摘　　要：通过建立热辐射在介质表面散射的微观物理模型,数值模拟了任意入射角下热辐射散射的电场强度分布图形,得到了在任一入射角下的反射角及折射角.模拟结果与经典公式推导的结果吻合得很好,表明所建立的模型揭示了热辐射在介质表面反射及折射的微观机理.A micro physical model to describe the thermal radiation scattering on the interface between two homogeneous media was established, the spacious profiles of electric intensity at any incident angle and the reflection/refraction angles were numerically simulated. The comparison of numerical results with experimental ones indicates that the simulation is in good agreement with the classic principles, which indicate that this model can explain the micro-mechanism of reflection and refraction on the interface between two media.
