利用一组马赫探针研究了ＨＬ－１Ｍ装置刮离层（ＳＯＬ）和边缘等离子体流在欧姆放电、壁硼化、偏压抽气孔栏、偏压电极、低杂波电流驱动（ＬＨＣＤ）和电子回旋共振加热（ＥＣＲＨ）等情况下的平行流马赫数、离子饱和电流扰动、平行流速度剪切和极向流速度的分布。
A set of Mach probes was used to study the effects of the SOL and edge plasma flows of the HL-1M device on the ohmic discharge, wall boriding, biased exhaust hole column, bias electrode, low clutter current drive (LHCD) And electron cyclotron resonance heating (ECRH), the parallel flow Mach number, the ion saturation current perturbation, the parallel flow velocity shear and the polar flow velocity distribution.
