摘要
本文比较了Krall方法和势场方法判断横场方向的优劣,得出后者比前者有更高的准确率。并且对AR_(5312)活动区1989年1月14日的耀斑和纵向电流密度之间的关系进行了分析,结果为H_β初始亮点和光球纵向电流密度极大值之间有对应关系。
In this paper, we compare the methods of Krall and potential field in order to estimate the direction of transverse field, and find the latter method is better than the former in estimating the directions. We analyse the relation bstween the flare and longitudinal current density in AR5312 active region on Jan. 14, 1989, and obtain the results that initial bright points in Hβ correspond to the largest value of longitudinal current density in photosphere.
