摘要：
A surface-localized mode governing resistive drift-Alfven mode is experimentally observed in a collisional, current-carrying finite-beta plasma, accompanied by an electron diamagnetic-drift frequency spectrum. The halfwavelength travelling along the plasma column with the Alfven velocity determines the Alfven mode. The spatial distribution and the phase relation of magnetic components are presented.
