一类拟线性抛物系统解的整体存在性

Global Existence of the Solution for a Class of Semilinear Parabolic Systems

采用非线性分析的方法，研究一类生物种群动力学中的拟线性抛物系统。

Use the methods in nonlinear analysis, study a class of nonlinear reactiondiffusion systems with cross diffusion effects in population dynamics, and obtain the global existence of the solution.
