本文报道了PDD等离子体中脱离锋的一维随时间变化的分析结果。详细讨论了偏滤器区域中的交叉场粒子和能量输运对部分分离等离子体的影响。结果表明，偏滤器区的这种输运效应可以阻止脱离前锋向上游移动，并且稳定状态下脱离前锋的位置相对于偏滤器区的中性密度是热不稳定的。
Results of one-dimensional time dependent analysis of a detachment front in a PDD plasma are reported. Effects of the cross-field particle and energy trasport in a divertor region on a partially detached plasma are particularly discussed. It was found that such transport effects in the divertor region can prevent the detachment fronts from moving upstream, and that the position of the detachment front in a steady state is thermally unstable against the neutral density in the divertor region.
