Comoving cooling rates of different cooling mechanisms for the electrons with the energy distribution in calculation PJR15Γ1000. The cooling rates at two epochs (0.001 s, red; 0.006 s, blue) are shown, and the SSC, synchrotron, and adiabatic cooling mechanisms are illustrated as the solid, dashed, and dotted lines, respectively. In this case, the cooling of electrons with ﹩{\gamma }_{{\rm{e}}}^{{\prime} }\gt {10}^{2}﹩ is dominated by synchrotron radiation, whereas electrons with ﹩{\gamma }_{{\rm{e}}}^{{\prime} }\lt {10}^{2}﹩ are mainly cooled by adiabatic cooling.
