Effects of multi-pion correlations on the source distribution in   ultra-relativustic heavy-ion collisions
  Multi-pion correlation effect on the source distribution is studied. It is shown that multi-pion Bose-Einstein correlation make the average radius of the pion source become smaller. The isospin effect on the pion multiplicity distribution and the source distribution is also discussed.
