摘　　要：本文介绍了溶胶凝胶法制备光谱选择性透过薄膜，通过对样品的光谱透过率的测试，分析和研究这些样品薄膜的性能，结果表明：掺杂碳黑浓度为０．１２％，厚度约为０．３μｍ的二氧化钛薄膜样品的光谱透过性能较优，其在８～１２μｍ波段的透过率超过８０％，在可见光波段内的透过率低于１５％，作为自然辐射冷却应用的选择性透过覆盖材料，它具有阻挡太阳光中可见光加热其下的物体，同时又允许物体的热以辐射方式穿透该薄膜散发到大气外层空间的双重作用。It is introduced in this paper that TiO2 films doped Carbon Black and Zine Sulphide power were prepared by Solgel Process. The spectral transparemcy of these films were studied and analysed. It is found that the selectivity of spectral transparency of the film as a radiative cooling cover is better when the equivalent concentration of Carbon Black power 0.12% and the film thickness is 0.3μm.
