讨论了旋转超流体中周期涡旋排列的一般性质。根据对称空间群和循环数对不同可能的结构进行分类。对超流体3He-A中几种涡结构进行了数值计算。计算是在金兹堡-朗道地区完成的，但该方法适用于所有温度。在磁场与旋转速度形成的平面上，构造了涡旋的相图。讨论了六种平衡涡解的特性。其中之一，锁定涡，在以前的文献中没有被考虑过。当旋转速度超过2.6 rad/s时，涡片形成旋转3He-A的平衡状态。定性分析结果与实验结果基本一致。
We discuss the general properties of periodic vortex arrangements in rotating superfluids. The different possible structures are classified according to the symmetry space-groups and the circulation number. We calculate numerically several types of vortex structures in superfluid 3He-A. The calculations are done in the Ginzburg-Landau region, but the method is applicable at all temperatures. A phase diagram of vortices is constructed in the plane formed by the magnetic field and the rotation velocity. The characteristics of the six equilibrium vortex solutions are discussed. One of these, the locked vortex 3, has not been considered in the literature before. The vortex sheet forms the equilibrium state of rotating 3He-A at rotation velocities exceeding 2.6 rad/s. The results are in qualitative agreement with experiments.
