We have carried out the numerical simulation on current sustainment of a field-reversed configuration by a rotating magnetic field. The rotating magnetic field externally applied just after producing the field-reversed configuration by a theta pinch discharge is penetrated rapidly into the FRC,and drive a steady current before it breaks due to Joule dissipation. The threshold of a rotating magnetic field to sustain the equilibrium is as small as 10% of the axial magnetic field. The RMF's with the mode number of m=1 or 2 give the similar results. It has been revealed that the method of applying a RMF to an FRC may be effective for sustaining the hot and dense FRC in a steady state.The equilibrium of a field-reversed configuration (FRC) with the rotating magnetic field (RMF) externally applied for keeping the steady state is also studied theoretically. We have solved the momentum equations of ions and electrons analytically and found the analytical solution of a steady equilibrium of the FRC with the RMF,in which the ions and electrons rotate at the different velocities. It has been revealed that the radial anomalous diffusion neglected in previous studies plays an important role in the equilibrium.The distinguished paper award was conferred on the former study in 16th IEEE/NPSS Symposium on Fusion Engineering held at University of Illinois on October 5,1996.

我们对旋转磁场作用下反转位形的电流维持进行了数值模拟。在通过theta箍缩放电产生场反转配置后，外部施加的旋转磁场迅速渗透到FRC中，并在其因焦耳耗散而断裂之前驱动稳定的电流。维持平衡的旋转磁场的阈值小到轴向磁场的10%。模数为m=1或2的RMF给出了类似的结果。结果表明，在FRC上施加RMF的方法可以有效地维持FRC的热态和致密的稳态。本文还从理论上研究了外加旋转磁场(RMF)的场反转位形(FRC)的平衡。我们对离子和电子的动量方程进行了解析求解，得到了离子和电子以不同的速度旋转的FRC和RMF的稳态平衡的解析解。1996年10月5日，在伊利诺伊大学举行的第16届IEEE/NPSS聚变工程研讨会上，发现了以往研究中忽略的径向反常扩散在核聚变平衡中的重要作用。
