太阳活动的不对称性研究

Research on the Asymmetry of Spatial Distribution of Solar Activities

从三方面概述太阳活动不对称研究的进展：不对称性的特征及其演化行为、周期性和可能的解释．太阳活动在南北半球及东西半球上的分布是不均匀的，且在南北半球上分布不对称；但目前仍无法确定东西半球分布不对称。在众多的解释太阳活动不对称性的理论中，没有一种理论被广泛接受。对将来开展太阳活动不对称性研究工作提出了一些看法。

In this paper, progress of research on asymmetry of spatial distribution of solar activities, including the north-south asymmetry and the west-east asymmetry, is briefly summauized and discussed at three aspects: features and developing behaviors, cycles and some plausible explanations. Solar activities are not uniformly and symmetrically distributed on the north and south hemispheres, and neither uniformly distributed on th west and east hemispheres. Up to now the result on the asymmetry of spatial distribution of solar activity on the west and east hemispheres can not be confirmed. Some suggestions on future work of studing the asymmetry of the spatial distribution of solar activities are also proposed.
