Although pulsars can radiate electromagnetic wave from radio to gamma ray
bands, we still have no a united model to understand the multi-band emission.
In this paper the effort for a joint model is presented. The inverse Compton
scattering (ICS) and a second acceleration process near the null charge surface
are involved to account for the radio and the gama-ray emission, respectively.
Various kind of pulse profiles and other observational properties can be
reproduced.Comment: 5 pages, 2 figure, IAU Symposium No.214 on "High Energy Processes and
