In this paper the method of first integral for further reduction of normal forms is introduced.So far, Scientists have proposed a variety of different ways to calculate normal form.The common methods include Matrix representation method, Conjugate operator method, method of Lie algebra and KOW method.KOW method [1,2] is a way to compute normal form based on a new calculation to definite the order of polynomial and the definition of n-th order normal form, which is proposed by Kokubu, Oka and Wang based on linear grading theory of Baider and Sanders.
