reflectance coefficient meaning in English

反射系数

Abstract : by means of rds detection system , slight difference of reflectance coefficients for samples can be measured in two mutually vertical directions on the plane of the sample under approximately perpendicular incident condition , this is known as in - plane optical anisotropy
文摘:利用rds测试系统，可以在近垂直入射条件下，测量出样品的反射系数在样品平面内两个互相垂直的方向上的细微差异，即所谓平面内光学各向异性。
The theoretical analysis indicates that the main factors of cover - shelter properties of fabrics are cover factor of fabrics , fabric thicknesss , optical reflectance and absorbance of yarn . with a combination of distances and luminaces , 512 experiments were made to find out the relationship between the least distinguishable distance and reflectance coefficient
通过理论分析,指出了影响织物能见度的主要因素有织物覆盖系数、织物厚度、纱线的光学反射率和吸收率.将测试距离跟织物前与织物后目标物的照度组合成512项实验,由此获得最小分辨距离和反射系数间的关系
