摘要	The transient process through a quantum dot is studied via the impurity Anderson model. The nonequilibrium Green's function technique and the Feynman path-integral method are used. The dependence of the renormalized transition time tau/tau(0) for electrons tunneling through the dot with spin sigma is found depending on the occupation probability [n(delta)] of electrons with the opposite spin <(sigma)over bar> in the dot. We conclude that the electronic correlation effect will shorten the time required for a system to arrive at a steady-state.
