摘　　要：本文简要介绍了云南天文台新建立的21cm波段快速(不中断采样)记录系统,及使用该系统观测到的快速尖峰事件。系统得到的太阳分米波段爆发中不同时间尺度的精细结构与Stu-rroch等提出的太阳耀斑中能量释放的模式相一致。The paper presents a brief description of a new recording system with fast (continuous) sampling at 21 cm wavelength at the Yunnan Observatory and the solar fast spike events observed by this system. These events showed that the different fine temporal with different time scales at decimeter wavelength in solar radio burst. The structure is in agreement with the model for energy release in the impulsive phases of solar flares proposed by Sturroch et al. [13].
