Analysis about formation of multi peak spectrum in Mie scattering of small particles

According to the analysis of the measurement error of particle size analyzer,we found that the main reas on of mistake judgement was multi-peak scattering spectrum.Several factors could produce the multi-peak scattering spectrum,such as optical unsymmetry of particles,shape of the particles,beam profile un-uniformity.This paper proposed a inte grating judgement method to avoid the mistake judgement.
