This paper is an attempt to give inferential reasoning and solution to thin film vibration equation. 试图对薄膜振动方程加以推导和求解。
The most interesting features of these new methods are their simplicities and their excellent accuracies in a wide range of values of oscillation amplitudes. 提出的新方法都不要求非线性振动方程中含有小参数及位移的线性项。
