THE STATIC STABILITY OF PLASMA
等离子体的静态稳定性

In this article, the effects of the small magnetic field perturbation on the equilibrium of plasma are discussed (the problem of the static stability of plasma). It is pointed out that a large variation in the equilibrium configuration may take place only when the small magnetic perturbations couple with the plasma modes which are almost neutally stable. Accordingly, the effects of the main classes of the stray field in Tokamak devices are analysed.
