| 摘 要： | 统计分析了目前发现的几种脉冲星的自转周期和表面磁场以及空间的分布情况,揭示出毫秒脉冲星比普通射电脉冲星、LMXB(低质量X射线双星)比HMXB(高质量X射线双星)的空间分布要更加弥散；孤立毫秒脉冲星自转周期分布的峰值为4.7 ms,而普通脉冲星的相应值为0.6 s,双星中毫秒脉冲星这一值为3.5 ms; FERMI脉冲...

| Abstract: | The period distribution and surface magnetic field strength distribution of pulsars as well as the spatial distribution of pulsars are analyzed statistically.The spatial distribution of millisecond pulsars is more dispersive than that of normal radio pulsars.And the spatial distribution of low-mass X-ray binary pulsars is also more dispersive than that of high-mass X-ray binary pulsars.The peak values of the rotation period distributions of isolated millisecond pulsars,normal radio pulsars and millisecond p... |
