摘要：
The authors have obtained a solution to the nonlinear MHD equations, which describes a helical magnetic field of arbitrarily large amplitude. The frequency and wave number of this field are not restricted by any particular relation. The stability properties of this large amplitude wave have been considered. This approach enables us to link together parametric instability theory with conventional MHD analysis of spatially varying magnetic fields.
