Motion of a thin layer of the Williamson fluid over an inclined 
solid surface in the gravitational field is considered. Expressions 
are obtained for the stationary motion of the film in the gravitation 
field. The influence of the latter and tangential vibrations of the 
solid surface on the flow in the layer is analyzed. It is shown that 
the vibrations generate a pronounced averaged fluid flow even in the 
weak gravitational field in which the film is at rest in the absence 
of vibrations. The effect of the nonmonotonic dependence of the mean 
flow velocity of the film on the vibration frequency of the surface 
is found.
