摘要：
The propagation of plane, spherical, and cylindrical waves in multifractional gas suspensions with polydisperse inclusions has been studied. The fractions differ in inclusion size and inclusion-size distribution functions, and also in material. A dispersion relation and equilibrium and frozen velocities of sound have been obtained. Dependences of the damping decrement at the wavelength on the dimensionless perturbation frequency have been constructed. The influence of heat transfer on the dampings of the waves has been shown.
