摘　　要：The global structure of current flows in pulsar magnetosphere is investigated, with rough calculations of the circuit elements. It is emphasized that the potential of the critical field lines （the field lines that intersect the null surface at the light cylinder radius） should be the same as that of interstellar medium, and that pulsars whose rotation axes and magnetic dipole axes are parallel should be positively charged, in order to close the pulsar＇s current flows. The statistical relation between the radio luminosity and pulsar＇s electric charge （or the spindown power） may hint that the millisecond pulsars could be low-mass bare strange stars.The global structure of current flows in pulsar magnetosphere is investigated, with rough calculations of the circuit elements.
