摘 要:
研究了旋转磁场电流驱动理论模型中离子运动的影响。考虑无限长的等离子体柱，在二维（r，θ）磁流体理论模型的基础上，采用电子运动方程和离子运动方程，并考虑离子的径向运动速度，建立了新的二维磁流体理论模型。然后把得出的结果与离子静止模型下的结果进行比较，并讨论了相应的物理过程。这个模型同样适用于平行于磁场线（Z方向）的流动效应和场旋转位形的压力平衡的理论计算。[著者文摘]

Abstract:
Effect of the ion motion is studied in the theoretic model of rotating magnetic field as a current drive mechanism. On the basis of 2-D MHD model, the ion and electron motion equations are applied in infinitely long cylindrical geometry, and therefore a new 2-D MHD theory is built by taking account of ion radial motion. The calculated results are compared with ones obtained from fixed ion model, and the corresponding physical processes are discussed. This improved theoretic model can be adapted to the parallel flow （along the magnetic field line） effects and the axial pressure balance.[著者文摘]
