摘要：

Interchange modes in magnetized plasmas can be stabilized by cross-field velocity shear. This effect is re-examined for systems with elongated cross-sections. For large elongations, E, the interchange growth drops as E-1/2 while the velocity shear scale is still determined by the short scale size. Consequently, velocity shear stabilization of elongated plasmas is shown to be more efficient by E-1/2. (C) 1999 American Institute of Physics. [S1070-664X(99)02310-1].
