磁层顶极尖区的理论探讨

本文解出了三维磁层顶的Chapman-Ferraro模型。证明极尖区有一条极尖线,长约40°。磁尖线上磁层顶呈尖角。磁层磁力线由极尖线上各点通往磁层顶。通常所谓中性点,足极尖线在日地子午面的截点。 

THEORETICAL TREATMENT OF THE MAGNETOPAUSE CUSP

Chapman-Ferraro model is solved for a three dimentional magnetopause.It is proved theoretically that there is a demarcation line with definite length of about 40° through the cusp region.The surface of the magnetopause is angled along this line,on which every point is an exit for the earth's field line to emerge from the magne-tosphere.The neutral point is just the intersection of the demarcation line by the meridian plane.
