摘要
我们研究了托卡马克等离子体进制电子引起的电子回旋激射不稳定性发生的条件，发现由反常多普勒效应及切伦科夫效应确定的准稳态速度分布又会激发电子回旋激射不稳定性，且其对本底电子回旋辐射的放大频段低于回旋频率，这与ＨＬ－１实验观察一致。
The electron cyclotron maser instability for runaway distribution function of tokamak plasma has been studied. It proves that the quasisteady velocity distribution function determined by the anomalous Doppler and Cherenkov effects would trigger the electron cyclotron maser instability. This instability amplifies the electron cyctron emission at a rather lower frequency in comparison to gyrofrequency. It is cosistent with the experiment results from the HL-l tokamak.
