| 摘 要： | 新型的多孔材料以其重量轻、强度高备受航天工程设计人员的亲睐,尤其是作为隔热材料使用,可以说是航天工程热防护系统的热门材料.多孔介质在辐射热传递方面具有吸收发射和散射的功能,这些功能在其接受外来热流的作用下,于内部达到热能量平衡,求解这一平衡方程就可以求出辐射热流在材料中的分布.由于求解这一方程的困难,许多学者对材料特性...

| Abstract: | In the light of the light weight and high strength of the new type of porous materials,it is favoured by the designers of aerospace engineering,especially when it is used as insulation material,hence it can be reckoned as a demanding material in the heat protection systems of aerospace engineering.Radiative heat transfer associate with a porous medium consists of heat energy absorption,emission and scattering,which attain equilibrium under the external heat.Because of the difficulties in solving this equili... |
