摘　　要：微生物气溶胶作为大气气溶胶的重要组成部分,可以通过吸收或散射影响大气辐射特性。当前对于微生物气溶胶光学特性的研究,多局限于单波段或单种质,无法归纳出微生物气溶胶光学特性的一般性和特殊性,不利于全面分析微生物气溶胶对大气辐射特性的影响。测量了三种真核孢子微生物和三种原核杆菌微生物材料在0.25~15μm波段的光谱反射率,结合K-K算法计算复折射率m,并对微生物FTIR光谱进行分析,比较了真核与原核微生物0.25~15μm波段光学特性的相同与相异之处。研究结果可以帮助全面理解和定量计算大气辐射特性,为微生物气溶胶遥感探测和类型鉴别提供理论支撑,为开发新型功能性材料提供了新思路。Microbial aerosols, as an important component of atmospheric aerosols, can affect atmospheric radiation characteristics through absorption or scattering. At present, the research on the optical properties of microbial aerosols is mostly limited to single-band or single germplasm. It is impossible to generalize the generality and particularity of microscopic aerosol optical properties, which is not conducive to comprehensively analyze the effects of microbial aerosols on atmospheric radiation characteristics. Herein,the spectral reflectances of three eukaryotic microbe and three prokaryotic microbes in the waveband from 0.25 to 15 μm were measured. Based on the Kramers-Kroning algorithm, the complex refractive index(CRI) m was calculated and the FTIR spectra of microbes were analysed. The similarities and differences between the optical properties of the 0.25-15 μm band of eukaryotic and prokaryotic microorganisms were compared. The conclusion can help to comprehensively understand and quantitatively calculate atmospheric radiation characteristics, provide theoretical support for microbial aerosol remote sensing detection and type identification, and provide new ideas for the development of new functional materials.
