| 摘 要： | 本文采用把流函数按到磁轴的距离展成幂级数的办法,研究了具有小三角变形椭圆截面的轴对称环状等离子体的MHD平衡和局部模不稳定性问题。文章分析了位形的最优化,给出了最佳的三角变形因子。分析表明,适当选择三角变形因子,会使欧姆加热得到显著的增益。

| Abstract: | Expanding the magnetic flux in terms of the deviation from the magnetic axis, we have studied the MHD equilibrium and localized mode instability of an axial symmetric plasma torus with a small triangular and elliptical deformation on its cross-section. The optimization of the configuration has been analyzed and an optimal factor of the triangular deformation has been given. Our analysis shows that it is possible to strengthen ohmic heating substantially by selecting suitable factors of the triangular deformation. |
