摘要
本文介绍了一种用正问题代码通过某种逆过程来求解逆问题的数值方法。我们使用这种方法在平衡代码SWEQU的基础上开发了一个名为SWSTAB的计算非圆截面托卡马克等离子体竖直不稳定性的程序。利用该程序我们计算了成型线圈条件下,上下不对称等离子体的竖直不稳定性,研究了等离子体形状因子(椭圆半轴比,三角形变)及等离子体与成型线圈之间距离对稳定性的影响,方便地得到了用其它方法不易得到的物理结果。
A mathematical method of Using the Code of direct question to Solve inverse question is described. With this method on the basis of free-boundary toroidal MHD equilibrium Code SWEQU We developed our own Code SWSTAB, Which can be used to calculate vertical instability of Tokamak plasma with noncircular cross section. Practical examples show that Some physical results are obtained by this method more easily than by others.
