  In present article effective nonlinear sigma model (NSM) is considered.
  Einstein equation solution, corresponded to the chiral fields determined by
functional parameter method, are presented.
  Effective NSM of stationary axially-symmetric gravitational field is
constructed. Motion equations are solved exactly by functional parameter
method. Einstein equations solution are constructed.
  For particular dependences of functional parameter graphics of solutions are
presented. Metric coefficients behaviour is shown to be similar as functional
parameter one.
