英文摘要	We investigate the possibility that pulsars act as the lens in gravitational microlensing events towards the Galactic bulge or a spiral arm. Our estimation is based on the anticipated survey and observations of the Five hundred metre Aperture Spherical Telescope (FAST) and the Square Kilometer Array (SKA). Two different models of pulsar distribution are used. We find that the lensing rate is >= 1 event per decade, which is high enough to search for the real events. Therefore, microlensing observations that will focus on pulsars identified by FAST or SKA in the future are important. As an independent determination of pulsar mass, the future detection of microlensing pulsars should be significant in the history of studying pulsars, especially in constraining the state of matter (either hadronic or quark matter) at supra-nuclear densities. Observations of such events in the future using advanced optical facilities (e.g. the James Webb Space Telescope and the Thirty Meter Telescope) are highly recommended.
