Abstract：
The evolution of strangeness in an expanding quark-gluon plasma formed by ultrarelativistic nucleus-nucleus collisions was studied by solving relaxation equations.In the calculation,the 3-dimensional expansion effect of the system was described by relativistic hydrodynamic equations.The temperature effect of the latent heat released by the phase transition on the evolution of strangeness was considered.
