摘　　要：反场构形(FRC)预加热磁化等离子体是磁化靶聚变(MTF)中等离子体靶的主要形成方法之一。为了从物理机理及物理本质上更好地理解反场构形磁化等离子体的平衡状态,依据FRC等离子体的经典刚性转子(RR)模型,通过对平衡状态的解析求解,获得了等离子体各主要参数在平衡状态下的分布函数,并与标准二维磁流体力学(MHD)的数值模拟结果进行对比分析,在此基础上讨论了RR模型参数对平衡状态分布函数的影响。结果表明,在FRC等离子体分界线内部,RR解析模型可以较好地描述等离子体状态分布。The field reversed configuration（FRC） is a toroidal magnetic confinement system in which a pre-heated and mag- netized plasma target can be produced in a 0-pinch coil. FRC is the main approach to the so-called magnetic target fusion. To un- derstand the physical mechanism of its plasma equilibrium better, this paper focuses on the classical rigid rotor（RR） model of the FRC and analytically solved the equilibrium distribution functions. Based on the comparison with the standard two dimensional magnetohydrodynamics（MHD） simulation, the influences of the various RR model assumptions on the equilibrium distribution functions have been discussed, and a calculated expression of the model profile variable with the relative radius was derivated. The results show that the FRC plasma RR model can describe the parameter distribution well within the plasma separatrix.
