摘　　要：利用分光光度计手段对建筑材料表面进行了从紫外到近红外线范围（240~15 000 nm）的正分光透射比,正分光反射比的测定.另外,还利用特形积分球从紫外到红外线范围（240~2 200 nm）的散射比谱的测定,同时将测定结果与正分光透射比、反射比进行比较.从其结果中算出太阳吸收比及放射比,并对上述结果进行计算分析,以期能有效地利用太阳光能源,达到节能减排的效果.This report is about heat income and expenditure on the surface of the building material.It measured the normal transmittance and near normally specular reflectance of ultra-violet,visible and infrared area(240nm-15,000 nm),Also,it measured the diffusion spectrum transmittance and reflectance of ultra-violet,visible and infrared area(240-2,200 nm) compared with the normal transmittance and the normal spectrum reflectance. From the result of these measurement,it calculated the solar radiation absorption and emission and compared the difference of there values.Namely,the absorption and emission is 0.07 and 0.85 forglass 0.39,0.08 for copper and 0.44 and 0.90 for tile etc.The different characteristics of these building material on radiant environment under solar radiation and in normal room temperature was shown.
