Abstract
In this paper, the defect of the Two-Time Expansion method is indicated and an improvement of this method is suggested. Certain examples in which the present method is used, are given. Moreover, the paper shows the equivalence of the improved Two-Time Expansion Method and the method of KBM (Krylov-Bogoliubov-Mitropolski).
