本文提出的渐近法有效地解决了有限大阻尼二自由度非自治系统(?)+2ni(?)i+ωi~2 xi=gi(t)+εfi(x_1,(?),x_2,(?)_2,t)(i=1,2) 问题.
The asymptotic method proposed in this paper effectively solves the problem of finitely damped two-degree-of-freedom nonautonomous system (?) + 2ni (?) I + ωi ~ 2 xi = gi (t) + εfi (x_1, ?) _ 2, t) (i = 1,2) problem.
