摘要: 大气中许多模式可化为F″=AF/(F+B≠0)一类非线性常微分方程,利用常微分方程定性理论说明了该方程存在非线性波解,讨论了其周期的计算问题,并求得了波解及其周期的近似表达式。Abstract: A number of atmospheric models can be transformed into a nonlinear ordinary differential equation as expressed in F″=AF/(F+B≠0).Its nonlinear wave solution and calculation of the period are theoretically approached with the qualitative method of the equation. An approximated expression of the wave solution and its period are obtained.
