Abstract：
Based upon the relativistic bydrodynatnics, it is pointed out that although the recent data on the first single-photon spectrum show a linearity, it does not mean that in an ultra-relativistic auclei-auclei collision the system reaches equilibrium at some temperature in whole, making use of a new dynamical mechanism for hadronztion. phase transition, the evaluating results predict that if the phase transition from QGP to badronic matter is of first-order, for higher colliding energies (e.g.>200GeV/u) the photon spectra would show some concave curvature, which may be a possible signature for diagaosiog QGP.
