【Abstract】 The propagation of the spatial dark soliton has been studied using the so called adiabatic approximation of the perturbation theory in the presence of the linear gain and the two photo absorption .It can be found that initial phase has the important influence on the propagation of spatial dark soliton,such as stability,distance etc.更多还原
