论文摘要
我们通过具有非恒定比例因子的轴对称beltrami场来构建3D EULER方程的行驶波解决方案。它们形成一个涡流环，其嵌套不变托里由比例因子的水平集组成。
We construct traveling wave solutions to the 3d Euler equations by axisymmetric Beltrami fields with a non-constant proportionality factor. They form a vortex ring with nested invariant tori consisting of level sets of the proportionality factor.
