In this paper, the effects of aberration, retardation and magnetic field sweep back, which are caused by pulsar’s rapid rotation, are estimated to see their influences on the pulse shape of pulsars and geometry asymmetry of the mean pulse profile. The width of mean pulse profile is modified only slightly, but the geometry asymmetry appears and will exhibit different behaviors at different cases. The pulsars of B1451-68 and J0437-4715 are analyzed as examples.
