In this paper,we investigate several regularity criteria to the 3D incompressible magnetohydrodynamic equations.These criteria are based on certain assumptions made in partial elements of the velocity gradient tensor and pressure,respectively.By making use of the Littlewood-Paley decomposition,we show that the solution(u,b)can be smoothly extended after time T if any two groups of functions(∂1u1,∂1b1),(∂2u2,∂2b2)and(∂3u3,∂3b3belong to the space L1(0,T;B∞,∞). 展开更多
