【摘要】 射电脉冲星周期跃变被认为是研究中子星内部结构和状态的极好探针．脉冲星高频巡天发现了一批年青脉冲星，脉冲星周期跃变的观测研究也有了飞快进展。至少发现了２５颗有跃变现象的脉冲星（简称跃变脉冲星）和 ７６次跃变事件。 ＰＳＲ Ｊ０８３５—４５１０是目前已有跃变脉冲星中跃变活动参数最高的， ＰＳＲ Ｊ１３４１—６２２０的跃变活动最频繁，而 ＰＳＲ Ｊ１６１４—５０４７在１９９５年发生的跃变是规模最大的。不同脉冲星的跃变事件的恢复过程很不相同。更多还原

【Abstract】 The glitch of radio pulsars is excellent probe for investigating the interior structure and state of neutron stars. A much larger sample of young pulsars were discovered with relatively high-freguency surveys and at least 76 glitches are found in 25 pulsars. Among them PSR J08354510 suffers many giant glitches. 12 glitches in PSR J1341--6220 make it the most frequently glitching pulsar known so far. The largest known glitch in PSR J1614--5047 occured in 1995. The post--glitch relaxation varies from pulsar to pulsar.更多还原
