摘要
本文借助Volterra级数理论,多维拉氏变换和多维Z变换,用解析方法计算了非线性分析中著名的Duffing方程的Volterra核。
In this paper, Volterra kernels of Duffing equations which are well-known in nonlinear analyses, are calculated analytically by means of volterra series theory, multidimen- sional Laplace transform and multidimensional Z transform.
