从材料的光学性能（透过率）与传热性能（导热系数）两个方面，对各种窗用材料节能的机理进行理论分析与实验测试．结果表明，窗用材料的选择及使用方法，对节能效果影响明显．这为节能建筑光窗材料的设计与应用提供了依据．
From the aspects of optical properties (transmittance) and heat transfer performance (thermal conductivity) of materials, theoretical analysis and experimental testing of the energy saving mechanisms of various window materials are performed. The results show that the selection and use of window materials have a significant effect on energy saving. This provides the basis for the design and application of energy-saving light window materials.
