英文摘要：

The rationalized Haar functions are used to solve the solution of fractional order Fredholm integrat equa- tion of the second kind. The integral equation can be reduced to a system of algebraic equations by using ration- ahzed Haar wavelet and collection method. Finally,the numerical solution of fractional integral equation with exact solution and the numerical solutions using Haar wavelet are compared by error analysis and numerial examples. The result shows that the algorithm has high accuracy.
