花粉是生物气溶胶重要的组成部分，复折射率是研究花粉光学特性以及探测、识别生物气溶胶成分的重要参数。采用压片法对梨花粉2.5～15μm波段的反射光谱进行了测量，利用Krames-Kronig （K-K）关系计算了复折射率，并就傅里叶红外光谱仪测试压片的入射角和复折射率长波长、短波长区外推两方面对结果作了误差分析。结果表明，测试时18°入射角以及长波长、短波长区外推对梨花粉复折射率的计算结果影响不大，利用反射光谱计算花粉复折射率的方法是可行的。计算得到的复折射率谱对梨花粉光学特性的研究以及生物气溶胶成分的探测、识别有一定的参考价值。

Pollen is an important part of bioaerosols ,and its complex refractive index is a crucial parameter for study on optical characteristics and detection ,identification of bioaer-osols .The reflection spectra of pear pollen within the 2 .5~15μm wave-band were measured by squash method .Based on the measured data ,the complex refractive index of pear pollen within the wave-band of 2 .5 to 15 μm was calculated by using Kramers-Kroning (K-K) rela-tion ,and calculation deviation about incident angle and different reflectivities at high and low frequencies were analyzed .The results indicate that18 degrees angle of incidence and different reflectivities at high and low frequencies have little effect on the results ,and it is practicable to calculate the complex re-fractive index of pollen based on its reflection spectral data .The data of complex refractive index of pollen have some reference value for optical characteristics of pollen ,detection and identification of bioaerosols .
