摘　　要：MHD(Magneto hydrodynamic,磁流体力学)不稳定性是托卡马克磁约束聚变等离子体中的基本物理现象,是影响装置放电稳定性及等离子体约束性能的重要因素,通过磁探针诊断对球形托卡马克上的Mirnov扰动进行测量和分析,并利用外加偏压导体方法首次对扰动进行抑制。Magneto hydrodynamic （MHD） instability is essential features in the magnetical confinement tokamak plasma, and it plays an important role in discharge stabilization and plasma confinement. The Mirnov fluctuations are measured and analysed by magnetic measurement system on Spherical Tokamak. And the restrain of the fluctuations by applying a bias electrode is presented.
