摘　　要：给出受外激励二阶参变系统周期解的新的计算方法，它对于相当广泛一类方程均可适用，并可对解的稳定性作出判断。In this paper a new method is suggested. By using this method not only the periodic solutions of the 2nd order parametric systems under external excitation can be solved, but the stability of these periodic solutions can also be decided.

关 键 词：二阶参变系统 周期解 稳定性
