摘要 讨论了带有热源项的非线性扩散方程.通过一种直接简洁的方法得到了几种精确解.该方法可用于更高阶演化方程的求解问题。 A straightforward and concise method is used to construct exact solutions of the nonlinear diffusion equations with source. Some exact solutions are obtained due to this direct method. This method can be used to seek for exact solutions of higher-order evolution equations.
