研究了HL-2A在中性束注入(NBI)和电子回旋共振加热(ECRH)过程中的离子和电子鱼骨不稳定性特征。文中提出了一些新的现象，如跳频、V字型扫频等。在NBI过程中，已经鉴定出三种I-鱼骨，包括杂交锯齿-鱼骨(锯骨)、运行的鱼骨和经典鱼骨。实验结果表明，在高功率(PECRH>；0.7 mW)回旋回声过程中，e-鱼骨的频率高于低功率回旋回声时的频率，并具有上下啁啾行为，有时还存在V字形扫频。周期模式频率跳跃也已被软X射线阵列探测到。有可能把这些现象与高能电子的重新分布联系起来。
The features of ion and electron fishbone instabilities have been investigated during neutral beam injection (NBI) and electron cyclotron resonance heating (ECRH) on HL-2A. Some new phenomena, such as frequency jumps and V-font-style sweeping, have been presented in the paper. Three kinds of i-fishbones, including hybrid sawtooth–fishbone (sawbone), run-on fishbone and classical fishbone, have been identified during NBI. During high power (PECRH > 0.7 MW) ECRH, the experimental results indicate that the e-fishbone frequencies are higher than those during low power ECRH, and are provided with up- and down-chirping behaviours, and sometimes also with V-font-style sweeping. The periodic mode frequency jumps have also been detected by a soft x-ray array. It is possible to correlate these phenomena with the redistribution of energetic electrons.
