摘　　要：Fredholm积分方程广泛出现于应用数学、物理、工程等领域。使用sinc配置方法得到具有退化核的第二类Fredholm积分方程的数值解,该方法把Fredholm积分方程的计算变换为线性方程组,分析该方法的收敛性,数值试验结果表明该方法非常有效。Fredholm integral equations extensively appeare in applied mathematics, physics and engineering. Numerical solution of Fredholm integral Equations with degenerate kernel based on Sinc-collocation Method is considered here. The method is used to reduce the computation of Fredholm integral Equations to the systems of algebraic equations. Also, convergence of the method is given. Some numerical results show that the method is very effective.
