【Abstract】 This paper deals with the initial-boundary value problem under the third nonlinear boundary condition for a kind of nonlinear parabolic equations. By applying the maximum value theory of parabolic equation and convex method,it is proved that the blow up of solution in a definite time under some assumed conditions. The conclusion popularizes the results of refernces [7-9].更多还原
