摘 要
|
乌鲁木齐天文站自1999年以来陆续研制完成脉冲星1.5GHz频段消色散接收系统,0.327GHz,0.61GHz,2.3GHz, 4.8GHz和8.4GHz等5个频段上的单通道的脉冲星接收系统和2组双频(2.3GHz和8.4GHz及0.327GHz和0.61GHz)同时观测的接收系统。上述设备均已投入观测，并取得一批诸如脉冲星周期参数、周期跃变、自行速度、脉冲轮廓模式变化、星际闪烁和谱特性等观测成果。

Abstract
|
The 1.5GHz de-dispersion pulsar-timing observation system of UAO has
been made since 1999. We also built the single-channel receivers at
0.327GHz, 0.61GHz, 2.3GHz, 4.8GHz and 8.4GHz. And then the
simultaneous de-dispersion observation system at 2.3GHz and 8.4GHz and
the simultaneous single-channel observation
system at 0.327GHz and 0.61GHz were successfully developed. Some
scientific results such as glitch, model changing, inter-stellar
scintillation and the spectra of pulsar, have been obtained by using
these equipments. |
