Zero frequency zonal flow (ZFZF) excitation by trapped energetic electron driven beta-induced Alfvén eigenmode (eBAE) is investigated using non-linear gyrokinetic theory. It is found that, resonant energetic electrons (EEs) not only effectively drive eBAE unstable, but also contribute to the non-linear coupling, leading to ZFZF excitation. The trapped EE contribution to ZFZF generation is dominated by EE responses to eBAE in the ideal region, and is comparable to thermal plasma contribution to Reynolds and Maxwell stresses.
捕捉高能电子驱动的β诱导阿尔芬本征模（eBAE）对零频带状流（ZFZF）的激发，采用非线性回旋动理学理论进行了研究。研究发现，共振高能电子（EE）不仅能有效驱动eBAE不稳定，还通过非线性耦合对ZFZF的激发作出贡献。捕获高能电子对ZFZF生成的贡献，主要由理想区域中eBAE的电子响应主导，且与热等离子体对雷诺应力和麦克斯韦应力的贡献相当。
