摘　　要：A technique is preseoted that the complex refractive indices of particles are deduced from the measured transmittance spectrum of a dilute mono-dispersion by use of the Mie theory and the K-K relation. The complex refractive indices of slag can also be obtained from the transmittance spectrum of slag combined with nesnel reflection law and K-K relation. The experiment and calculation of ash particles and slag have been made, the results showthe differellt properties between bulk and particles.A technique is preseoted that the complex refractive indices of particles are deduced from the measured transmittance spectrum of a dilute mono-dispersion by use of the Mie theory and the K-K relation.
