| 摘 要： | 黑曲霉孢子是生物气溶胶的重要组成部分,质量消光系数是研究黑曲霉孢子电磁衰减特性的重要参数。采用压片法测量了灭活前后黑曲霉孢子2.5~15 um 波段的反射光谱,并利用Krames-Kronig(K-K)关系计算了黑曲霉孢子红外波段的复折射率。基于Mie 散射理论求出了灭活前后黑曲霉孢子红外波段的质量消光系数,并对结果进行了分析和讨论。分析结果表明:3~5 um 波段,灭活后平均质量消光系数降低了4.6%,8~14 um 波段,灭活后平均质量消光系数降低了89.5%,由此可知,保持活性对于提高黑曲霉孢子的电磁衰减能力具有重要的意义。

| Abstract: | Aspergillus niger spores is an important part of bio-aerosols, and its mass extinction coefficient is an important parameter for study on electromagnetic attenuation characteristics of aspergillus niger spores. The reflection spectra before and after aspergillus niger spores inactivation within the 2.5-15 um waveband were measured by squash method. The complex refractive index of aspergillus niger spores in the infrared waveband was calculated by using Kramers-Kroning (K-K) relation. Then, based on Mie scattering theory, the mass extinction coefficient before and after aspergillus niger spores inactivation in the infrared waveband were obtained, and the results were analyzed and discussed. The results show that average mass extinction coefficient has a decrease of 4.6 percent in the 3-5 um waveband and a decrease of 89.5 percent in the 8-14 um waveband. In light of this, to retain activity of aspergillus niger spores will play an important role in the increasing of its electromagnetic attenuation abilities. |
