摘要：
In light of the phi-mapping topological current theory, two important vortex structures in two-component spinor BEC-the velocity field vortices and the Mermin-Ho vortices are discussed. It is revealed that these two different kinds of vortices are created respectively from the zero points of two different order parameter configurations in the condensates, and both their topological charges, locations and motions can be determined by the phi-mapping theory.
