Abstract：
From QGP kinetic equations with collision integrals,by using the realaxation time approximation,we calculate the distribution functions to the second order correction. We obtain the distribution functions for quarks (and anti-quarks) and gluons under the perturbation of the fluctuation of the color field.Then in the high-temperature-low-density area,we discuss the characteristics of the distribution functions,and use them to get the net baryon density and the energy density.
