论文摘要
在2000年至2014年之间，Nanshan 26-M 26-M射电望远镜的定时观察已用于寻找故障。九个脉冲星的数据跨度为11.6至14。2年。从总计114年的脉冲星旋转历史记录中，在9个脉冲星中发现了16个新的故障。通过拟合定时残差数据来测量故障参数。所有16个故障的尺寸都很小。在PSR J1833-0827中检测到了六个新的故障，使其成为另一个经常出现的小故障。 16个故障中的某些可能会经历指数性或线性恢复，但是对于我们的数据集中的较大差距，我们不太可能进行进一步的分析。从Nanshan获得的所有故障率都高于Jodrell Bank天文台。小故障尺寸和高小故障率可能归因于高观察节奏。
Timing observations from the Nanshan 26-m radio telescope for nine pulsars between 2000 and 2014 have been used to search for glitches. The data span for nine pulsars ranges from 11.6 to 14.2 years. From the total of 114 yr of pulsar rotational history, 16 new glitches were identified in 9 pulsars. Glitch parameters were measured by fitting the timing residuals data. All 16 glitches have a small fractional size. Six new glitches have been detected in PSR J1833-0827, making it another frequent glitching pulsar. Some of the 16 glitches may experience exponential or linear recovery, but it is unlikely for us to make further analyses with the large gap in the data set. All the glitch rates obtained from Nanshan are higher than that from Jodrell Bank Observatory. The small glitch size and high glitch rate could possibly attribute to the high observation cadence.
