Abstract：
The distribution of average transverse-momentum of secondary particles produced in the central region of ultrarelativistic nuclear collisions is studied quantatively with the hydrodynamic model and is compared with JACEE data.The energy density function in SU(3) gauge theory given by Monte-Carlo Calculation is employed to describe the state of the hot matter collision.It is found that the abnormal rapid rise of at high initial energy density region is not from the hydrodynamic motion of quark-gluon plasma.The T> distributions with different initial thermal time and initial radius have been discussed in detail,he main character of distribution does not change with the variation of initial parameters.
