在大长高比Γ=30,弱分离比ψ=-0.20参数下,通过二维流体力学基本方程组模拟了混合流体Rayleigh-Benard对流运动.通过变化相对瑞利数r,在对流分叉曲线鞍结点处得到了双局部行波,分析了双局部行波斑图的形成过程及时空结构,讨论了其动力学特性.%Under the parameters of a large aspect ratio(Γ=30),and a weak separation ratioψ=-0.20,the hybrid fluid Rayleigh-Benard convection motion is simulated through the two-dimen-sional fluid mechanics basic equation system or group.The doubly localized traveling wave in the convection bifurcation saddle node is obtained through the variation in relative Rayleigh number r.The formation process of doubly localized traveling wave spot diagram and spatio-temporal structure are analyzed,whose dynamic behaviors are discussed in this paper.
