极化强度矢量与磁化强度矢量的相对论变换的直接推导

A DERIVATION OF THE RELATIVISTIC TRANSFORMATIONOF POLARIZATION VECTOR AND MAGNETIZATION VECTOR

本文运用电磁场量的矢量变换式 ,直接推导极化强度矢量P 与磁化强度矢量M 的相对论变换关系 ;并进一步证明了P 与M 构成的介质极化———磁化张量Mμν可构成两个洛伦兹不变量 .

The transformation of polarization vector and magnetization vector is derived by the vector transformation of electromagnetic field and thereafter two Lorentz invariants containting P and M are proved.
