摘要
利用北京天文台高时间和高频率分辨率的射电频谱仪对射电尖峰的测量，可以对背景等离子体参数进行的自洽诊断（ 磁场，密度，温度，波矢，及非热电子的性质） 。该诊断基于电子回旋脉塞不稳定性和回旋共振吸收。最后从诊断结果和太阳日冕典型参数的比较以确定尖峰辐射的谐波数。
The measurements of the radio spikes with high time and frequency resolution by the spectrometer in Beijing Observatory may provide a self consistent diagnosis for the ambient plasma parameters (magnetic field,density,temperature,wave vector,and the properties of nonthermal electrons).The diagnosis is based on the theories of the electron cyclotron maser instability and cyclotron resonance absorption.The harmonic number of the spike emission is confirmed by the comparison of the diagnosis with the typical parameters in solar corona.
