Abstract：
The relativistic hydrodynamic equations derived from the energy-momentum conservation,are generalized to include the equation of the particle number.The influences of the latent heat and particle distribution on the spectrum are studied on the basis of the generalized formalism.It is shown that these influences should be included,in order to get a reasonable prediction for the formation of the quark matter.
