论文摘要
黑子周期是发电机过程产生的太阳的磁性周期。太阳发电机的一个核心思想是，太阳的环形和多磁场相互维持。我们讨论了黑子的相关观察数据（这是环形磁场的表现）和太阳的poloidal场。我们指出，太阳的差异旋转如何伸出多背球，主要在对流区域的底部产生环形场，而由于磁性浮标产生日光点，因此该环形场的一部分可能会上升。在通量传输元模型中，倾斜的双极太阳突的衰减通过Babcock-Leighton机制引起了多型球场。在这种类型的模型中，太阳的子午循环在太阳表面是极点的，在对流区域的底部赤道，在磁通的运输中起着至关重要的作用。我们最终指出，与发电机过程相关的各种随机波动可能在产生黑子循环的不规则性方面起关键作用。
The sunspot cycle is the magnetic cycle of the Sun produced by the dynamo process. A central idea of the solar dynamo is that the toroidal and the poloidal magnetic fields of the Sun sustain each other. We discuss the relevant observational data both for sunspots (which are manifestations of the toroidal field) and for the poloidal field of the Sun. We point out how the differential rotation of the Sun stretches out the poloidal field to produce the toroidal field primarily at the bottom of the convection zone, from where parts of this toroidal field may rise due to magnetic buoyancy to produce sunspots. In the flux transport dynamo model, the decay of tilted bipolar sunspot pairs gives rise to the poloidal field by the Babcock--Leighton mechanism. In this type of model, the meridional circulation of the Sun, which is poleward at the solar surface and equatorward at the bottom of the convection zone, plays a crucial role in the transport of magnetic fluxes. We finally point out that various stochastic fluctuations associated with the dynamo process may play a key role in producing the irregularities of the sunspot cycle.
