论文摘要
脉冲星在偏移范围内超过0.4秒的脉冲星-9O <decJ <42o，在右升峰范围内，0H <r.a. <24H <24H <24H与行星际闪烁程序并行搜索，该程序通过radiotelescope lpa lpi lpi lpi的频道闪烁程序监测了大量源。在带2.5 MHz的中央频率110.25 MHz和六个频率通道中进行的四年观察结果使用时间分辨率100 ms进行搜索。脉冲星的候选者的初始检测是基于整个观测期间平均的傅立叶功率谱。从观测分析中检查了脉冲星的候选物，并以较高的时间频率分辨率进行检查：32个频道，时间分辨率为12.5 ms。发现了18个新的脉冲星，并提出了其主要特征。
Pulsars with periods more than 0.4 seconds in the declination range -9o < decj < 42o and in the right ascension range 0h < r.a.< 24h were searched in parallel with the program of interplanetary scintillations monitoring of a large number of sources with the radiotelescope LPA LPI. Four-year observations carried out at the central frequency 110.25 MHz in the band 2.5 MHz and in six frequency channels with the time resolution 100 ms were used for the search. Initial detections of candidates for pulsars were based on the Fourier power spectra averaged over the whole observations period. The candidates for pulsars were checked in more details from observations analysis with higher time-frequency resolution: 32 frequency channels with time resolution of 12.5 ms. 18 new pulsars was discovered, their main characteristics are presented.
