摘要：

We consider the long time behavior of solutions to the magnetohydrodynamics- alpha model in three spatial dimensions. Time decay rate in L-2-norm of the solution is obtained. Similar results for a generalized Leray- alpha-magnetohydrodynamics model are also established. As a by-product, an optimal time decay rate for the Navier-Stokes- alpha model is achieved.
