Paper Abstract

General parameters of polydispersive suspensions of homogeneous aspherical particles of different orientation structure have been found, and their integral optical characteristics are accorded with such characteristics of sphere in general coordinates. On the basis of exact theory new optical effects absent in conclusions of known approximation have been found, particularly appearance of unreal polydispersive function. It has been proved that in first approximation the coefficient of spectrum absorption (scattering) transformation of suspension is invariable. On this basis the method of determination of spectrum indices of absorption and scattering of matter of `soft' dispersive particles has been proposed. Analytical expression for integral light scattering phase function has been obtained. Using this expression in approximation of RGD (Rayleigh-Gans-Debye) approach, express-method and apparatus for the estimate of average sizes of suspension particles are worked out.
