【Abstract】 The precise time-integration method is proposed for solving delay parabolic equation with initial condition and boundary condition.The local truncation error of the method is O(Δx4).The method is unconditionally stable.Numerical example shows that the method has high accuracy.So the precise time-integration method is a practical method.更多还原
