摘要：
In this paper we consider the regularity criteria for weak solutions to the 3D MHD equations. It is proved that under the condition b being in the Serrin's regularity class, if the pressure p belongs to L-alpha,L-gamma with + 2/alpha + 3/gamma <= 2 or the gradient field of pressure del p belongs to L-alpha,L-gamma with 2/alpha + 3/gamma <= on [0, T], then the solution remains smooth on [0, T].
