The effect of distributions of nonuniformities in the diameter, heat capacity, and material density of small spherical particles on the properties of a dust-gas suspension passing through a normal stationary shock wave is studied numerically. It was found that the gas temperature is practically independent of the size distribution of the dust particles. The suspension pressure, however, is very sensitive to the size distribution. It rises very sharply when the suspension contains mainly small particles. A distribution in the specific heat capacity of the solid particles results in a minor effect on the velocities and the pressure and in a pronounced effect on the temperature of the solid particles. A distribution in the material density of the solid particles affects both the velocities and the temperatures of the solid and gaseous phases.
