常見例句雙語例句This sphere serves as a diffuse light source, which enables measurements of the hemispherical reflectance, or the directional absorptance, respectively.這個(gè)球作為擴(kuò)散光源，使測(cè)量的半球形或定向吸收率的反射系數(shù)，分別使用。The directional emissivity is deduced from the Bidirectional Reflectance Distribution Function(BRDF)in the hemispherical scattering space of the objects.利用雙向反射分布函數(shù)測(cè)量系統(tǒng)，通過對(duì)物體表面雙向反射分布的測(cè)量來獲得其方向發(fā)射率。Reveals the importance of differentiating bidirectional reflectance factor ( BRF ) from hemispherical reflectance factor and shows the errors caused by the confusion.本文通過分析，說明了區(qū)分雙向反射因子和半球反射因子概念的重要性以及誤用它們所會(huì)造成的誤差。 返回 hemispherical reflectance
