中文摘要：

脉冲星自1967年发现以来,50年的观测和理论研究取得巨大进展,期间曾2次获颁诺贝尔物理学奖。脉冲星以其高度致密和强引力场堪称宇宙天然实验室,可用来验证爱因斯坦广义相对论及进行引力波探测,推动了天文学与物理学研究的发展。本文简介了脉冲星的发现及其性质,并综述了脉冲星导航以及最近建成的500 m口径球面射电望远镜（FAST）的脉冲星探测研究进展。

英文摘要：

The observation and the theoretical study of the pulsar have made a great progress since the first pulsar was discovered in 1967, honored with two Nobel Prizes. It is an extremely large physical laboratory in the universe, which not only can test the general relativity, but also measure the predicted gravitational waves. In this paper, we review the history and the properties of pulsars, and analyze its applications in the gravitational wave detection and the pulsar navigation. The pulsar detection of the five-hundred-meter Aperture Spherical Radio Telescope （FAST） is discussed, at the end.
