摘要
从正压涡度方程出发,利用截谱方法,讨论波动与基本流之间的相互作用,得到了波流之间能量转换的条件。在引入时空缓变量后,导出Sine-Gordon方程。
Starting from the baratropic moldel and using the method of the truncate spectrum,this paper discusses interaction between wave and basic flow and identifies conditions of energy transforming between wave and flow.It gets the Sine Gordon equation and its solitary wave solution.
