摘要：

用圆柱位形的磁流体动力学方程对由反常电子粘滞性引起的双撕裂模的线性行为做了数值研究。分析了两个有理面的间距、粘滞率大小和极向模数对双撕裂模模式结构的影响，给出了各种情况下双撕裂模线性增长率跟表征反常电子粘滞率大小的电子雷诺数的定标关系。

Abstract:

The linear behavior of the double tearing mode (DTM) mediated by parallel electron viscosity in cylindrical plasmas with reversed magnetic shear is numerically investigated. The mode structures and dispersion relations for linearly unstable modes are calculated. A detailed analysis of linear instability characteristics of DTMs with various roles, including the inter-resonance distance, the electron viscosity Reynolds number and poloidal mode number, is performed.

Key words: Double tearing mode, Parallel electron viscosity, Numerical simulation
