摘要：

Viewing electron transmission as a probability flow problem, we study the stream lines of the flow. Velocity nodes are found at the points of wavefunction stationary phase, while vortices occur at wavefunction nodes. Analytical results are given for stream lines around such points. The sum of the action along a closed path and the charge times the enclosed magnetic flux is quantized in terms of the number of ''quantum vortices''.
