摘　　要：本文利用ＣＯＳ－Ｂ卫星观测资料对ＣＧＲＯ卫星新近发现的一颗γ射线脉冲星进行了守时性分析，得到了显著的周期结构。这个结果对ＰＳＲ１０５５－５２是一颗γ射线脉冲星提供了新的、独立的证认，本文对普遍公认的六颗γ射线脉冲星也作了比较和讨论。Using the COS-B data, we analysed the timing parameters of the γ-ray pulsar PSR1055-52 newly discovered by Compton GRO and found the significant pulsed phase structure quite similar to that found by CGRO. This result provides an independent support for the PSR1055-52 to be a γ-ray pulsar. This γ-ray pulsar is also compared with other 5 widely known ones.
