本文比较了解轴对称平均场αΩ发电机方程的渐近方法和非z近似方法。对于不同的发电机参数和两条不同的旋转曲线，分别在线性和非线性两种情况下讨论了解的行为。从两种不同的方法得到的解被发现是一致的。
Abstract The asymptotic and the no-z approximation methods of solving the axisymmetric mean field αΩ dynamo equation in a galactic disc are compared. The behaviour of the solutions is explored in both the linear and nonlinear regimes for a variety of dynamo parameters and two different rotation curves. The solutions obtained from the two different approaches are found to be in good agreement.
