摘　　要：研究了一类具有非局部源的退化抛物型方程组解的性质,运用上下解方法以及正则化技巧证明了局部解的存在惟一性,并且得出了该方程组解的整体存在的充分条件.The properties of solutions for a degenerate parabolic system with nonlocal sources are investigated in this paper. The existence and uniqueness of local solution are proved by the upper and lower solutions method and the regularization skill, and the sufficient conditions for the existence of global solution are obtained.
