摘要: Abstract : This book is devoted to the approximate asymptotic methods of solving problems in theory nonlinear oscillations met many fields physics and engineering. It intended for wide circle engineering-technical scientific workers who are concerned with oscillatory processes. Contents include following: Natural quasi-linear systems; The method phase plane; influence external periodic forces; mean; Justification methods.
