摘要

The in situ, large scale, electric and magnetic field measurements performed by the ISEE-1 satellite at the magnetosheath-magnetopause-magnetosphere interface, from 01.00 to 01.44 hours UT of day 324, 1977, are used to infer average behaviors of those fields and of their related ExB flows, and to study general properties of the large scale reconnection process at the magnetopause, as described by reconnection models. It is mainly concluded that about 40% of the magnetosheath magnetic field lines seem to participate in the reconnection process (a reconnection rate about twice as much as that predicted by the Petschek model); that the post-reconnection flow rate is about that predicted by the Petschek model; and that the tilting of the reconnection line off the y-axis (in solar magnetospheric coordinates) is somewhat smaller than that predicted by the Gonzalez and Mozer model.
