摘　　要：作为一种重要的研究方法,类比研究方法被广泛的采用。到目前为止也没有发现磁荷,而磁荷理论就是类比电场的理论提出的。电场也可以类比磁场,从而通过磁场的理论来分析电场。通过严格的数学推导,我们得到电偶极子产生的电场可以表示为一个矢量的旋度的形式。与磁偶极子产生磁场的形式类似,所以磁偶极子模型在磁场中的应用都可以推广到电偶极子在电场中的应用。用此方法,我们计算了电偶极子在电场中的能量和受到的力矩、极化电介质和偶层产生的场。As an important research method,analogical research methods are widely used in various fields. The theory of magnetic charge is provided from the electric field theory though there is no evidence hinting at the existence of magnetic charge.Through reverse analogy, we can also study magnetic fields by the electric method. Through rigorous mathematical deduction,we obtain the electric fields of the electric dipole, which can be expressed as the rotation of a vector potential. Similar to the mechanism of the magnetic dipole producing magnetic field, the electric dipole has the same position in electric field as the position of the magnetic dipole in magnetic field. In this way, we analyze the energy and torque in the static electric field, and the electric field for the polarized dielectric medium and the dipole layer.
