The continuous beam can be soled by using singular functions and the method of superposition. 藉助奇異函數和疊加法，導出了帶有奇異函數的三彎矩方程。
Double-Fourier seriestype solutions are obtained by utilizing the superposition method and by taking advantage of symmetry inherent in the problem. 利用疊加法和本問題所固有的對稱性優點得到了重富立葉級數解。
The superimposition method adds a signal at its resonance frequency with a signal at the subharmonic frequency. 本研究並提出兩類波形以有效誘發穴蝕效應，分別為串接法及重疊法。
