辐照环境中ZnO类热控涂层性能退化预示模型研究

The forecasting models for the solar absorptance of ZnO-type thermal control coatings in the space combined radiation environment

文章研究ZnO类热控涂层在空间综合辐照环境下太阳吸收率(αs)退化的预示模型。利用ZnO类热控涂层的空间综合辐照环境试验数据,对比分析6种数学模型分别拟合出的αs退化预示结果。结果表明,选择合适的预示模型,可以大幅缩短试验时间,利用预示数据就能较准确地反映出αs的退化情况。

The forecasting models for the solar absorptance (αs) of ZnO-type thermal control coatings in the space combined radiation environment are studied. Six forecasting models are used to predict the change of αs in related conditions according to the experimental results. The regression curves arc obtained. It is concluded that one of the forecasting models is more preferable for estimating the change of αs than the others.
