摘要：
The tokamak shaping effects on the toroidal branch of the ion-temperature-gradient-driven mode in the long wavelength limit (k(chi)2rho(i)2 much less than epsilon(T)1/2) are studied. A model equilibrium with noncircular cross section is employed, where elongation, Shafranov shift, and triangularity are all taken into account. It is shown that each Fourier term in the expansion of the equilibrium magnetic field is associated with a new branch of the dispersion relation.
