等离子体约束对丁边缘条件是非常敏感的。简单地说,理论试图解释剪切流和L-H模转换的焦点集中在扰动诱导的边缘雷诺胁强Rs、极向流速vpol和径向电场Er的结构上[1]。等离子体与孔兰相互作用所引起的离子轨道损失以及粒子和动量源的极向不对称足产生极向旋转的重要机制之一。雷诺胁强是测定托卡马克等离子体边界扰动结构的非均质性 Plasma confinement is very sensitive to the edge conditions. Briefly, the theory attempts to explain the focus of shear flow and L-H mode conversion on the structure of disturbance-induced edge Reynolds stress Rs, poloidal flow vpol, and radial electric field Er [1]. One of the important mechanisms that produce polar rotation due to the ion orbit loss caused by the interaction between the plasma and the pore and the polar asymmetry of the particle and momentum source. The Reynolds stress is a measure of the heterogeneity of the perturbed structure at the Tokamak plasma boundary
