摘　　要：提出了一个计算丝网辐射特性的方法,既考虑了散射,又考虑了表面性质的影响。利用了分层迭加原理及双通量模型。计算结果与投影理论及Mie电磁散射理论的结果作了对比。用高温风洞实验进行了旁证。A method for calculating the radiation properties of wire meshes is presented, in which the effects of scattering and surface characteristics are both taken into consideration, and the stratified superposition principle and a double flux model are employed. Finally the calculated results are compared with those obtained by projective theory and Mie electromagnetic theory, and confirmed by a high temperature wind tunnel experiment. It is shown that the results by this method coincide with the experimental results well.
