bipolar field

The relations between the toroidal magnetic field in the solar convection zone and the bipolar magnetic field of sunspots

太阳对流层内的纬向磁场与黑子双极磁场的关系

The initial magnetic field is taken to be a force-free field, consisting of an isolated flux rope attached to the base and a bipolar background field surrounding it.

初始时背景场为无力场，磁绳附着于光球表面，外部为双极场。

A flux rope is introduced within each bipolar field.

每个双极场内部各有一根磁绳，它们均附着于光球表面。

These results differ from those for the bipolar background field case, in which the catastrophic energy threshold is almost independent of the magnetic fluxes of the flux rope and the extent to which the background field is open.

这与偶极场背景下的结果不同。在偶极背景场下，系统的灾变能阈与灾变点处磁绳的磁通和背景场的开放程度几乎没有关系。
