摘要：
Poloidal rotation and growth of the toroidally coupled tearing mode are analyzed based on the dispersion relation obtained by Li and Huo [Phys. Fluids B 5, 3737 (1993)]. The dominant (subdominant) branch is most (least) unstable when the frequencies of both unstable harmonics are equal. The poloidal rotation has a stabilizing effect on the subdominant branch through the toroidal coupling with the dominant branch. The stable branch cannot be excited by the poloidal rotation when one or both harmonics are stable. The rotation frequencies of both branches can be mutually locked to the average of, but not one of, both harmonic frequencies when the growth rates of both harmonics are equal. © 1995 American Institute of Physics.
