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。
In this paper, the predictive model of degradation of solar absorptance (αs) of ZnO-based thermal control coatings under space-comprehensive irradiation was studied. Based on the experimental data of space radiation environment of ZnO thermal control coating, the results of αs degradation predicted by the six mathematical models were compared and analyzed respectively. The results show that the selection of a suitable model can significantly shorten the test time, the use of predictive data can more accurately reflect the degradation of αs.
