摘　　要：研究一类带有非局部边界条件的抛物型方程组解的整体存在与有限刻爆破.主要通过构造上、下解,利用比较原理得到定理的证明.We have studied global existence and blow-up in finite time for the solutions to certain parabolic systems with non-local boundary conditions. Constructing the supper and subsolutions and using the comparision principle, we have acquired the proof of the theorem.
