Query: Universality of the Linear Potential in Effective Models for the Low
  Energy QCD coupled with the Dilaton Field   QCD motivated effective models coupled with the cosmological dilaton field
are analyzed. It is shown that all models possess confining solutions with the
linear potential of confinement even thought such solutions are not observed in
the original effective theory. In case of the Pagels-Tomboulis model analytical
solutions are explicit found.
