The problem of the flow of rarefied gas through a 
layer of a porous body, which is replaced by a homogeneous system 
of immobile spherical particles, is solved on the basis of the method 
of direct numerical solution of the kinetic Boltzmann equation. The 
effect of the spherical particles on the gas molecules is described 
as a kind of "boundary condition" distributed in space. Dependences 
of the density, temperature, and velocity on the coordinate in physical 
space are obtained; cross sections of the distribution function of 
the gas molecules by velocities are presented.
