我们报告了对太阳活动周8-22期间发生在太阳北方和南方半球的各种太阳现象的研究。我们计算了几种太阳现象的N-S不对称指数，并将它们与太阳活动周数作图。研究表明，南北不对称性具有110年左右的长期特征时间尺度。对这种南北不对称周期的解释是不可用的;它可能是由于太阳内部的不对称磁结构
We report a study of various solar phenomena occurring in both northern and southern hemispheres of the Sun for solar cycles 8-22. We have calculated the N-S asymmetry indices for several solar phenomena and plotted them against the number of solar cycles. The study indicates that the N-S asymmetry has a trend of a long-term characteristic time scale of about 110 yr. An explanation for this N-S asymmetry period is not available; it may be due to the asymmetric internal magnetic structure of the Sun
