中文摘要：

（La（1-x）Sr-x）MnO3型热致变色材料是一种新型热致发射率变化功能材料,该材料的最大不足在于对太阳辐射具有很大的吸收率。针对以上问题,本文将一维微结构光谱控制特性应用于（La（1-x）Srx）MnO3型热致变色材料的吸收控制研究,根据太阳辐射能量分布及热致变色材料的应用温度,分析了一维微结构与热致变色材料的匹配特性,确定了一维微结构的光谱特性及其带宽。采用遗传算法优化设计了一维微结构,计算了优化结构的光谱特性,根据其光谱特性分别评估和计算了吸收控制性能和发射率变化特性,并进行了深入分析。

英文摘要：

Spectral control characteristics of one-dimensionaI microstructure is introduced for the investigation of absorption features of a（La（1-x）Srx）MnO3type thermochromatic material. The matching characteristic between the one-dimensional microstructure and the thermochromatic material is analyzed based on the energy distribution of solar radiation and operation temperature of the thermoehromatic material, and the spectroscopic property as welI as the bandwidth of the one-dimensional microstructure is determined. A genetic algorithm optimization design is carried out for the one-dimensional microstructure. The spectroscopic property of the optimal microstructure is calculated, based on which the absorption control performance and the feature of emissivity variation of tile microstructure are calculated.
