摘要
考虑一类带有齐次Dirichlet边界条件且反应项分别为指数形式和幂函数形式的半线性抛物型方程组,利用比较原理得到了方程解爆破的充分条件,由数学分析原理和最大值原理得到了爆破解的爆破速率估计.
A semi-linear parabolic equation with null Dirichlet boundary condition is studied.The response items of system are exponential and power functions. By using comparison principle, the sufficient condition for blow-up of solution is established. The blow-up rates of the solution to parabolic systems have been discussed by using the mathematical analysis principle and maximum principle.
