摘　　要：采用传统的节能减排的方法来控制地球温室效应需要在全世界范围内进行协调,这是一项十分艰难的工作,若能采用反射板等将太阳能量向太空反射,则是人类采用技术手段来主动控制温室效应,执行起来要容易、可行得多。本文以美国杜邦油漆为例,研究了在金属基底上喷涂白漆涂层对太阳能量的光谱反射率,研究显示,杜邦白漆涂层在太阳辐射的峰值波段具有很大的反射率,达到了90%以上,在未考虑大气作用的情况下,白油漆对太阳能量的平均反射率达到了71.6%,杜邦其它颜色漆的反射率均没有白油漆大。To control the green house effect of the earth with the traditional energy-saving and emission-reduction method needs to harmonize in the global world range,and this is very hard work.If the solar energy is reflected to the outer space by reflecting plate made by human,it＇s the technology method that human control the earth green house effect on human＇s own initiative and is carried out more easily.Taking the American DuPont paint as an example,the spectral reflectivity to the solar energy of the white paint on metal plate is studied in the paper.Our study shows that,DuPont white paint has very big reflectivity in the wave length of the solar radiative energy of peak value,and reaches more than 90%.Ignoring the influence of the atmosphere to the solar radiative energy,the average reflectivity of the white paint to the solar radiative energy reaches 71.6%,and the reflectivity of the other DuPont paint is less than that of the DuPont white paint.
