摘　　要：在一次稳定放电过程中利用快速扫描气动探针系统得到电子温度、密度、等离子体电位、极向电场以及它们的涨落、粒子通量、能量通量在径向的分布。研究了HL-2A装置边缘的静电涨落及其输运。实验结果指出,在等离子体边缘涨落量不服从玻耳兹曼关系,存在由于等离子体空间电位的梯度所产生的径向电场剪切层。分析了涨落对边缘约束的影响。The electrostatic fluctuation and related transport at the edge of HL-2A plasma have been investigated using the parameters such as electron temperature, electron density, plasma potential, their fluctuations, particle flux and energy flux, which are simultaneously measured in a single steady shot by means of fast reciprocating probe system. Analyzed fluctuation features including the Boltzmann relationship of edge parameters, the radial electron-field shearing induced by the gradients of plasma potential, and the influence of fluctuations on edge confinement are given.
