摘要: 利用拉普拉斯方程讨论了球壳介质结构在匀强电场中的静电势分布,结果表明:平行电场线不仅会在介质表面处会聚,而且还可能出现不变,甚至是发散的情形.并采用MATLAB软件对上述情形给与了直观验证.

关键词: 球壳介质结构, 静电势分布, 匀强电场

Abstract: The electric potential distribution of core-shell structured medium in uniform electric field is investigated by solving the Laplace equations. The results show that the parallel electric field lines have three cases nearby the surface of core-shell structured medium, which are convergence, divergence and constant case. Furthermore, the above are tested using MATLAB software.

Key words: core-shell structured medium, distribution of electric potential, uniform electric field
