【摘要】 从麦氏微分方程组出发，推导了双层大地数学模型下垂直电流在空间各点产生的磁矢量势及感应地电位的计算公式，并对公式进行了讨论，给出了几仲典型情况的计算结果及输电线短路状况下一些重要性质。更多还原

【Abstract】 In this paper,based on the Maxwell’s equations,we obtained the calculation formulas of magnetic potential vector and inducted earth POtential of a finite vertical current on the two-layer earth,and aye a discussion onthe formulas.By using them,we discussed some examples which showed some important features when short circuitoccurred in a transmission line.更多还原
