With excellent lightreflectance and weather resistance, have to save energy, which makes protective layer can be.
具有优良的光线反射能力和耐候性，有利于建筑节能，其上可不做保护层。

Due to their poor chemical durability, it is proposed to coat a layer of organosilicon (with 97% visual lightreflectance) on the glass surface which will dramatically improve their chemical duration.
这类玻璃的化学稳定性较差，当表面涂以可见光反射率为97%的有机硅层后，稳定性显著提高。

The expression of Fresnel formula, the reflectance of light intensity, and the transmission of light intensity were given in this particular case.
