论文摘要
对于2017年9月6日的耀斑（Sol2017-Sep-06T11：53），我们不仅提出了不寻常的无线电爆发，而且还提出了它们与EUV，White-Light，X射线和$γ$ ray-Ray-Ray-Ray-Ray-Ray-Ray-Ray-Ray-Rays的有趣时间相关性。使用基于小波的新方法，我们在分析的无线电光谱的整个时频域的几个位置中发现了准周期性脉动（QPP）（11：55-12：07 UT和22-5000 MHz）。其中，漂流的QPP是新的，最有趣的是，尤其是硬X射线和$γ$ ray峰时的双向QPP，以及Sunquake的开始。在冲动前阶段，我们显示出与磁绳相互作用引起的EUV亮度相关的异常漂移搏动结构（DPS）。在耀斑冲动阶段，我们发现了一个异常的无线电爆发从5000 MHz漂移到800 MHz。与这种漂流爆发有关，我们在大约在EUV扭曲的结构的发作时间和漂移的无线电爆发的情况下显示了U-Burst，作为高频（1050-1350 MHz）的冲击波的标志。在峰值耀斑阶段，我们发现了一个额外的释放过程，位于太阳大气中的高度较高。考虑到磁绳，磁波和颗粒梁的上升，这些现象被解释了。使用密度模型，我们估计了双向漂移QPP的密度，波速和源高度，抗冲动性DPS和U-Burst的密度以及漂流无线电爆发的密度和磁场强度。
For the 2017 September 6 flare (SOL2017-Sep-06T11:53) we present not only unusual radio bursts, but also their interesting time association with the other flare phenomena observed in EUV, white-light, X-ray, and $γ$-ray emissions. Using our new method based on wavelets we found quasi-periodic pulsations (QPPs) in several locations of the whole time-frequency domain of the analyzed radio spectrum (11:55-12:07 UT and 22-5000 MHz). Among them the drifting QPPs are new and the most interesting, especially a bi-directional QPP at the time of the hard X-ray and $γ$-ray peaks, and a sunquake start. In the pre-impulsive phase we show an unusual drifting pulsation structure (DPS) in association with the EUV brightenings caused by the interaction of magnetic ropes. In the flare impulsive phase we found an exceptional radio burst drifting from 5000 MHz to 800 MHz. In connection with this drifting burst, we show a U-burst at about the onset time of an EUV writhed structure and a drifting radio burst as a signature of a shock wave at high frequencies (1050-1350 MHz). In the peak flare phase we found an indication of an additional energy-release process located at higher altitudes in the solar atmosphere. These phenomena are interpreted considering a rising magnetic rope, magnetosonic waves and particle beams. Using a density model we estimated the density, wave velocities and source heights for the bi-directionally drifting QPPs, the density for the pre-impulsive DPS and U-burst, and the density and magnetic field strength for the drifting radio burst.
