在以限制器为界的圆形截面等离子体中，即使在边缘电子温度逐渐降低的情况下，在辅助加热期间等离子体电流的快速下降也会触发{H}模式转变。这一结果表明，这种转变是由等离子体边缘附近磁切变的增强所控制的，并与边缘电流密度分布的径向改变有关。
In a circular cross-section plasma bounded by a limiter, the {ital H}-mode transition is triggered by a rapid rampdown in plasma current during auxiliary heating, even in the case when the edge electron temperature gradually decreases prior to the transition. This result suggests that the transition is governed by the enhancement of the magnetic shear near the plasma edge, associated with the radial modification of the edge current-density profile.
