粉体材料的法向光谱发射比测试系统的设计

阐述了采用“单光束比较辐射度量法”测量材料的法向光谱发射率的原理和系统设计 方法;改进、设计制作了黑体炉、样品炉、斩波装置、扫描装置和A/ D 转换系统,用V C + + 完成了“法向光谱发射比测试系统中文操作软件”的编写;利用此系统测量了涂料样品的法向光谱发射率。

Design of a Measure System for Normal Spectral Emittance of Powder Materials

The principles and the system designing method of measuring the normal spectral emittance of materials with the method of single beam comparative radiation are introduced. The black radiation ,the sample radiation ,the chopper equipment ,the scanning equipment and A/ D conversion system are improved. The Chinese operation software of the Normal spectral emissivity testing system with the VC+ + have also completed. The equipment is adopted to measure the normal spectral emittance of painting samples.
