摘要：

The decomposition theory of the U(1) gauge potential has been studied. A rigorous proof of the London assumption is given. By making use of this gauge potential decomposition and the phi-mapping topological current theory, the precise expression for (Δ) over right arrow x (V) over right arrow is obtained, and the topology in quantum mechanics is discussed.
