论文摘要
核心等离子体对$ω<ω_{BAE} $激发的激发的共振和非谐振作用，例如β诱导的Alfvén声学特征模式（BAAES）和动力学气球模式（KBMS）（KBMS）在框架中在框架中在框架中在框架中进行了框架。鱼骨状方程的形式主义包含描述这些低频波动特征的所有必要成分，并解释了实验发现。核心等离子体特性（被捕获离子的磁性频率和进动的共振）强烈影响模式的激发，而在Baaes的情况下，比能量颗粒更有效地影响了Baaes的激发。核心等离子体的磁磁频率也有助于BAAE与KBM的耦合，从而影响两种模式的激发和极化。能量颗粒仍然可以为某些低频模式提供非共振驱动器。
The resonant and non-resonant effects of core plasma on the excitation of low frequency modes with $ω< ω_{BAE}$, such as Beta-induced Alfvén Acoustic Eigenmodes (BAAEs) and Kinetic Ballooning Modes (KBMs) are examined in the framework of the generalized fishbone-like dispersion relation. The formalism of the fishbone-like equation contains all the necessary ingredients to describe the features of these low frequency fluctuations, and explain experimental findings. Core plasma properties (diamagnetic frequency and precession resonance with trapped ions) strongly affect the excitation of the modes, and in the case of BAAEs more effectively than the energetic particles. The diamagnetic frequency of the core plasma also contributes to the coupling of the BAAEs with the KBMs, thus affecting the excitation and polarization of both modes. Energetic particles can still provide a non-resonant drive to some of the low frequency modes.
