叙述了用电子回旋辐射测量电子温度的原理和方法,并给出了在HL1M托卡马克上的不同放电条件下的实测结果。在某些实验条件下,如电流上升、弹丸注入和重杂质聚集,出现了电子温度的中空分布。在托卡马克等离子体边缘加上直流偏压的情况下,观测到电子温度分布变陡。这些现象与等离子体中心的输运有密切的关系。 The principle and method of measuring electron temperature by electron cyclotron radiation are described, and the measured results under different discharge conditions of HL1M tokamak are given. Under some experimental conditions, such as the current rise, projectile injection and heavy impurities, there is a hollow distribution of electron temperature. In the case of a DC bias at the edge of the tokamak plasma, it is observed that the electron temperature distribution becomes steep. These phenomena are closely related to the transport of plasma centers.
