利用星系团数据研究了行星际磁场锥角θ和钟角φ对等离子体片边界层场向电流的影响。FAC出现随IMF锥角单调增加，并且分别在-90度和+110度钟角处有两个峰值。+110度处的峰值明显大于90度处的峰值。总体而言，0度之间的FACs较多
The influences of the interplanetary magnetic field (IMF) cone angle theta and clock angle phi on the field-aligned currents (FACs) at the plasma sheet boundary layers (PSBLs) have been investigated using Cluster Data. The FAC occurrence increases monotonically with IMF cone angle and has two peaks at -90 degrees and +110 degrees clock angle, respectively. The peak at +110 degrees is distinctly larger than that at 90 degrees. Overall, there are more FACs between 0 degrees
