摘要
一般情况下,非定域势中的量子通量并不守恒,作者证明了在半经典极限情况下可守恒。
Conservation of a quantum mechanical flux defined by the Heisenberg equation is studied in the presence of non-local potentials. This quantum mechanical flux, in general, does not conserve. It is found that the flux comes to be conserved in the semi-classical limit.
