摘　　要：文章研究一类耦合抛物型方程组的初边值问题,给出了当初值和增长阶数满足一定条件时,解在有限时刻爆破的充分条件.研究结果是部分文献结果的推广.To studies the initial boundary value problem of a coupled parabolic equation system with nonlinear source. Since the explicit solution can not be solved,the discussion to the property of the solution is important. It is showed that under some conditions the solutions blow up in finite time by energy method.

关 键 词：耦合抛物型方程组 能量法 解的爆破 爆破的条件
