摘要：
The kinetic freeze-out process of a pion gas through a finite layer with time-like normal is considered. The pion gas is described by a Boltzmann gas with elastic collisions among the pions. Within this model, the impact of the in-medium pion mass modification on the freeze-out process is studied. A marginal change of the freeze-out variables temperature and flow velocity and an insignificant modification of the frozen-out particle distribution function has been found.
