英文摘要：

In order to get the numerical solution of a class of two-dimensional nonlinear Fredholm integral equations,Adomian decomposition method（ADM）is presented in this paper.The nonlinear term of twodimensional nonlinear Fredholm integral equations is replaced by Adomian polynomial,so that the Adomian series solutions are obtained.It is proved that the obtained Adomian series solutions will converge to the exact solution of original equation on certain conditions.Meantime,the maximum absolute truncated errors between the Adomian series solution and exact solution is given out.Finally,it is verified by a numerical example that the method is effective and the theory is valid.
