In this paper, the blow-up solutions of the following reaction-diffusion systems are studied: where is a bounded region and the boundary ∂D of D is smooth. Sufficient conditions to ensure the existence of the blow-up solution of this problem are obtained. For the blow-up solution, we also get an upper bound on the blow-up time and an upper estimate of the blow-up rate. Our research mainly relies on the use of the maximum principles of weakly coupled parabolic systems and the first-order differential inequality technique.
