利用修正的Clarkson-Kruskal(CK)直接方法得到了含色散项的Zabolotskaya-Khokhlov(简写为DZK)方程的对称、约化和一些精确解,包括双曲函数解,有理函数解,三角函数解等,同时得到了该方程的守恒律。
Using the modified Clarkson-Kruskal direct method, the symmetries reductions of the Zabolotskaya-Khokhlov equation with a dissipative term were obtained. By solving the reduction equa- tions, a great many of solutions were derived, including the rational function solutions, the trigonometric function solutions, hyperbolic function solutions and so on. The conservation laws were given at last.
