摘要
讨论带有非线性边界条件的快扩散与慢扩散耦合的方程组，给出了解整体存在的充分必要条件.
In this paper the global solutions and blow-up problems are studied for the fast-slow diffusion systems with nonlinear boundary conditions. The necessary conditions and sufficient conditions for the global existence of all positive solutions are obtained.
