旋转层对流的数值模拟结果被用来计算平均场电动力学的α效应。针对不同的系统规模进行了计算。结果发现，结果与系统尺寸密切相关，只有当系统尺寸与典型涡旋尺寸相比较大时，才能得到有物理意义的结果。
The results of numerical simulations of convection in a rotating layer are used to compute the α-effect of mean-field electrodynamics. The computations are carried out for different system sizes. It is found that the outcomes can depend critically on the system size, and that physically meaningful results can only be obtained if the system size is large compared with the typical eddy size.
