摘    要:长期埋于地下的同轴电缆由于发生了部分形变,其屏蔽层与缆芯之间的恒定电场的电势计算较困难,本文应用有限差分法将场域划分成网格形,经数学处理后,可将场域满足的微分方程转化为线性代数方程组.并用迭代法根据IBM-PC机的计算结果绘制了等势线.

关 键 词:变形电缆;电势;等势线;有限差分法

Abstract:It is not easy to calculate the potential of the electrostatic field between the deformed coaxial cable screening and the core of a deformed coaxial cable, which is buried underground for a long time.We divide the field into a set of nets so that we can use finite difference method to calculate the potential. By using iterative method to solve the corresponding algebraic equations on an IBM-PC,we get a set of equipotential curves.
Keywords:deformed cable  electric potential  net linear equations  finite difference method
