The oscillation of solutions for the systems of a class of impulsive neutral parabolic partial differential equations was studied.By employing the method of integral average and Green's theorem
necessary and sufficient conditions for oscillation of all solutions of the systems were obtained under Newmann's boundary condition.By using first order impulsive neutral type differential equations
a sufficient condition for oscillation of all solutions of the systems was presented.The results reveal the impulsive and delay's influence on the oscillation.
