For controlling light pollution and protecting the dark sky resource,origin of sky glow from the atmosphere dispersion was analyzed,research progress and primary results on night sky brightness models,including a model between night sky brightness and the urban population,the distance and a model between night sky brightness and dispersion forms,were discussed.
文章从防治光污染、保护暗天空资源的角度,理论分析了夜天空发亮的原因,讨论了夜天空亮度分布模型的研究进展和主要成果,其中主要包括夜天空亮度与城市人口、距离变化关系的模型以及夜天空亮度与散射方式关系的模型,并进一步提出了城市夜天空保护方面深入研究的理论框架。
This paper suggests the formula about sky luminance distribution on pseudoovercast sky.
本文提出了似阴天空亮度分布表达式,经验证表明,它与天空亮度实测结果吻合较好。
It also is a good method to study sky luminance distribution.
本文建议了一种确定天空亮度值的新方法,它的优点是同时性好,因而也是一种研究天空亮度分布的好方法。
