摘      要:In this study,we consider an open system from the thermodynamic perspective for an adiabatic FRW universe model in which particle creation occurs within the *** this case,the modified continuity equation is obtained,and then,we make it correspond to the continuity equation of f(T)***,we take f(T)gravity with a viscous fluid in the flat-FRW metric,where T is the torsion *** assume the contents of the universe to be dark matter and dark energy and consider an interaction term between *** interesting point of this study is that we make the modified continuity equation resulting from particle creation equivalent to the matter continuity equation resulting from f(T)*** result of this evaluation establishes a relationship between the number of particles and scale *** what follows,we write the corresponding cosmological parameters in terms of the number of particles and also reconstruct the number of particles in terms of the redshift *** then parameterize the Hubble parameter derived from power-law cosmology with 51 data points from the Hubble observational parameter ***,we plot the corresponding cosmological parameters for dark energy in terms of the redshift to investigate the accelerated expansion of the *** addition,by using the sound speed parameter,we discuss the stability and instability analyses of the present model in different eras of the ***,we plot the density parameter values for dark energy and dark matter in terms of the redshift parameter.
