在本章中,我们将再次考虑含有小参数e的方程。近似方法一般导致渐近级数,而不是在前一章研究的收敛级数;见9.2节的基本概念和更多的讨论在桑德斯和Verhulst(1985),第2章。这种近似的渐近性质在许多问题中更自然;该方法也证明是非常强大的,它不限于周期解。
In this chapter we shall consider again equations containing a small parameter e. The approximation method leads generally to asymptotic series as opposed to the convergent series studied in the preceding chapter; see section 9.2 for the basic concepts and more discussion in Sanders and Verhulst (1985), chapter 2. This asymptotic character of the approximations is more natural in many problems; also the method turns out to be very powerful, it is not restricted to periodic solutions.
