| 摘 要： | 通过构造四族Lax型熵-熵流得到了一个二次流系统整体熵解的存在性,并应用动力学公式与补偿列紧方法相结合的思想极大地简化了Young归约这一极其关键、困难的步骤,对此提供了另外一个非常简洁的证明.

| Abstract: | In this paper,the existence of global entropy solution for a system of quadratic flux is obtained by constructing four families of entropy-entropy flux of Lax type.Besides,by applying the compensated compactness method coupled with some basic ideas of the kinetic formulation,the crucial and difficult step is considerably simplified,and a much concise proof for it is also given. |
