solar reflectivity

To improve efficiency of the solar heat collector, a wide band antireflective ( AR) coating composed of nanostructure porous SiO 2 particles was designed and coated on the transparent glazing of a solar collector to reduce its reflectivity.

为了提高太阳集热器的集热效率，必须抑制透明盖板表面的反射，纳米多孔SiO2薄膜可以达到宽带减反射效果。

The infrared reflectivity of green solar reflective coat, a widely used material, and the factors that affect the infrared reflectivity were studied.

研究了具有重要实用价值的绿色太阳光谱反射涂层的近红外反射率，探讨了影响涂层反射性能的因素。

The reflectivity of land to solar radiation is much higher than that of ocean.

陆地对太阳辐射的反射率远远高于海洋.

By means of surface morphology observation, reflectivity measurement, surface temperature observation, we analysis and interpretation the mechanism of enhanced solar thermoelectric generator power.

借助表面形貌观测、反射率测量、表面温度观测等方式对表面微纳结构增强太阳能温差发电器发电功率机理进行了分析和解释。

The results showed that: the reflectivity of the forest was related to solar altitude. It was generally high just after sunrise or before sunset, but was relatively stable as solar altitude was higher than 30 °. The diurnal curves of reflectivity took U shape.

结果表明，森林的反射率与太阳高度角有关，在太阳高度角很小的日出和日落附近反射率较高，太阳高度角大于30°时反射率变化不大，反射率的日变化曲线为U形。
