The image jets modeling of gravitationally lensed sources
  The jets image modelling of gravitationally lensed sources have been
performed. Several basic models of the lens mass distribution were considered,
in particular, a singular isothermal ellipsoid, an isothermal ellipsoid with
the core, different multi-components models with the galactic disk, halo and
bulge. The obtained jet images were compared as with each other as with results
of observations. A significant dependence of the Hubble constant on the model
parameters was revealed for B0218+357, when the circular structure was took
into account.
