摘　　要：介绍了卫星环模试验中,用作红外辐射定标试验冷背景的低于18 K超大尺寸冷屏的设计方法,详细介绍了冷屏的结构设计、材料的选择、热设计、工艺制造等关键技术。试验应用结果表明,冷屏的实际技术性能指标达到并超过了设计要求。The design of methods of the 18 K super large dimension cro-pannel used for infrared radiation demarcating in space environment simulation test were introudced. The structure of cro-pannel design, the choice of materials, thermal design, manufacturing process development were introudced. Test results show that the actual technical performance indicators of cro-pannel met and exceeded the design requirements.
