| 摘 要： | 锌在KOH溶液中是不稳定的，会发生电化学腐蚀，即锌的阳极反应与水的阴极反应组成的共轭析氢反应，所以锌在碱性溶液中属于析氢腐蚀。讨论了影响锌腐蚀的因素，锌在碱性溶液中的腐蚀速度与温度、KOH溶液的浓度及电解液的组成（含ZnO及其添加剂）等因素有关。锌的析氢腐蚀速度可用简单有效的量气法来测量，并介绍了几种可振动且分刻度为0．05mL的简单量气管。

| Abstract: | Zinc is unstable in KOH solution.Zinc electrochemical corrosion is occurred.H2 is evolved.The factors of influence on zinc corrosion are discussed,the corrosive speed relates to temperature, concentration of KOH solution, and electrolyte composition etc.. The corrosive speed is measured by measuring gas method,the method is simple and effective for zinc corrosion in alkaline electrolyte.The new measuring gas tube was suggested,the tube can be vibrated and its measuring graduation are 0.05 mL. |

| Keywords: | Zinc corrosion measuring gas method zinc electrode alkaline Zn/MnO2 battery |
