摘　　要：应用时空图法研究光以任意角入射到运动介质表面时沿光线方向的反、折射规律.讨论介质运动速度、界面角度、入射角度对反、折射光线方向的影响.给出低速近似下,反、折射光线方向、频移大小的普遍公式.We investigate the law of reflection and refraction along the direction of propagation of the light ray when the light incident on the surface of moving medium at any angle using the space-time diagram method.The effects on the direction of reflected and refracted rays from the velocity of moving medium,angle of the surface and incidence are discussed.The general formulas of direction and frequency shift of reflected and refracted rays are given in low-speed approximation.
