  "abstract": "We show that any smooth stationary solution of the 3D incompressible Navier-Stokes equations in the whole space, the half space, or a periodic slab must vanish under the condition that for some $0 \\le \\delta \\le 1<L$ and $q=6(3-\\delta)/(6-\\delta)$, $$\\liminf_{R \\to \\infty} \\frac 1R \\|u\\|^{3-\\delta}_{L^{q}(R<|x|<LR)}=0.$$ We also prove sufficient conditions allowing shrinking radii ratio $L= 1+R^{-\\alpha}$. Similar results hold on a slab with zero boundary condition by assuming stronger decay rates. We do not assume global bound of the velocity. The key is to estimate the pressure locally in the annuli with radii ratio $L$ arbitrarily close to 1.",
