摘要：

The averaging method for time-dependent quantum systems is used to construct quantum mechanical analogues of the perturbation expansions by Poincare and by Kolmogorov for time-dependent operators. An example shows that the resulting two perturbation algorithms are much better than the usual time-dependent perturbation theory. (C) 1997 Elsevier Science B.V.
