除了在环形容器中，3 He-A中的序参量在表面必须有奇点。这种奇异性的例子，并推导出曲面拓扑结构和奇异性的种类之间的关系。讨论了环流沿着表面轮廓的量子化，并给出了通过表面奇点运动的超流衰减的例子。
Except in a toroidal container, the order parameter in 3He-A must have singularities at the surface. Examples of such singularities are given, and a relation between the surface topology and the kinds of singularities is derived. Quantization of circulation along surface contours is discussed, and examples of the decay of superflow through the motion of surface singularities are given.
