中文摘要 | 本文利用廣義函數的拉普拉斯轉換解出瞬變聲波的質源、偶源,雙偶源三種基本 解。此三種基本解的物理意義分別是瞬變點質率,點力,及點應力。此三者即代表流體動力 聲波之最基本肇因。利用這些基本解的不同分佈,本文的解答將可能應用到更複雜的瞬變聲 學問題。 |
英文摘要 | Three fundamental solutions of transient acoustic waves, source, dipole, and quadrupole, are solved by the Laplace transforms of the generalized functions. The physical meaning of these three fundamental solutions are transient point mass rate, point force, and point stress, respectively. And they are three most fundamental causes of hydrodynamic sound. The solutions of this study hopefully may be applied to more complicated transient acoustic problems by distributions of these three fundamental solutions. |
