摘要:探讨了“接地电阻”名称之来源,用科学方法论评审其定义之缺陷,实践表明,这
个物理量是不可能获得确定值的,在工程技术上采用它,既无科学根据又造成极大损失
及危害。

Abstract: The source of the term “ground resistance” was delved into. Some
definitions of such quantity were examined with scientific methodology. The
practice and experiments showed the determination of this quantity did not
posses repeatability. The use of this quantity led to heavy losses
Key words: ground resistance; Ohm’s law; scientific experiment
