Furthermore the " microflare theory " tried to discuss and find the elementary flares in small space and time scale which might form and trigger the whole solar flare . the detection of radio fine structures showed many observational evidences of " microflare " . the observations and theoretical researches on radio fine structure have been developed fast recently and played an important role in solar radio astrophysics 著名的“微耀斑理论” ，试图从较小的时间、空间尺度范围探究太阳耀斑形成和触发的基本单元，而射电精细结构是微耀斑理论的重要观测基础，对射电精细结构的观测和理论研究已成为太阳射电天文学中快速发展的领域，对揭示太阳活动源区的物理本质具有重要的意义。
