The non-equilibrium dynamic transition of an Ising spin system driven by an oscillating field was studied through solving the mean-field equation of motion based on Glauber dynamics. By approaching the temperature t and the amplitude h(0) of the driving field to their critical values t(C) and h(0c) simultaneously, we worked out a scaling formula that relates the reduced dynamic order parameter Q/Q(max) of the system with both critical temperature t(c) and critical amplitude h(0c) i.e. Q / Q(max) similar to (h(0c) - h(0))(
