| 摘 要： | 本文在有理面附近的局域近似下,从MHD方程出发,求出了非线性撕裂模的时间演化的解析结果。大体可划分为三个阶段:线性增长,由非线性因素导致饱和,最终过渡到一个与初始条件无关的非线性特解,并与原有的线性及非线性撕裂模的解析结果进行了比较,在线性近似下可退化到经典的结果。由本文结论还可解释托卡马克的大破裂中的有关现象。关键词：

| Abstract: | With the local approximation near the rational surfaces, the analytical expressions of the evolution of non-linear tearing modes are derived from MHD equations; and are compared with the previous results for linear and non-linear tearing modes. The phenomenon of modulation and anomalous increase is explained, which was found in the experiments of the maor disruptions in Tokamaks. |
