| 摘 要： | 在分析资源-1（02）卫星多层隔热材料外表面遥测温度数据的基础上，给出了30个月在轨条件下多层隔热材料外表面的温度变化规律与外热流的关系，得出了多层隔热材料面膜表面热光学性质在卫星入轨5天后其性能退化随时间变化很小的结论。并提出了如何对多层隔热材料进行在轨设计和试验的建议。

| Abstract: | On the basis of an analysis of the in-orbit temperature data of CBERS multilayer insulator（MLI） outer surface film, the temperature change rule along with orbit heat flux was found in this satellite orbit. Thirty months＇ data show that the MLI outer surface temperature change with different direction of the satellite and the MLI outer surface thermo-optical property degeneration would not much within 5 days after the satellite has been launched. Advice for thermal design and test of the MLI is given. |
