中文摘要：

讨论了一类具有积分边界条件的二阶常微分方程非局部边值问题的数值解．对非局部积分边界条件采用了离散的多点边值问题进行逼近，通过常系数情况下解的局部性质，建立了这类边值问题的指数型差分格式，并且给出了格式的误差分析，证明了格式是一致收敛的．

英文摘要：

This paper discusses the numerical solution of second order differential equation with integral boundary conditions. The integral boundary conditions are proved by multipoint boundary value problem. By discussing the local properties of the solution to the corresponding problem with constant coefficient, ference scheme. The error estimate is calculated, convergent. we present a exponential fitted finite difwhich shows that this method is uniformly
