脉冲星

Meanwhile, analysis of the acceleration of pulses from a binary pulsar by radio astronomer s at the University of Massachusetts in Amherst in 1978 provided indirect evidence of gravity waves

与此同时，1978年阿默斯特市马萨诸塞大学的射电天文学家们对来自双脉冲星的脉冲的加速度所作的分析，也提供了引力波的间接证据。

Radio pulsars are rapidly spinning neutronstars that emit a lighthouse-like beam of radio waves that sweeps past theEarth as frequently as 600 times per second.

射电脉冲星是一种快速旋转的中子星，它发出的像灯塔的光束一样的无线电波，以每秒500次的速度扫过地球。

In this paper, assuming that pulsar magnetic field is rotating vacuum dipole, which is derived from retarded potential, the PA curve is reinvestigated.

文章采用从推迟势导出的旋转真空磁偶极场，研究了在脉冲星磁场为旋转磁偶极场位形下的线偏振位置角曲线。

Because of the dependence of rotating dipole PA curve on layer of field lines, it avoids the degeneracy problem of conventional rotating vector model that all layers of field lines have the same PA curve with fixed inclination and impact angles, therefore it provides a useful way to identify the emission from different layers and constrain the location of emission regions in pulsar magnetosphere by fitting the observed pulsar radio PA data with rotating dipole PA curve.

其与磁力线层等参数的依赖关系避免了传统旋转矢量模型的简并问题－在给定磁倾角和碰撞角情况下所有层磁力线的偏振位置角曲线都一样，这为通过拟合射电偏振观测数据来分辨不同层的辐射，从而限定脉冲星辐射区部位提供了一条有用的途径。

The cooperation program between China, Australia and Great Britain,"Pulsar timing observation at 18 cm using 25 m radio telescopy of Urumqi", is introduced for its significance, reconstruction of the receiver and its sensitivity.
