本文详述了ＨＬ－１托卡马克等离子体在低混杂波驱动（ＬＨＣＤ）和电子回旋波加热（ＥＣＲＨ）条件下不同特征频率上的微波非热辐射。欧姆放电下，分析了由速度各向异性引起的反常多普勒不稳定性，实验观察了在ＬＨＣＤ和ＥＣＲＨ条件下这种不稳定性的行为。运用反常多普勒不稳定性产生条件，本文讨论了ＬＨＣＤ条件下这种不稳定性受到抑制的可能物理机制。
This paper details the microwave non-thermal radiation of HL-1 tokamak plasma at different eigenfrequency under the low hybrid noise driven (LHCD) and electron cyclotron heating (ECRH) conditions. Under the ohmic discharge, the anomalous Doppler instability caused by velocity anisotropy was analyzed. The instability behavior under LHCD and ECRH conditions was observed experimentally. By using the conditions of anomalous Doppler instability, we discuss the possible physical mechanism that this instability is suppressed under LHCD conditions.
