By considering synchrotron radiative process in the internal shock model andassuming that all internal shocks are nearly equally energetic, we analyze thegamma-ray burst (GRB) emission at different radii corresponding to differentobserved times. We apply this model to GRB 050904 and find that our analyticalresults can provide a natural explanation for the multi-band observations ofGRB 050904. This suggests that the X-ray flare emission and the opticalemission of this burst could have originated from internal shocks being due tocollisions among nearly-equally-energetic shells ejected from the centralengine. Thus GRB 050904 appears to be a burst with super-long central engineactivity.Comment: 16 pages, 4 figure. Submitted on Oct. 21, 2005, accepted by Ap
