长久以来，除了这种闪焰与强磁场的关联之外，日焰喷发的详细情形依然模糊不清。
Beyond the general association between flares and strong magnetic fields, the picture of how things work has long remained very fuzzy.
一个理由是日冕中的电阻一般说来是相当低的，低到不足以解释日焰爆发时增亮的程度。
One reason is that the electrical resistance in the corona is typically quite low - too low to account for the explosive rate at which solar flares brighten.
在一些日焰现象中，磁场环圈顶部显现出神奇的尖端，看起来就像是有尖顶的哥德式拱门，而非一般常见的圆顶。
For some of these events the tops of the magnetic loops showed a curious cusp giving them the pointed appearance of a gothic arch rather than presenting the usual rounded peak.
