【摘要】 日球层电流片的存在已被普遍接受。关于行星际日球层电流片的构形及其成因,即它是日冕高度上日球层电流片在行星际空间的简单延伸还是行星际动力学演化的结果,目前看法尚不一致.本文首先分析日球层电流片的瞬时形态(一个太阳自转周这样的时间尺度上)和平均形态(大于半年这样的时间尺度上),然后提出一个日球层磁合成模式,尝试解释瞬时和平均构形的形成。更多还原

【Abstract】 The average configuration of the heliospheric current sheet in the years of 1974 and 1976 has been figured out. The morphology of the heliospheric current sheets for the individual rotation in Jan. Apr. 1976 has also been analyzed. It is found that the average heliospheric current sheet over a large scale is basically flat and tilted although the heliospheric current sheets for each rotation are generally observed to be warped during the period. Based on the analysed results in the persent work, a synthetic magnetic heliosphere model has been suggested. In the model the magnetic field in the heliosphere consists of two parts, one is a large scale dipole-like component corresponding to the flat current sheet, the other is a small scale component which causes the current sheet warped. The synthetic heliosphere model can be used to understand the observations over different time scales in different measurements and reconcile some controversy in interpreting the observations.更多还原
