摘要

从所有已被提出和发现的230多颗超新星遗迹和1300多颗脉冲星中，总结出一个共50对脉冲星与超新星遗迹成协候选体的样本。其中至少20对因为环绕脉冲星的脉冲星风云已被探测到，其成协性应该是真实的。结合近来的观测结果，对导致这种成协对缺失现象的各种因素进行了讨论，尤其深入地讨论了这个样本中有代表性的3个很可能成协的脉冲星与超新星遗迹对。

Abstract

We list a sample of 50 pairs of pulsar (PSR) and supernova remnant (SNR) associations which have been suggested from over 230 SNRs and 1300 PSRs. At least 20 pairs of them are real because the pulsar wind nebulae around the PSRs have been detected. We analyze factors which may result in the deficit of associations. Considering recent observational progress, we simply discuss reality of the 50 pairs cataloged associations and the possibility to detect more PSR/SNR associations. We give a detailed discussion aimed at three pairs of likely PSR/SNR associations PSR J1811-1925/SNR G11.2-0.3, PSR J1932+2020/SNR G55.0+0.3 and PSR J1706/SNR G343.1-2.3 in our sample.
