In the present paper, the blow up of smooth local solutions for a class of nonlinear parabolic equations u;t =โ(a(u)โu) + f(x; u; q; t) (q = |โu| 2 ) with Dirichlet boundary conditions are studied. By constructing an auxiliary function and using Hopf's maximum principles on it, the su cient conditio
