前言现代空间技术,对隔热材料的重量提出了严格的要求。为了适应这一要求,国外在五十年代末和六十年代初应用和发展了轻质高效的Min—K材料。它在空间技术方面得到了一定的应用。本课题研制的超低导热系数高温隔热材 Preface Modern space technology sets strict requirements on the weight of insulation materials. In order to meet this requirement, foreign countries in the late fifties and early sixties applied and developed a lightweight and efficient Min-K material. It has some applications in space technology. The subject developed by the ultra-low thermal conductivity of high temperature insulation material
