摘　　要：从流体力学方程和电磁场理论出发,导出磁流体动力学方程组,从而清晰得出流体核聚变被磁场约束在一定域内的原理,并以太阳演变为“白矮星”过程为例,阐明箍缩效应在热核聚变反应中的作用.介绍四种典型的磁约束装置,其中无线长圆柱形导电体为理想状态,无法实现,JET是目前正在使用中的世界上最大的托卡马克装置,而未来最有发展前景的可能是串列磁镜组成的巨型马克堆.Based on the equations of fluid dynamics and electro-magnetic field theory, this paper deduces the kinetic equations of magnetic plasma from which the principle that the fluid nuclear fusion is confined within certain space can be presented clearly. The evolution process from a sun to a white dwarf star is taken an example to illustrate the application of pinch effect in nuclear fusion. Four typical setups of magnetic restriction are introduced. JET is the biggest Tokamak currently being utilized in the world. However, the one with the greatest potential application might be the huge Mark Stack consisting of a set of magnetic mirror in serial.
