新的国际太阳黑子编号(NISN)已成功汇编,可从布鲁塞尔比利时皇家天文台世界数据中心--太阳黑子指数和长期太阳观测下载。用Lomb-Scargl型周期图研究了这些NISN的周期。结果表明,国际太阳黑子数具有很大的周期。在各周期中,最显著的是去掉10.108年信号后的11年左右的周期,也有11.988年、7.990年、9.612年、5.445年、8.915年、5.792年的周期,其中5.445年的周期比5.792年和8.915年的周期强。然而,5.445年的周期仍然比10.862年的周期弱得多。显然,用Lomb-Scarger周期图法得到的修正国际黑子数的11年和5.5年左右的周期与以往的研究有所不同。
The New International Sunspot Numbers (NISNs) have been successfully compiled and can be downloaded from the World Data Center-Sunspot index and Long-term Solar Observations, Royal Observatory of Belgium, Brussels. The periods in these NISNs have been studied by using the Lomb–Scargle periodogram. The results show that the international sunspot numbers have a lot of periods. Of the various periods, the most outstanding period around 11 year is 10.108 year after removing the 10.862 year signal from the time series of sunspot numbers, while the periods of 11.988 year, 7.990 year, 9.612 year, 5.445 year, 8.915 year, 5.792 year are also found with the period of 5.445 year being stronger than those of 5.792 year and 8.915 year. However, the period of 5.445 year is still much weaker than the period of 10.862 year. It is evident that the periods around 11 year and 5.5 year in the revised international sunspot numbers obtained by using the Lomb–Scargle periodogram method is somewhat different from the ones in previous studies.
