【摘要】 该文根据天空亮度分布的特征量,除特殊天气现象外,将实际天空分成4类。并从同一地点同一时刻天顶亮度与天空漫射光照度比值出发,在分形理论和人工神经网络理论等基础上,利用信息法确定天空相对亮度分布表达式。最后计算出该比值随时间变化过程的分维值,证明了本文建议的天空分类是合理的,并可以根据实际需要将4类天空分成更多的天空类型。更多还原

【Abstract】 Except phenomena of special whether, this paper divide real shy into four types based on the characteristic variable of sky luminance distribution . According to sky zenith luminance and sky diffuse illumination at same time and same place and the Fractal theory and Artificial Neural Network theory, conform the expression of sky relativity luminance distribution by the way of information. Final this paper calculated the Fractal dimension value changed because of time variety, and demonstrated the reasonable of sky classify that suggested by this paper, and divide the four sky type into more sky style according to real demands.更多还原
