摘要：

The Five-hundred-meter Aperture Spherical radio Telescope （FAST） is the most sensitive telescope at the L-band（1.0–1.5 GHz） and has been used to carry out the FAST Galactic Plane Pulsar Snapshot （GPPS） survey in the las5 yr.Up to now,the survey has covered one-fourth of the planned areas within±10~ofrom the Galactic plane visible by FAST,and discovered 751 pulsars.After the first publication of the discovery of 201 pulsars and one rotating radio transient （RRAT） in 2021 and 76 RRATs in 2023,here we report the discovery of 473 new pulsars from the FAST GPPS survey,including 137 new millisecond pulsars and 30 new RRATs.We find 34 millisecond pulsars discovered by the GPPS survey which can be timed with a precision better than 3μs by using FAST15 minute observations and can be used for pulsar timing arrays.The GPPS survey has discovered eight pulsars with periods greater than 10 s including one with 29.77 s.The integrated profiles of pulsars and individual pulses of RRATs are presented.During the FAST GPPS survey,we also detected previously known pulsars and updated parameters for 52 pulsars.In addition,we discovered two fast radio bursts plus one probable case with high dispersion measures indicating their extragalactic origin.
