一个非线性偏微分方程的求解

A Solution to the Non-Linear Partial Differential Equation

讨论非线性偏微分方程uxt=e-u+e-2u的求解,方法是通过变换把该方程变为Riccati方程,进而得到该方程的一个行波解.

The way to get the solution to non-linear partial differential equation is to change the equation uxt=e-u+e-2u into riccati equation to get a traveling-wave solution.
