摘要
本文应用Mie理论,计算了磷烟在7.6～12.8μm波段各波长下的消光因子Q_(ex)、散射效率因子Q_(sc)和吸收效率因子Q_(ab),并用遥光源傅里叶变换红外光谱法测量了磷烟在相应波段的消光光谱。研究结果表明,磷烟对远红外辐射具有一定的遮蔽效果,理论计算与实验测量结果具有较好的一致性。
Based on Mie theory, the extinction efficiency factor Q_(ex), scattering efficiency factor Q_(sc) and absorption efficiency factor Q_(db) of phosphorus-derived smoke are calculated at individual wavelength from 7.6 to 12.8 μm. The extinction spectra of phosphorus-derived smoke in the same region are measured by remote source Fourier transform infrared spectroscopy. The experimental results show that the phosphorus-derived smoke has certain obscuring effects in the Far-infrared region. The results are consistent with the values calculated by using Mie theory.
