介绍了模拟空间辐照环境对卫星用掺铈玻璃型第二表面镜光(热)学性能的影响。对导电型和非导电型两类掺铈玻璃第二表面镜进行了模拟空间辐照试验。试验项目包括真空中的紫外辐照、真空中两种能量的电子和两种能量的质子辐照。经过相当子同步轨道卫星南北极处7年剂量总和的紫外、电子、质子辐照后,导电型掺铈玻璃第二表面镜的太阳吸收率从0.081上升到0.105;法向发射率从0.84下降到0.80,非导电型掺铈玻璃第二表面镜的太阳吸收率从0.085上升到0.092;法向发射率从0.85下降到0.82。
The effect of simulated space radiation environment on the optical (thermodynamic) performance of the second surface of the cerium doped glass substrate for satellite was introduced. Conducted and non-conductive two types of cerium doped glass second surface mirror simulated space irradiation experiments. The pilot projects included UV irradiation in vacuum, two energy electrons in vacuum, and two energy proton radiation. The solar absorptance of the second surface mirror of the conductive cerium-doped glass increased from 0.081 to 0.105 after the irradiation of ultraviolet, electron and proton at the 7-year dose of the equivalent orbiting satellite at the north and south poles. The normal emissivity decreased from 0.84 0.80, the solar absorptance of non-conductive cerium-doped glass second surface mirror increased from 0.085 to 0.092; the normal emissivity decreased from 0.85 to 0.82.
