摘要
应用扰动广义Hamilton系统理论研究Rayleigh_Benard对流三维方形单元Pattern周期流线的存在性· 所得结果说明本文的方法给出了三维对流模型的流线周期行为的清晰描述 。
By using the theory of the generalized perturbed Hamiltonian systems, it is shown that there exist periodic stream lines in the three_dimensional square cell pattern of Rayleigh_Benard convection. The result means that our method enables this three_dimensional flow pattern to be described in an unambiguous manner, and some experimental results of other authors can be explained.
