强直流中的载流等离子体磁场在超过一定阈值时会受到剧烈干扰。目前难以验证，通常从“撕裂模式”方面寻求解释。另一种解释是逆磁螺旋级联，它是由各种可能的小规模 MHD 湍流来源产生的。强各向异性 MHD 等离子体可以通过施特劳斯方程来描述。与 MHD 和流体力学的早期示例并行，寻找斯特劳斯方程的湍流逆级联行为的迹象。
Current-carrying plasmas in a strong d.c. magnetic field are subject to violent disruptions above certain thresholds. At present difficult to verify, explanations are typically sought in terms of "tearing modes". An alternative explanation is in terms of inverse magnetic helicity cascades, generated from a variety of possible sources of small-scale MHD turbulence. Strongly anisotropic MHD plasmas may be described by the Strauss equations. Indications of turbulent inverse cascade behavior for the Strauss equations are sought, in parallel with earlier examples from MHD and fluid mechanics.
