Abstract：
Based on the kinetic theory, the distribution function for fermions in quasi-equilibrium QGP, which is perturbed by the fluctuation of the color field, has been obtained. Furthermore, the physical bases that decide the departure factor are analyzed. The characteristics of the departure factor in high-temperature-low-density and low-temperature-high-density are also discussed.
