The solution to a class of nonlinear disturbed transfers system for the femtosecond pulse laser to Nano metal film is obtained by using the asymptotic method. The asymptotic behaviors of corresponding solution to this nonlinear system are discussed. Firstly, the outer solution to the reduced problem is solved. Next, a functional is constructed and its generalized variational is calculated, with its variational equivalent to zero. Thus the Lagrange multiplicator is found. Then, a generalized varitational iteration expansion is constructed by using the varitational principle. Therefore, arbitrary times of iteration expansions for the corresponding system can be solved successively. At the same time, the uniform convergence to the related expansion is accounted by using the variational theory of functional analytic. An example is enumerated, and by using the simulation method, the graphs of surface for its solution are given. From the results obtained in this study, it is validated that the solving method for nonlinear disturbed transfers system to Nano metal film can be provided in a simple and valid manner by using the generalized variational iteration. And it also has a general theoretical value and a wide application potential.
