<正> In this paper, by making use of data from Cooperative Study of the Kurosio and Adjacent Reions (CSK) together with part of the Geomagnetic Electrokinetograph (GEK) surface current observation data, we analyse the E section in detail for the following contents:1. The variation characteristics of time and space in the current field of the Kuroshio.2. The current axis structures of the Kuroshio and its main axis shift to the right with depth. Some parameter indications of the hydrographical elements are presented.3. Comparison is made among the East of Taiwan Island, the Kuroshio in the East China Sea and the Kuroshio crossing the E section.4. The geostrophic transports are calculated and their variations are analysed. The great difference of vertical transport distribution between the warm half year and cold half year is specifically indicated.We think that this paper is of benefit to further studying the Kuroshio and to the exploitation and utilization of its resources.
