文摘The complex refractive index of small ash particles is determined from the transmittance spectrum of dilute particle suspensions obtained from experiment and by the application of the precise Mie scattering theory and dielectric dispersion Kramers-Kroning relations. The numerical simulation results for the ash particles with data given in literature [1] show that with this method the accuracy is improved and the applicable range of the wavelength and the particle size is expanded.At last the transmittance spectrum of the ash particle cloud from Tic Fa Coal Mine was measured by an infrared spectrometer and its complex refractive index is determined.
