摘要: The aim of this paper is to describe the general averaging principle and discuss particular case single-frequency systems, systems with constant frequencies Hamiltonian systems. We show how stroboscopic method, which a method nonstandard perturbation theory differential equations, can be used in kind problems. give various examples illustrate simplicity effectiveness method.
