中文摘要：

在长高比Γ=40、分离比ψ=-0.6情况下,通过流体力学基本方程组的数值模拟,得到了一种新的有趣斑图,即单侧缺陷摆动对传行波。通过分析单侧缺陷摆动对传行波各物理场随时间变化的等值线图、波形图,讨论了其形成过程及时空动力学特性。进一步对比不同相对瑞利数下的单侧缺陷摆动对传行波,探讨了缺陷数、缺陷周期以及缺陷方向等缺陷特征对相对瑞利数的依赖性。

英文摘要：

Based on numerical simulations of fully hydrodynamic equations, a new interesting pattern was founded in the condition of aspect ratio = 40 and separation ratio b = - 0.6. The new pattern was named as counter propagating wave with unilateral defect and oscilation. By analysising isopleth patterns and wave patterns of each field as a function of time, the formation process and spatio-temporal dynamics of counter propagating wave with unilateral defect and oscilation were studied. Further more, comparing counter propagating wave with unilateral defect and oscilation under different reduced Rayleigh numbers, the dependence of defect characterics, such as defect amount, defect period and defect direction, on re- duced Rayleigh numbers, was discussed.
