摘　　要：考虑有重力影响的一维两相多组分聚合物驱模型的黎曼问题。借助“间断流通量思想”将方程组解耦,在相平面上分析方程组的基本波,给出黎曼问题的完整分类并构造出黎曼解,观察到由几个复合波组成的新颖的黎曼解结构。The Riemann problem for the one-dimensional two-phase multicomponent polymer flooding with the presence of gravity is considered.We use the idea of discontinuous flux to decouple this system,analyse the elementary waves of this system in the phase plane,give the complete classification of the corresponding Riemann problem,construct the exact Riemann solutions and then discover the novel Riemann solution construction,which consists of several compositive waves.
