摘要：
The search for pulsars in monitoring data obtained at the radio telescope Large Phased Array (LPA) at a frequency of 111 MHz was carried out. Daily round-the-clock observations were carried out for about 3000 d. The duration of the observation session for each direction in the sky was 3.5 min d(-1). The search for pulsars was carried out using power spectra. To search for weak pulsars, power spectra were summed up. The expected increase in sensitivity was 35-40 times compared to observations in one session. In a blind search, 330 pulsars with regular radiation were detected, with periods (P) from 0.0333 to 3.7455 s and dispersion measures (DMs) up to 249 pc cm(-3). 39 pulsars turned out to be new. Average profiles were obtained for six pulsars. The DMs for seven pulsars previously detected on the LPA have been clarified.
