摘要

基于理想磁流体力学外区解的结构，自然推导出环面耦合撕裂模式下包括压力和其他O(2)阶修正的一般色散关系。研究发现，在e矩阵的对角线元素中加入O(2)阶项并不会改变环向耦合撕裂模式的物理性质，对生长速率大小的贡献可以忽略不计。

Influence of higher order toroidicity on coupling of tearing modes

The general dispersion relation for toroidally coupled tearing mode including pressure and other O(2) order corrections is naturally derived based on the structure of ideal magnetohydrodynamic solutions in the outer region. It is found that the inclusion of the O(2) order terms in the diagonal element of E-matrix does not change physical properties of the toroidally coupled tearing mode and only make negligible contribution to the magnitude of growth rate.
