摘要
In the study of the regularity criterion of Leray-Hopf weak solutions to the 3D Navier-Stokes equations, the Beale-Kato-Majda type criterion is obtained in terms of the horizontal derivatives of the two velocity components integral(T)(0) parallel to del(h (u) over tilde (S))parallel to(B over dot infinity,infinity 0) ds < infinity, <(u)over tilde> = (u(1), u(2), 0), del(h)(u) over tilde = (partial derivative(1)(u) over tilde, partial derivative(2)(u) over tilde, 0).
