摘要：

We utilized the AMPT model to simulate the shear viscous transport dynamics of parton matter with varying specific shear viscosity and phase- transition temperatures and investigate the effect on the HBT radii of charged pions at the root sNN = 200 GeV Au+Au collisions. The emission- source size is sensitive to the shear viscosity of parton matter, thus, increasing the shear viscosity to entropy density ratio will reduce the HBT radii. The phase-transition temperature can regulate the evolution duration of the parton and hadron phases. Raising the phase-transition temperature shortens the evolution time of the partonic phase and extends the evolution time of the hadronic phase, resulting in an increase in the total system evolution time. A prolonged hadronic-phase evolution weakens the dependence of the transverse HBT radii on transverse mass and increases the evolution time scale.
