摘要

摘要提出了一种生成布尔格斯方程解的方法，该方程描述了非线性耗散介质中波与线性增长波面的相互作用。使用了描述这些相互作用的精确解以及方程的对称特性。结果表明，上升的波前能够与耗散竞争，并在时间上压缩信号。相反，陡度下降的波面会 "拉伸 "信号。

Impact of the Wavefront on a Nonlinear Wave in a Dissipative Medium

A method for generating solutions of the Burgers equation, which describe the interaction of waves in a nonlinear dissipative medium with a linearly growing wavefront, is proposed. The exact solutions describing these interactions and symmetry properties of the equation are used. It is shown that the rising wavefront is able to compete with the dissipation and compress the signal in time. On the contrary, the wavefront with the decreasing steepness “stretches” the signal.
