空间调制干涉光谱成像仪光谱辐射度定标方法研究

空间调制干涉光谱成像仪不同于其他类型光谱成像仪,其像面上得到一维空间信息和一维光谱信息。由于其原理特殊,定标方法尚不成熟。介绍了一种用于空间调制干涉光谱成像仪光谱辐射度定标的方法,即干涉光谱成像仪和光谱辐射度计同时采集目标辐射强度,复原采集干涉图得到的光谱图,与光谱辐射度计采集绝对光谱进行比对,得到定标系数,并分析了该方法达到的精度。结果表明：该方法可以满足空间调制干涉光谱成像仪光谱辐射度定标的要求,定标精度达到5．74％。     

空间调制干涉光谱成像仪线性度测试

根据线性度分析方法,结合空间调制干涉光谱成像仪的成像原理,建立了线性度测试系统.采用太阳模拟器作为光源,通过减光片得到8个亮度等级的辐射输出,用待测仪器与光谱辐射度计分别对其进行采集,比对得到待测仪器线性度为0.81%,不确定度为2.7%.结果表明：该线性度测试方法精度较高,此方法同样适用于同类干涉光谱成像仪的线性度测试.

经计算推导和实验,研究设计了空间调制干涉光谱仪的星上定标系统,并进行了实验室光谱测试和航天元件的多种环境测试.解决了空间调制干涉光谱仪星上定标技术的关键组件定标光源、光谱滤光片、积分球组件的技术难点.实现了全孔径、部分视场的相对光谱定标,得到了星上定标光谱和干涉图.     

碳离子束辐照处理对牛至精油微胶囊的缓释特性及抗鸡球虫病活性的影响

利用不同剂量的碳离子束辐照处理牛至精油微胶囊,研究对其缓释特性及抗鸡球虫病活性的影响。研究结果表明,通过碳离子束处理的牛至精油微胶囊,其主要活性成分百里香酚和香芹酚含量未发生变化,辐照处理后反应收率及产品的生物活性均提高,其中400 Gy剂量处理的牛至精油微囊的收率和生物活性均最高,收率达68.44%。通过对感染柔嫩艾美耳球虫的小鸡喂食后,其盲肠和十二指肠肿胀明显减轻,血液性内容物明显减少,血便指数在感染的第七天已降为0,抗球虫指数（ACI）达到179.39。The purpose of this study is using different doses of carbon ion beam irradiation on oregano essential oil microcapsules, to investigate function of control release and anticoccidial activity in chickens. The results showed that the content of main components in oregano essential oil microcapsules after carbon ion beam irradiation, thymol and carvacrol, have little change. Moreover, it can obtain more object products and better bioactivity after the irradiation treatment. Among these different doses of irradiation, our findings showed that Microcapsule groups with 400 Gy dose irradiation showed the highest yield (68.44%) and the best anticoccidial activity. After feeding chickens infected with Eimeria tenella, the swelling of caecum and duodenum were significantly mitigated and blood contents were also significantly reduced. The bloody stool index of chickens was as low as zero on the seventh day of infection, and the anticoccidial index (ACI) is 179.39.
