在具有非麦克斯韦电子分布的等离子体放电中，如在低电子密度的托卡马克中或在加热实验中，利用发射到等离子体中的电磁波的朗道阻尼，测量了介电卫星与Fe x x v中主要光学允许线的线比。在弗拉斯卡蒂托卡马克傅里叶变换中进行的一系列实验清楚地证实了非热电子的作用，并计算出了这些等离子体条件下线强度的表达式。本文还提出了一种数据分析方法，可以给出等离子体中非热电子含量的定量信息。
The line ratio of a dielectronic satellite to the main optically allowed line in Fe x x v has been measured in plasma discharges with a non-Maxwellian electron distribution such as those produced in tokamaks at low electron density or during heating experiments by means of Landau damping of electromagnetic waves launched into the plasma. The effect of nonthermal electrons has been clearly established in a series of experiments performed in the Frascati tokamak FT and the expressions for line intensities in these plasma conditions have been worked out. A data-analysis procedure is also presented which can give quantitative information about the nonthermal-electron content in the plasma.
