Pulsar polarization profiles are very basic database for understanding theemission processes in pulsar magnetosphere. After careful polarizationcalibration of the 19-beam L-band receiver and verification of beam-offsetobservation results, we obtain polarization profiles of 682 pulsars fromobservations by the Five-hundred-meter Aperture Spherical radio Telescope(FAST) during the survey tests for the Galactic Plan Pulsar Snapshot (GPPS)survey and other normal FAST projects. Among them, polarization profiles ofabout 460 pulsars are observed for the first time. The profiles exhibit diversefeatures. Some pulsars have a polarization position angle curve with a goodS-shaped swing, and some with orthogonal modes; some have components withhighly linearly components or strong circularly polarized components; some havea very wide profile, coming from an aligned rotator, and some have aninterpulse from a perpendicular rotator; some wide profiles are caused byinterstellar scattering. We derive geometry parameters for 190 pulsars from theS-shaped position angle curves or with orthogonal modes. We find that thelinear and circular polarization or the widths of pulse profiles have variousfrequency dependencies. Pulsars with large fraction of linear polarization aremore likely to have a large Edot.
