    "abstract": "We will numerically investgate two-particle correlation function of CERN--SPS\n158 A GeV Pb+Pb central collisions in detail based on a (3+1)-dimensional\nrelativistic hydrodynamical model with first order phase transition. We use the\nYano-Koonin-Podgoretski\\u{\\i} parametrization as well as the usual Cartesian\nparametrization and analyze the pair momentum dependence of HBT radii extracted\nfrom the parametrizations. We find that the interpretation of the temporal\nradius parameters as the time duration in YKP parametrization is not available\nfor the hydrodynamical model where the source became opaque naturally because\nof expansion and surface dominant freeze-out. Finally, effect of the phase\ntransition on the source opacity is also discussed.",
