摘      要：The generation of magnetic fields of galaxies is usually described by the dynamo *** process is characterized by the Steenbeck-Krause-Radler equation,which is the result of averaging the magnetohydrodynamics equations by distances which are associated with the size of turbulent cells in the interstellar *** equation is quite difficult to solve both from an analytical and numerical point of *** galaxies,the no-z approximation is widely *** describes the magnetic fields in thin *** such objects,where it is important to study the vertical structure of the field,it is not very applicable,so it is quite useful to adopt the RZ-model,which takes into account the dependence of the distance from the equatorial *** our research we have obtained the critical values of the dynamo number for galaxies with large *** have also described typical z-structure for the magnetic ***,we have demonstrated that it is possible to generate dipolar magnetic fields.
