英文摘要：

By introduction and use of the method of Hirota′s bilinear derivative transform , the derivative nonlinear Schr?dinger equation with vanishing boundary condition has been solved .The one and two soliton solutions are derived as two typical examples in the illustration of the general procedures .Their equivalence to the existing soliton solutions found with other approaches has also been discussed in detail .The elastic collision among the slitons has been manifested through an example of two soliton case .The evolution of one and two soliton solution with respect to time and space has been clearly demonstrated in figures .
