And beginning with a perturbed nls equation , using a multi - scales perturbation expansion , we get the zero order and the first order equations , discuss the eigenstates of the operator in the equations , induct relevant " derivative states " , form the completeness of the bounded eigenstates of the associated operator in li space , and expand the corresponding parameters in the closure , get a series evolution equations of the coefficients in the expanded formulas , find the first order approximate solution by researching the evolution equations . this paper also gives the basis of this method - the completeness we have formed and the singular perturbation technique
