We study the properties of the pulsed component of hard (>2keV) X-ray emission from pulsars based on the new version of the outer-gap model proposed by Zhang et al. (2004ApJ...604..317Z). In this outer-gap model, high-energy photons emitted by relativistic charged particles produce e^± pairs through magnetic-pair production on their way from the outer gap to the neutron-star surface, and these pairs produce the bulk of pulsed X-rays by the synchrotron radiation. The X-ray luminosity of rotation-powered pulsars is a function not only of the period and magnetic field strength, but also of the magnetic inclination angle. Application of this model to the observed pulsed X-ray emission of normal pulsars by ASCA shows a better consistence. Further, the inclination angles of these pulsars are estimated using the observed X-ray data, and the predicted conversion efficiencies of high-energy γ-rays for seven confirmed γ-ray pulsars are consistent with the observed data.
