AI 中文摘要
最近一篇论文质疑了费拉罗的标准结果，即在旋转轴对称磁镜机器中，等离子体角速度沿单个平衡磁力线近似恒定，在旋转变为声速或超声速时是否仍然成立。为解决此问题，从第一原理出发，使用具有各向异性压力的理想双流体模型研究快速旋转磁镜的平衡。发现只要离子回旋半径远小于机器尺寸，且等离子体角速度远小于离子回旋频率，费拉罗结果就成立。
英文摘要
A recent paper [Hazeltine, et al., Phys. Plasmas 33, 072501 (2026)] has questioned whether the standard result, (ultimately) due to Ferraro, that the plasma angular velocity is approximately constant along individual equilibrium magnetic field-lines in a rotating axisymmetric magnetic mirror machine, continues to hold when the rotation becomes sonic or supersonic. In order to resolve this issue, the equilibrium of a rapidly rotating mirror is investigated, starting from first principles, using an ideal two-fluid model with anisotropic pressure. It is found that, as long as the ion gyro-radius is much less than the machine size, and the angular velocity of the plasma is much less than the ion gyro-frequency, the Ferraro result holds good.
