DESCRIPTION:Scalar fields play an important role in cosmology and have att
 racted a great deal of recent research interests. Their impact on the larg
 e scale structure formation\, especially in models with a dark-matter-scal
 ar-field coupling\, has been studied thoroughly in the linear regime. Howe
 ver\, little is known about its behaviour in the nonlinear regime of struc
 ture formation and in the literature its effect is often approximated to b
 e a Yukawa-type fifth force or a rescaling of gravitational constant. Here
  we report some recent pregress in this area\, in which we solve the spati
 al configuration in a consistent manner\, without resorting to the above a
 pproximations. This provides a new and quantitatively more accurate way fo
 r the studies in scalar field cosmology.
