研究了螺旋装置中磁场线随机性的三维 (3D) 效应。由于等离子体压力增加而导致的随机化是仿星器/日光管的固有属性，因为压力梯度驱动电流是扰动场的来源。随机化取决于等离子体压力分布。在先进的仿星器中，由于 3D 效应导致的随机化较小。然而，边缘的磁岛会受到 3D 效应的影响。还研究了托卡马克等离子体中的 3D 效应，并发现了与真空近似的差异（© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA，Weinheim）
Three‐dimensional (3D) effects on the stochasticity of magnetic field lines in helical devices are investigated. The stochastization due to increased plasma pressure is an intrinsic property of the stellarator/heliotron because the pressure‐gradient driven currents are the source of perturbation fields. The stochastization depends on the plasma pressure profile. In an advanced stellarator, the stochastization due to the 3D effects is smaller. However, magnetic islands in the edge are affected by 3D effects. 3D effects in a tokamak plasma are studied,too, and differences from the vacuum approximation are found (© 2010 WILEY‐VCH Verlag GmbH & Co.
