摘　　要：在铜材作为主接地网材料的情况下,不少电气工程反映,在接地网附近埋地的钢结构、管道以及混凝土内部钢筋等铁制(电气附属的)设备都存在有严重的腐蚀现象。从本质意义上看,这是一个化学问题。因此,论文从化学中最经典的锌铜原电池反应公开实验课入手,尝试站在化学科学的角度上,来探索和解决这一"电气问题"。In the case of copper as the main grounding grid material, many electrical engineering reflect that there are serious corrosion phenomena in the steel structure, pipeline, concrete internal reinforcement and other iron(electrical auxiliary) equipment buried near the grounding grid. In essence, this is a chemical problem. Therefore, starting from the most classic open experiment course of zinc copper primary battery reaction in chemistry, this paper attempts to explore and solve this "electrical problem" from the perspective of chemical science.
