反应速度常数Ｋｆ与酸浓度成正比。

| Abstract: | The cathodic process of tin and lead was investigated on polycrystalline Sn- Pb alloy electrode by galvanostatic and potential sweep methods in a fluorobo- rate solution with poptone additive. Polarization curve of the alloy and partial polarizatiom curves of various metals were determined. The result showed that clectrodeposition process of the alloy was controlled by the charge transfer step. The value a was determined to be 0.14. It was confirmed that electrode reaction proceede without the direct participation of flooroboric acid itself, but the reaction rate constant K was directly proportional to the concentration of flooroboric acid. |
