结果表明，大磁暴的主相由两部分组成，最明显的特征是其衰减率：一个比另一个衰减得快得多。研究表明，异常强烈的风暴在很大程度上是由于快速衰减部分的异常生长所致。由于它的快速衰变，与慢衰变部分的结合使衰减率发生了相当剧烈的变化，这在大风暴中是常见的。根据现有的理论知识对结果进行了讨论。
It is shown that the main phase of great magnetic storms is composed of two parts, most clearly characterized by their decay rate: one decays much more rapidly than the other. It is suggested that extraordinarily intense storms are largely due to an abnormal growth of the rapidly decaying part. Because of its rapid decay, the combination with the slow decay part gives a rather sharp change of decay rate, which is commonly seen for great storms. The results are discussed in the light of present theoretical knowledge.
