<正>The new method proposed recently by Friedberg,Lee,and Zhao is extended to obtain an analytic expansion for the ground-state wavefunction of a time-dependent strong-coupling Schrodinger equation.Two different types of the time-dependent harmonic oscillators are considered as examples for application of the time-dependent expansion.It is shown that the time-dependent strong-coupling expansion is applicable to the time-dependent harmonic oscillators with a slowly varying time-dependent parameter.
