摘要: 从均匀外电场中介质球颗粒内外电势分布出发,讨论了介质球在基质中的等效电偶极矩,并进一步分析了等效电偶极矩的物理本源.

关键词: 介质球, 极化电荷, 等效电偶极矩

Abstract: Based on the spatial distribution of electric potential of a dielectric sphere embedded in a matrix, the equivalent electric dipole moment and its origin are investigated when the uniform electric field is applied.

Key words: dielectric sphere, polarization charge, equivalent electric dipole moment
