摘　　要：基于沿任意方向运动坐标系间的Lorentz变换矩阵,以及电磁场的状态方程和本构关系,得到了平面波入射下多层运动介质任意方向运动时电磁波的传播特征.结果表明:沿任意方向运动多层介质内,每层介质层的能流密度与其相对折射率、相对磁导率和运动速度有关,任意第l层和第l+1层电磁波能流密度的表达式有传递关系.Based on Lorentz matrix transformation between two coordinate systems moving relatively in arbitrary direction and by using state equation and constitutive relationship of electromagnetic fields, the propagation characteristics of plane electromagnetic wave incident upon a layered medium moving in an ar- bitrary direction is obtained. The result shows that within the multilayer medium moving in arbitrary di- rection, the energy flux density of every medium layer will be dependent upon its relative moving layered medium has tightly conaection with relative refractivity relative magneto conductivity, and moving veloci- ty, and there will be a transitive relation of the expression for electromagnetic energy flux density between lth and （l＋1）th layers.
