Then we give some concrete examples about the Adomian polynomials and use MATLAB to obtain the results of Adomian polynomials decomposition. This paper is pided into four chapters. The first chapter is the introduction, we make a brief description about the historical background and development process of the Adomian decomposition method, and summarize some foreign scholars’ research results and application of this method. Then, the power series method of differential equation is introduced. After that, we make a detailed introduction about the Adomian decomposition method and the application of it. And as for this method, we give a few examples. In the fourth chapter, the application of Adomian polynomials is realized by MATLAB programming. Finally, the summary of this paper is made.
