摘要：

It is shown that the Rayleigh-Taylor instability of magnetized plasma is nonlinearly stabilized by the external imposition of transverse velocity shear with zero spatial second derivative. The critical velocity shear required for stabilization is of order gamma(g)(ln Ra)1/2, where gamma(g) is the linear growth rate and Ra is the Rayleigh number.
