摘　　要：简述了几种镀铬理论的发展过程,对霍尔理论提出质疑,认为存在一个化学转化步骤,硫酸与铬酸反应生成硫酸铬酰,铬氧基是阴极放电离子。The development process of several chrome theory is summarized,and the Hoare Theory is to be criticized.It is believed that there is a chemical reaction,which sulfuric acid reacted with chromic acid and then chromium sulfate acyl is generated.The chromium oxygen group is the discharge ion on the surface of the cathode.
