【Abstract】 The spatial variable of the time-dependent Schrdinger equation was discretized,and the time-dependent part was treated by using the time average technique,then the time evolution of the system was simulated by the precise intergration method.The numerical results showed that this method was effective,and the second-order method was accurate up to fourth-order.Furthermore,it was unconditionally stable.更多还原
