摘　　要：利用不同惯性系之间电磁波传播矢量的相对论变换，推导了电磁波在运动媒质中传播的相速和群速。The phase velocity and group velocity of electromagnetic waves in moving media are derived by relativistic transformation of electromagnetic waves propagation vectors between two inertial frames and their relation and difference are discussed.

关 键 词：相速 群速 电磁波 运动媒质
