玻璃表面反射玻璃具有反射光的本领。太阳光通过空气垂直入射到玻璃表面时,玻璃表面的反射率R可以用下式计算: R(n_g-1/n_g+2)~2式中n_g是玻璃的折射率。平板玻璃的折射率一般为1.52,即n_g=1.52,代入上式即可算出它的反射率(约为4.3％),如果同时考虑 Glass Surface Reflective Glass has the ability to reflect light. When the sunlight is incident perpendicularly to the glass surface through the air, the reflectance R of the glass surface can be calculated as follows: R (n_g-1 / n_g + 2) ~ 2 where n_g is the refractive index of the glass. Flat glass refractive index is generally 1.52, that n_g = 1.52, into the above formula can be calculated its reflectivity (about 4.3%), if both
