| 摘 要： | 本文用数值方法研究了位形存在两个共振面时电阻流体活动的特性。计算是在不同电流分布和不同电导率的情况下,对m=2的扰动做的。结果表明,电阻MHD活动的特征及其增长率不仅依赖于电导率的大小和电流径向剖面峰化的程度,而且依赖于两个共振面之间磁垒的高低。文中还详细介绍了数值方法,这个方法已用于研究撕裂模的非线性演化。

| Abstract: | It can be shown that the dynamics of magnetic perturbation at the nonmonoto-nous profile of a current in tokamak is qualitatively different from that of normal profiles. Behaviour of the perturbation depends on the helical magnetic currents localized mainly between the two singular surfaces. In this paper the numerical method developed to study the non-linear evolution of tearing modes is described in detail. |
