英文摘要	We examine the two-pion interferometry for the expanding sources of spherical quark-gluon plasma evolution. The quark-gluon plasma evolution is described by relativistic hydrodynamics with the equation of state of entropy density. The two-pion Hanbury-Brown-Twiss (HBT) correlation functions are calculated using quantum probability amplitudes in a path-integral formalism. We find the spatial parameter extracted by the two-pion interferometry is sensitive to the phase-space distribution of the pion-emitting source. The expanding velocity of the source leads to a smaller HBT radius and changes the relationship between the HBT radius and the freeze-out temperature.
