| Abstract: | The phase structure of hadrons and the quark-gluon plasma is investigated by two types of equation of state of the hadrons,
namely the ideal hadron gas model and the compressible bag model. It is pointed out that, while the ideal gas model produces
an unrealistic extra hadron phase, the compressible bag model gives the expected and reasonable phase diagram even if the
rich hadron spectrum is taken into account.
