聚变等离子体中的能级交叉、过剩时间和瞬态等离子体-壁相互作用
Level crossings, excess times and transient plasma-wall interactions in fusion plasmas
摘要：
基于磁约束等离子体边界区间歇涨落的随机模型，由过程及其导数的联合分布导出了能级穿越率的表达式。由此获得进程在某个阈值水平以上所花费的平均时间。这提供了新的预测等离子体壁的相互作用，由于瞬态传输事件与径向运动的斑点状结构的刮落层。
英文摘要：
Based on a stochastic model for intermittent fluctuations in the boundary region of magnetically confined plasmas, an expression for the level crossing rate is derived from the joint distribution of the process and its derivative. From this the average time spent by the process above a certain threshold level is obtained. This provides novel predictions of plasma-wall interactions due to transient transport events associated with radial motion of blob-like structures in the scrape-off layer.
