Analytical solution of a one-dimensional hydrodynamical model is derived, where phase transition from the quark-gluon plasma state to the hadronic state is effectively taken into account. The single-particle rapidity distribution of charged $\ensuremath{\pi}$ mesons observed in relativistic heavy ion collisions is analyzed by the model. Space-time development of the fluid is also investigated.
