| 摘 要： | 用Greene,Johnson和Weimer的方法重新推导了各向异性托卡马克等离子体中的Grad-Shafranov平衡方程。从广义能量原理分析了各向异性高能粒子分量对托卡马克等离子体内扭曲模的稳定作用,并以能量慢化分布和压力随方位角变化基本呈方形的两种高能粒子分布为例仔细计算了此作用,找出了迴转点在强场一侧的高能俘获粒子对托卡马克等离子体内扭曲模的稳定窗口,并深入讨论了它与各物理参数的依赖关系。关键词：

| Abstract: | The Grad-Shafranov equilibrium equation for an anisotropic Tokamak plasma is rederived using the method of Greene, Johnson and Weimer. The stabilizing effect of the anisotropic energetic particle component on the internal kink mode in the Tokamak plasma has been analyzed with the generalized energy principle. Detailed calculation on this effect is performed for two kinds of energetic particle distribution function of slowing down in energy and square top poloidal pressure profile. The stability window of internal kink mode due to the energetic trapped particles with magnetic turning point at high field side is obtained. It's relation with various physical parameters is discussed in some depth. |
