摘要：
This paper describes examination of certain linear and nonlinear properties of macroscopic tearing modes driven by anomalous electron viscosity effects associated with magnetic braiding. It is shown that strong linear growth of m=1,2 tearing modes (respectively proportional to 15 and 13 can occur for rather modest values of. In the nonlinear phase, the island width grows in time as t13. Some speculations regarding the disruptive instability in tokamaks are also investigated. © 1979 The American Physical Society.
