| 摘 要： | 运用二维可压缩磁流体动力学（MHD）模拟方法考察了周期性多电流片系统中涡旋诱发重联（VIR）过程的发展演化．结果表明，相邻电流片中的VIR过程发生相互作用，相距越近，作用越强烈．反对称和对称波模VIR过程的线性增长率随电流片间距的减小而分别增大和降低．当电流片间距小于某临界值时，反对称波模VIR完全被抑制．相对于对称波模VIR，反对称波模VIR过程对空间多电流片系统的发展会发挥更大作用．

| Abstract: | The vortex induced reconnection(VIR) processes in periodic current sheet systems with shear flows at near and supper Alfven speed are investigated by using the two dimensional compressible magnetohydrodynamics(MHD) simulation method. The results show that, the VIR processes in the neignbouring current sheets can interact with each other, and their linear growth rate is enhanced and decreased for the cases of antisymmetric and symmetric modes, respectively. |
