论文摘要
The paper suggests certain regimes of fusion plasma with magnetic confinement, when the Larmor radius $λ$ and the angle $α$ (determining the orientation of the local coordinates) form an analytic function $w=λe^{iα}$ of complex variable $z=x_1+i x_2$ ($x_1$ and $x_2$ are coordinates of tokamak cross-section).众所周知，有效的核融合需要运输障碍，这可能是由于纬向/多核流引起的。而且这种流动的出现是由绝热的额外保护（在当地slub中建立）所暗示的。建议的分析制度基于此额外保护的全球扩展；运输壁垒可能会传播到整个Tokamak等离子体上。有趣的是，在这些方案中，等离子温度通常在单个位置（Tokamak横截面），而是在几个点上被较低温度区域隔开。
The paper suggests certain regimes of fusion plasma with magnetic confinement, when the Larmor radius $λ$ and the angle $α$ (determining the orientation of the local coordinates) form an analytic function $w=λe^{iα}$ of complex variable $z=x_1+i x_2$ ($x_1$ and $x_2$ are coordinates of tokamak cross-section). It is known that an efficient nuclear fusion requires transport barriers, which might be due to zonal/poloidal flow; and the emergence of such flow is implied by the adiabatic extra conservation (established in a local slub). The suggested analytic regimes are based on the global extension of this extra conservation; transport barriers could spread to the entire tokamak plasma. It is interesting that in these regimes, plasma temperature reaches maximum often not at a single location (of tokamak cross-section), but at several points separated by regions of lower temperature.
