为了节约国家铜料,我队采用了钢电极作为测量MN 电位差的测量电极,效果良好。最近我队还进一步在实验室内做了一些分析和试验工作,更足以证明以钢代铜是可以的,丝毫不影响质量,并有经济耐用及减少接地困难等优点。在电法工作中,测量线路上的 MN 接地,习惯上均采用紫铜棒。根据经验,纯铜具有较稳定的化学性,有较小而稳定的极化电位,可使 MN 电位测量更为准确。但实际工作和试验表明,质量较纯的钢电极的极化亦很稳定。此外,铜电极价格贵,质较软损坏率很高等,在这些方面是不如钢电极的。在党的总路线光辉照耀下,八届八中全会精神鼓舞下,为了节约国家铜料,在大队党委指示下,实验室对"钢电极代替 In order to save the national copper material, our team adopted the steel electrode as the measuring electrode for measuring the potential difference of MN, and the effect is good. Recently, our team has further done some analysis and test work in the laboratory, which is enough to prove that it is possible to replace copper with steel without any impact on quality, economy, durability and reduction of grounding difficulties. In the work of the electrical method, the MN on the measurement line is grounded, and copper rods are conventionally used. According to experience, pure copper has a more stable chemical, with smaller and stable polarization potential, MN potential measurement can be more accurate. However, the actual work and tests show that the polarization of the purer steel electrode is also very stable. In addition, the expensive copper electrode, the quality of soft damage rate is high, in these areas is not as good as the steel electrode. Inspired by the spirit of the 8th Plenary Session of the Eighth Central Committee under the shining spirit of the party’s general line, in order to save the country’s copper material, the laboratory, on the instructions of the party committee of the brigade, replaced the steel electrode
