报道了在喷注托卡马克上首次测量了纯离子回旋共振频率(ICRF)加热的H模期间体等离子体的环向旋转。在向H模的转变过程中，沿等离子体电流方向的环向加速度很大。本文研究了环向旋转与改进的H模限制的关系。我们得出结论：离子压力梯度是环向旋转的主要驱动机制。
The first measurements of toroidal rotation of the bulk plasma during purely ion cyclotron resonance frequency (ICRF) heated H-modes on the JET tokamak are reported. Substantial toroidal acceleration in the direction of the plasma current occurs at the transition into H-mode. In the present paper the relationship between toroidal rotation and improved confinement of the H-mode is investigated. We conclude that the dominant driving mechanism for toroidal rotation is the ion pressure gradient.
