Abstract
The peeling–ballooning (P–B) mode has been thought to play an essential role in causing the type-I edge-localized modes (ELMs) in the H-mode plasmas, although firm experimental evidences of the P–B mode as a cause of Type-I ELMs have not been provided. In this letter, we examine the dynamical evolution of the P–B mode when the plasma parameters come across the linear stability boundary. It is noted that the P–B mode model has some limitations to explain all of the trigger of Type-I ELMs.
剥离-膨胀（P-B）模式一直被认为在导致H模式等离子体中的I型边缘定位模式（ELM）中扮演着重要角色，尽管P-B模式作为I型ELM的成因还没有确切的实验证据。在这封信中，我们研究了当等离子体参数跨越线性稳定边界时 P-B 模式的动力学演变。我们注意到，P-B 模式模型在解释 I 型 ELM 的所有触发因素方面有一定的局限性。
