| 摘 要： | 在电流片两侧的基态速度场与磁场相互平行的位形下,讨论了速度切变对撕裂模不稳定性的影响.结果表明,只有当速度场的相对变化率与磁场的相对变化率符号相同(Sign(v_0/v_0)=sign(B_0~')),|v_0~'/v_0|≥|B_0'/B_0|时,速度切变有利于不稳定增长,否则不利于不稳定增长.

| Abstract: | The influence of shear flow along the magnetic field accompanied with a plane current layer on the tearing instability is analyzed. It is pointed out that the shear flow is favourable to the tearing mode instability only when the rate of velocity is the same sign as the rate of magnetic field B'0/B0 and |
