| 英文摘要 | In this paper, we study 11 pulsars that were discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in the Commensal Radio Astronomy FAST Survey. We report their phase-connected timing ephemeris, polarization pulse profiles, and Faraday rotation measures. The timing analysis shows that our sample includes seven normal pulsars and four (PSRs J0245+3219, J1437+3049, J1759-1248, and J1813-0852) millisecond pulsars, with periods ranging from 3.15 ms to 2.54 s, characteristic ages from 5.48 x 105 to 1.06 x 1010 yr, and surface magnetic fields from 1.46 x 108 to 1.18 x 1013 G. Six normal pulsars exhibit rich radiation characteristics, including nulling and subpulse drifting. PSR J0245+3219 (30.93 ms) has a spin period, characteristic age, surface magnetic field, and galactic height that are consistent with the parameters of disrupted recycled pulsars. PSR J1813-0852 (4.23 ms) is in a binary system with an orbit of 83.47 days, an eccentricity of 2.9 x 10-4, and its companion has a mass ranging from 0.28 to 0.76 M circle dot. PSR J1813-0852 exhibits a spin period, companion mass, and orbital eccentricity that align well with the predicted characteristics of a millisecond pulsar-helium white dwarf systems. |
