论文摘要
在本文中，我们关注通过分层介质传播声波。在空间变化的密度和熵场的情况下，具有混合非线性的培养基中非线性几何光学的传输方程。除二次非线性外，该方程还包含一个立方非线性项。我们认为热力学数量仅取决于高度的气氛。实际研究了实际气体参数，密度和熵衰减参数对溶液分解的影响。
In this paper, we concerned with the propagation of sound waves through stratified media. Transport equation of nonlinear geometric optics in media with mixed nonlinearity, in the case of spatially varying density and entropy fields, is derived; this equation contains a cubic nonlinear term in addition to the quadratic nonlinearity. We consider an atmosphere where thermodynamic quantities depend on the height only. Effects of real gas parameters, density, and entropy attenuation parameters on the breakdown of the solution are investigated numerically.
