摘　　要：本文分析了1989年3月9日,11日,13日与AR5395产生的耀斑成协的,叠加在2cm微波爆发上的具有双峰结构的准周期振荡.利用磁流环结合的非线性不稳定性机制,对等离子体和磁场相互作用的过程进行了定性的分析,并计算了几个有关的参数.最后进行了简单的讨论.The quasi-periodic amplitude oscillations with double peak structures superimposed on the radio bursts have been analysed. These double peak structures were associated with the flare at AR 5395 on 9, 11 and 13 March 1989.Using the mechanism of non-linear current loop coalescence instability, the interaction between plasma and magnetic field has been analysed, several parameters have been calculated, and a simple discussion has been presented.
