摘　　要：在大学普通物理的电磁学部分,讨论静电场与电介质之间的相互作用时,引入了一个辅助物理量———电位移矢量(D).在一般的电磁学教学参考书以及电动力学中,很少对其意义进行深入的讨论,笔者从电位移引入的历史出发,根据电位移的定义式,对电位移矢量的意义进行深入的剖析,给出具体的物理意义.In the section of electromagnetism in College Physics, the electric displacement vector(D), is often introduced as an auxiliary physical concept through the studies on the interaction of electrostatic field and dielectric. However, the meaning of electric displacement vector is seldom expounded deeply in general electromagnetism references and electrodynamics. Basing on the history and definition formula of electric displacement, this paper makes a careful analysis of the meaning of electric displacement vector and presents its physical meaning.
