常見例句雙語例句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)測量系統(tǒng)，通過對物體表面雙向反射分布的測量來獲得其方向發(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造成的誤差。Bidirectional reflectance distribution function (BRDF) models treat plant density and optical properties differently and, therefore, can help to assess plant condition objectively.二向反射分布函數(shù)BRDF模型把植物密度和光學(xué)特性區(qū)別對待，因而它有助于植物狀況的客觀評估。 返回 bidirectional reflectance
