对一维半透明平板内辐射、导热及边界对流耦合换热过程进行了研究。提出了一种由一侧边界出射辐射强度反演另一侧边界入射辐射热流密度的方法。通过对各向异性散射、吸收系数、散射系数、边界外侧来流温度、对流换热系数、半透明平板的导热系数和平板厚度等参数对反演精度影响的分析表明，方法是可行的。 The radiation, thermal conduction and boundary-convection heat transfer in a one-dimensional semi-transparent slab were studied. A method was proposed to retrieve the heat flux density of incident radiation on the other side from the radiation intensity of one side boundary. The analysis of the influence of anisotropic scattering, absorption coefficient, scattering coefficient, outflow temperature, convective heat transfer coefficient, thermal conductivity and slab thickness of translucent slab on the inversion accuracy shows that the method is feasible.
