  • 在這篇論文中,我們探討無黏滯性的Burgers equation,以及Burgers equation with source term。首先,為了尋找自我相似解,我們將這些偏微分方程式轉換成常微分方程式。經由觀察到這些常微分方程式是同質的,因此我們利用分離變數法對這些常微分方程式求解,並討論解的行為。

    This thesis studies the Burgers equation without viscosity, and the Burgers equation with source term. First, to obtain the solution in self-similar form, the PDEs are transformed into ODE. Then, from the observation that the ODEs are homogenous, the method of separation is used to solve these equations.
