Active faults or tectonic lines are clear boundaries between a very active region and a quiet region . 活動(dòng)斷層或構(gòu)造線是強(qiáng)烈活動(dòng)已和平靜區(qū)之間的清晰邊界。
Gth is the active region gain required to offset losses in the regions exterior to the active region . Gth是為了補(bǔ)償在有源區(qū)以外的區(qū)域中的損失所要求的有源區(qū)增益。
Active regions are in a sense the fundamental unit of solar activity and the most persistent and visible manifestation of solar magnetism . 在某種意義上說(shuō),活動(dòng)區(qū)是太陽(yáng)活動(dòng)的基本單位,也是太陽(yáng)磁性最持久的和看得見(jiàn)的表現(xiàn)形式。
