采用压片法对黑曲霉孢子2.5~15μm波段的反射光谱进行了测量。针对采集的光谱数据，利用Krames-Kronig(K-K)关系对黑曲霉孢子2.5~15μm波段的复折射率进行了计算。然后,根据Mie散射理论求出了2.5~15μm波段黑曲霉孢子质量消光系数，并对结果进行了分析和讨论。分析结果表明，在粒径r=1.2μm时，黑曲霉孢子在2.5~15μm波段的平均质量消光系数为0.68 m2/g，随着粒径的增大，平均质量消光系数单调减小；与常见无机物相比，黑曲霉孢子在2.5~15μm波段具有较好的消光性能，而且在保证一定消光性能的情况下，黑曲霉孢子的粒径尺寸要求相对较宽。

The reflection spectra of Aspergillus niger spores within the waveband of 2.5-15 μm were measured by squash method. Based on the measured data, complex refractive index of Aspergillus niger spores within the waveband of 2.5-15μm were calculated by using Krames-Kronig (K-K) relationship. Then, the mass extinction coefficient of Aspergillus niger spores within the waveband of 2.5-15μm were obtained by utilizing Mie scattering theory, and the results were analyzed and discussed. The average mass extinction coefficient of Aspergillus niger spores is 0.68 m2/g in the range of 2.5-15μm, and the average mass extinction coefficient decreases monotonically with the particle size increases. Compared with common inorganic compounds, Aspergillus niger spores possesses a good extinction performance within the waveband of 2.5-15 μm, and the requirement of particle size is relative wide in a certain extinction performance.
