电矩P和Q在各向异性电介质中的电场

Electric Field of Dipole Moment and Quadrupple Moment in Anisotropic Media

把各向异性电介质中静电势的解给出的点电荷在各向异性电介质中的电势公式，表成在各向异性直角坐标系中的形式．求得在此坐标系中电偶极矩（P）的电场，并通过坐标变换得到电偶极矩在各向异性介质中的电场．最后将此方法由电偶极矩推广到电四极矩（Q）．

The electric potential equation of point charge in anisotropic media is expressed in the form ofanisotropic rectangular coordinate. In this coordinate. the electric field of dipole moment is calculated: andthe electric field of anisotropic media is derived by coordinate transformation. The method can be extendedfrom dipole moment to quadrupple moment.
