摘要: 主要通过灯丝放电磁场约束型原子氧剥蚀效应地面模拟设备模拟空间环境,对空间常用材料Kapton进行了原子氧剥蚀效应、温度升高对材料原子氧效应的影响试验以及原子氧与紫外辐射复合效应试验,对试验前后试样的外观、质量及表面形貌进行了比较,得出了材料在设备中的反应特点以及温度变化、紫外辐射对材料的原子氧效应的影响规律.同时测量了原子氧暴露试验前后、原子氧与紫外辐射复合作用前后试样的反射率和透射率,并进行了比较.Abstract: Experimental investigations of atomic oxygen, temperature rise, ultraviolet radiation effects on Kapton, a spacecraft material in common use, were conducted using atomic oxygen effects ground-based simulation facility. The samples aspect, mass and surface morphology before and after experiment was compared in this thesis. Reaction characteristics of Kapton in the facility and influence rule of temperature change as well as ultraviolet radiation on atomic oxygen effects of Kapton were acquired. Optical properties, such as reflectivity and transmissivity, before and after experiments were measured and compared.
