摘　　要：利用分光光度计对建筑材料表面,对紫外到近红外线范围(240～15000nm)内的正分光透射比、正分光反射比进行测定。另外,还利用积分球对紫外到红外线范围(240～2200nm)内的漫射比谱进行测定,同时将测定结果与正分光透射比、反射比进行比较,并计算出太阳吸收比及热放射比。The normal transmittance and near normally specular reflectance of ultra-violet, visible and infrared area （240- 15000nm） for building material surface were measured with spectropnotometer, and the diffusion spectrum of transmittance and reflectance of ultra-violet, visible and infrared area （240-2200nm） were measured with integrating sphere The result was compared with the normal transmittance and the normal spectrum reflectance. Based on the measurement resuit, the absorption and emission ratio of solar radiation was calculation and studied.
