Periodic Solutions of the Second Order Differential Equations with Asymmetric Nonlinearities
【摘要】 研究了一类具有非线性项二阶Duffing方程解的一些性质 ,证明了在特殊限制条件时方程有惟一的周期解并给出了共振点处周期解存在的充分条件
【Abstract】 The Duffing equation was studied to understand its solution characteristics. It is found the equation possesses a unique periodic solution with certain restrictions. The sufficient conditions for existence of the periodic solution at resonance were also established.
