摘　　要：太阳黑子是太阳活动的重要外在特征,且与诸多太阳活动指标有良好的相关性.黑子数据在太阳活动、空间环境、日地关系及地球气候变化等方面均有广泛应用.国际太阳黑子相对数是各类黑子数据中观测时间最长的时间序列,在诸多研究中均有十分重要的作用.2015年,国际太阳黑子相对数经过校订,公布了新版本.新、旧版本的数据存在诸多差别,而这些差别可能会对使用该数据开展的研究以及研究方法造成一定的影响.本文对新、旧版本数据进行对比,简述了二者间的差别,并说明原因,且以已有研究为例,具体讨论了数据更替对研究工作的影响.Sunspot is an important external characteristic of solar activity, correlating with other indicators for solar activities. Sunspot is widely studied in the field of solar activity, space environment, solar-terrestrial relationship and climate. International relative sunspot number is the longest time series observed in various sunspot data, playing an important role in many studies. In 2015, the international relative sunspot number was completely revised and a new version was published. Many differences between old and new versions have been noted, which may have considerable impacts. A comparison was made, differences and the reasons and sources of such differences were analyzed. Two reports were analyzed to assess the impact of data revision.
