按照 Malkus 和 Proctor (1975) 的规定，将地球发电机的 α 效应模型扩展到非线性区域。在该模型中，小尺度动力学对 α 效应的影响被抑制，并且单独检查诱发速度场的全局效应。使用有限差分法对方程进行数值求解，结果表明，如上述论文所述，粘性力和惯性力在最终平衡中并不重要。
An extension is made of the α-effect model of the earth's dynamo into the nonlinear regime following the prescription of Malkus & Proctor (1975). In this model, the effects of small-scale dynamics on the α-effect are suppressed, and the global effects of induced velocity fields examined in isolation. The equations are solved numerically using finite-difference methods, and it is shown that viscous and inertial forces are unimportant in the final equilibration, as suggested in the above paper.
