摘要：
We have developed a high resolution numerical method based on spectral approximations to study kinematic dynamo models of the galaxy in the geometry of an oblate spheroid. The method has enabled us to investigate the onset of dynamo action in the limit of a thin disk. In this limit we have served the discrepancy between the asymptotic analysis of Soward and the previous numerical works of Stir and White.
