摘要
城市地下输电线路断开后,会与潮湿土壤中处于地上或地下的铁轨(管线)形成回路,加快铁轨(管线)腐蚀。该原理相当于将串联电解池的电解质溶液合并,两池中非连接电源的两电极合为一导体平放于连接电源的两极之间,形成一个特殊的串联电解池。基于以上内容,创新了实验。
When the city underground transmission line was disconnected, it would be in line with the track (pipeline) on the ground or underground in wet soil to form a circuit, and sped up the corrosion of tracks (pipelines). The principle was equivalent to the combination of electrolyte solution of series electrolytic cells in which two electrodes without connecting power supply were as a conductor laied between the two electrodes connecting power supply, then formed a special series electrolysis cell. Based on the above principle, this paper designed innovative experiments.
